Magnetic Field Shielding: A Practical Guide

Posted by Security Team on

Your starter guide to understanding and protecting against low-frequency magnetic fields

When most people think about EMF protection, they immediately think of Faraday cages, RF-blocking fabrics, and shielding paint. And while those solutions are excellent for blocking high-frequency radiation but they do little for low-frequency magnetic fields.

This is one of the most common misconceptions in EMF protection—and it's time to clear it up.

If you live near a transformer, have a smart meter on your bedroom wall, use large inverters in your van conversion, or simply want to reduce magnetic field exposure from household appliances, this guide will help you understand what magnetic fields are, where they come from, and most importantly, how to shield against them effectively using proven solutions.

In This Guide

Quick Start: What You Need to Know in 60 Seconds

The Problem: Magnetic fields from power sources (smart meters, inverters, transformers) can't be blocked by regular EMF fabrics—they need special materials.

The Solution: Y-Shield magnetic shielding plates redirect magnetic fields using specialized metal (like redirecting water flow with a channel).

For Most People:

  • One M6L-64 plate behind your bed
  • Plus grounding kit
  • Equals a significant reduction in magnetic field exposure

Installation Time:

  • DIY mounting: 30 minutes (like hanging a picture)
  • Electrician for grounding: 30 minutes
  • Total time: About 1 hour

First Step: Either measure your exposure with a magnetic field meter, or simply install the shielding behind any wall with a smart meter or electrical panel.

Can't Do It Yourself? The mounting is DIY-friendly, but you'll need a licensed electrician for the final grounding connection (it's a safety requirement).

Results vary depending on installation conditions, materials used, substrate type, single-phase vs. three-phase power, source strength, and distance from the source.

Understanding the Difference: RF vs. Magnetic Fields

Let's start with the fundamentals. Understanding the difference between radiofrequency (RF) radiation and magnetic fields is crucial to choosing the right protection.

Radiofrequency (RF) Radiation (think: Wi-Fi, cell phones)

  • High-frequency electromagnetic fields
  • Sources: Wi-Fi routers, cell towers, mobile phones, Bluetooth devices, smart meters (the wireless communication part)
  • How to block it: Faraday fabric, RF shielding paint, metal mesh - these all work great for RF
  • How it behaves: Travels through air but bounces off or gets absorbed by metal/conductive materials

Low-Frequency Magnetic Fields (ELF) (think: power lines, appliances)

  • Extremely low frequency fields (the 50-60 Hz from your power grid)
  • Sources: Power lines, transformers, electrical appliances, inverters, building wiring, smart meters (the power supply part)
  • Important: Standard Faraday fabrics and RF shielding materials DO NOT work for magnetic fields
  • What you need instead: Special high-permeability metal (think of it as "metal that magnetic fields prefer to travel through")
  • How it behaves: Passes right through walls, wood, regular metal, and most building materials

The key takeaway: That expensive Faraday fabric lining your walls is doing absolutely nothing for the magnetic field coming from the transformer down the street or the inverter in your van. Magnetic fields need a completely different approach—that's what this guide is about.

Common Sources of Magnetic Fields in Your Environment

Understanding where magnetic fields come from helps you make informed decisions about where to focus your shielding efforts:

In Homes:

  • Smart meters (particularly the power supply component)
  • Building transformers and electrical panels
  • High-current appliances (electric cookers, hair dryers, microwave ovens)
  • Electrical wiring in walls (especially aluminum wiring or poorly balanced circuits)
  • Nearby power lines and substations
  • Voltage stabilizers and distribution equipment

In Van Conversions and Mobile Living:

  • Power inverters (these are often the biggest culprits)
  • Battery management systems
  • Solar charge controllers
  • Shore power connections
  • Alternators and electrical systems
  • Induction cooktops

In Bedrooms (High Priority Areas):

  • Electric blankets and heated mattress pads
  • Clock radios and bedside electronics
  • Wall-mounted smart meters on the opposite side of the wall
  • Electrical outlets and wall wiring
  • Fans and air conditioning units

The good news? You don't need to eliminate all these sources. Distance is your friend, and we'll talk about that next.

Distance is Your Best (and Free) Protection

Before you spend a dollar on shielding materials, understand this: magnetic fields get dramatically weaker as you move away from the source.

This is called the "inverse square law" but forget the technical name. Here's what it means in plain English:

Simple Examples:

  • Double your distance = 75% less exposure
    Move from 10cm to 20cm away = exposure drops to 25% of what it was
  • Triple your distance = 89% less exposure
    Move from 10cm to 30cm away = exposure drops to just 11% of what it was
  • Move 5x farther away = 96% less exposure
    Move from 10cm to 50cm away = exposure drops to just 4% of what it was

Real-World Applications:

  • Bedroom: Moving your bed just 30-50 cm (1-2 feet) away from a wall with a smart meter can reduce exposure by 75-90%
  • Van/RV: Positioning your inverter 50 cm from your sleeping area instead of 20 cm = massive difference
  • Appliances: Keeping hair dryers and electric tools at arm's length during use = significantly less peak exposure
  • Workspace: Arranging your desk away from electrical panels = simple but effective protection

The Bottom Line: Sometimes the best "shielding" is just rearranging your furniture. It's free, takes 10 minutes, and can reduce exposure by 75-90% in many cases.

When distance isn't enough: If you're in a situation where you can't move farther away (smart meter on bedroom wall, inverter location fixed in van, transformer right outside your window), that's when magnetic field shielding products make sense.

How Magnetic Field Shielding Actually Works

Here's the key difference: RF shielding blocks the signal. Magnetic field shielding redirects it.

The Water Channel Analogy:
Think of magnetic fields like water flowing downhill. You can't stop water from flowing, but you can redirect it with a well-placed channel. Special high-permeability metal acts like that channel—it gives the magnetic field an "easier path" to travel through, routing it around the area you want to protect instead of letting it pass through.

In Plain English:

  • Regular RF shielding fabric = bounces signals away (like a mirror reflects light)
  • Magnetic field shielding = creates a path for the field to flow around you (like water flowing around a rock in a stream)

What Makes It Work (The Four Key Factors):

1. The Right Material Matters

  • You need special high-permeability metal (metal that magnetic fields "prefer")
  • Standard steel from the hardware store provides minimal protection
  • Y-Shield products use purpose-engineered alloys that are 10-50x more effective

2. Thickness and Layers Matter

  • Thicker shielding = more magnetic field gets redirected
  • Multiple thin layers often work better than one thick layer
  • That's why Y-Shield M6L products use 6 thin layers instead of one thick one

3. Complete Coverage Matters

  • Gaps and holes reduce effectiveness
  • The shield needs continuous coverage over the protected area
  • Think of it like waterproofing—a gap defeats the purpose

4. Grounding is Essential

  • Proper grounding makes the shielding work better AND keeps it safe
  • It's like giving the magnetic field a "final exit path"
  • This is why you need an electrician (it's an electrical safety requirement)

Bottom Line: You can't block magnetic fields, but you can redirect them. The right materials in the right configuration create a "path of least resistance" that routes the field around your living space.

Installation Overview (The Simple Version)

Nervous about installation? Don't be. Here's what you'll actually do:

What You'll Do Yourself (30-45 minutes):

  1. Clean the wall where you'll mount the shielding (just like prepping to hang a picture)
  2. Stick the shielding plate to the wall using heavy-duty adhesive strips or screws
  3. Attach a grounding strap (it's like conductive tape—peel and stick)
  4. Mount a small grounding box near the floor (4 screws, takes 5 minutes)

What the Electrician Does (30 minutes):

  1. Connects the grounding system to your home's electrical ground (safety requirement)
  2. Tests everything to make sure it's working properly

What You WON'T Have to Do:

  • Any electrical work beyond basic mounting
  • Anything dangerous or code-violating
  • Anything that can't be reversed if you're renting (adhesive strips work great)
  • Cut into walls or run wiring through your home

Skill Level: If you can hang a picture and follow instructions, you can do the DIY part. The electrical connection is required by law to be done by a professional, but that's typically a quick 30-minute job.

Can I Really Do This Myself? Yes, for the mounting. But hiring an electrician for the final grounding connection is:

  • Required by law (Australian electrical standards)
  • Required by Y-Shield (manufacturer safety specifications)
  • Smart for your safety (proper grounding prevents electrical hazards)

Think of it like installing a ceiling fan: you can mount it, but an electrician should wire it.

Detailed Installation Guide

Based on official Y-Shield manufacturer specifications and technical datasheets, here's how to properly install magnetic field shielding in your space.

Important Safety Requirements (Manufacturer Specifications)

CRITICAL SAFETY INFORMATION - Please Read

Before you start, understand these safety requirements from Y-Shield. They're not just "suggestions"—they're legal requirements and safety essentials.

Who Can Do the Electrical Work:

  • You can: Mount the shielding plates, apply grounding straps, install grounding boxes
  • You cannot: Make any electrical connections to your home's electrical system
  • Licensed electrician must: Connect grounding to earth ground, verify system compatibility, test for safety

Why This Matters:

  • Improper grounding can cause electric shock, fire, or death
  • It's required by Australian law (AS/NZS 3000)
  • It's required by Y-Shield manufacturer specifications
  • Your home insurance may not cover DIY electrical work

Electrical System Requirements:

  • Your electrician will verify you have the right type of electrical system (they'll know what to check)
  • Technical details for your electrician: Must be TN-S, TT, or IT system (never PEN-conductor systems)
  • Technical details for your electrician: Requires RCD (safety switch) ≤ 30 mA
  • If you're not sure: Just tell your electrician you're installing EMF shielding that needs grounding—they'll know what to check

What This Requires:

  • Licensed electrician visit for 30-60 minutes of work
  • This is NOT optional—it's a safety and legal requirement
  • Think of it like: you can mount a ceiling fan, but an electrician should wire it

Tools and Materials You'll Need

For M6L Plate Installation:

  • High-quality scissors or utility knife (for cutting plates if needed)
  • Cut-resistant gloves (cutting edges are very sharp)
  • Heavy-duty adhesive strips (3M Command strips) OR
  • Drill, wall anchors, and screws for permanent mounting
  • Measuring tape and pencil
  • Clean cloth and surface cleaner
  • Magnetic field meter (for before/after verification)

For Grounding System:

  • GSX10 or GSX50 grounding strap with conductive adhesive
  • GS3 grounding plate or EMF Grounding Plate Kit
  • GL-series grounding cable (appropriate length for your installation)
  • Torx® screwdriver (included with GS3/GF3 kits)
  • Licensed electrician for final earth ground connection

Step-by-Step: Home Wall Installation (Smart Meters, Transformers)

STEP 1: Measure and Identify the Source

Before purchasing materials:

  • Use a magnetic field meter to measure exposure levels at head height (sleeping areas) or seated height (living areas)
  • Identify the exact location of the highest magnetic field readings
  • Mark the wall area that requires shielding (typically 1-2 square meters for bedroom applications)
  • Take photos and note measurements for comparison after installation

STEP 2: Calculate Material Requirements

Based on your measurements:

  • M6L-64 plates (59x40 cm): Ideal for single smart meter or small area (one plate = 0.24 m²)
  • M6L-85 plates (80x55 cm): Better for larger coverage (one plate = 0.44 m²)
  • M6L-9x roll material: For areas larger than 2-3 square meters
  • Plan for 2-5 cm overlap if using multiple plates side-by-side

STEP 3: Prepare the Wall Surface

  • Clean the wall area thoroughly with a damp cloth
  • Allow wall to dry completely (critical for adhesive mounting)
  • Room temperature should be 18-24°C for optimal adhesive performance
  • If painting over the installation later, this should be done AFTER shielding is installed
  • For installations behind furniture, mark reference points before mounting

STEP 4: Cut Shielding Material (If Required)

Most people use full-size plates and don't need to cut. But if you do need custom sizes:

What You Need:

  • High-quality scissors (standard scissors dull quickly on this material)
  • Cut-resistant gloves (MANDATORY) - these edges are razor-sharp

How to Cut:

  1. Place material on flat, stable surface
  2. Use a straight edge as a guide
  3. Cut slowly and carefully
  4. Wear those gloves—seriously, the edges are extremely sharp

Important Cutting Rules:

  • M6L plates: Don't bend sharper than 20 cm radius (don't fold or crease)
  • M2L/M2A foil: Can bend to 10 mm radius (very flexible for curves)
  • Cutting weakens the laminated edges slightly—use full plates when possible

Pro Tip: Order the right size from the start to avoid cutting. The pre-sized plates are optimized for common applications.

STEP 5: Apply Grounding Strap to Shielding Material

This is done BEFORE mounting the plate to the wall:

For Plate Installations:

  • Take your GSX10 grounding strap (conductive adhesive on both sides)
  • Apply one 10-15 cm length of strap to the back edge of the shielding plate
  • The strap should extend beyond the plate edge by 30-50 cm to reach your grounding plate location
  • Press firmly for good adhesive contact with the shielding material
  • Position the extended strap so it will run vertically down to floor level when mounted

For Roll Material:

  • Apply GSX grounding strap along one edge before cutting from roll
  • For large installations (multiple square meters), use multiple grounding connection points
  • Space grounding straps every 1-2 meters for optimal performance
  • The GSX strap is double-sided conductive, so orientation doesn't matter

STEP 6: Mount the Shielding Plate

Choose your mounting method based on whether you rent or own:

Option A: Renter-Friendly (Removable Mounting)

Perfect if you're renting or want the flexibility to remove it later.

  1. Get the right Command strips:
    • M6L-64 plate weighs 400-500g → Use 4-6 heavy-duty Command strips
    • M6L-85 plate weighs 600-700g → Use 6-8 heavy-duty Command strips
  2. Apply the Command strips:
    • Stick them to the back of the plate
    • Avoid covering the grounding strap area
    • Follow Command strip instructions (clean surface, press for 30 seconds)
  3. Position the plate:
    • Place directly opposite the external source (smart meter, transformer, etc.)
    • Press firmly against wall for 30 seconds
    • Wait 1 hour before moving to next step (adhesive needs time to cure)

Pro Tip: This method leaves zero damage when you move out. Perfect for renters.

Option B: Permanent Mounting (Screw Installation)

Best if you own your home and want maximum security.

  1. Mark your drill points:
    • Use the plate's mounting holes if pre-drilled, or mark corners
    • Double-check position before drilling
  2. Drill and mount:
    • Use wall anchors appropriate for your wall type (drywall anchors, masonry anchors, etc.)
    • Mount with screws, ensuring plate sits flat against wall
    • Don't: Overtighten screws (can warp the plate and reduce shielding effectiveness)
  3. Check it's flat:
    • No air gaps between plate and wall
    • Plate should not be bowed or warped

STEP 7: Install the Grounding Plate

The grounding plate should be installed near floor level, typically near an electrical outlet:

  1. Prepare the Grounding Plate Location:
    • Choose a location where the grounding strap from the shielding plate can reach
    • Near an electrical outlet is ideal (electrician will need access for earth connection)
    • Mark the position at approximately 10-20 cm above floor level
  2. Apply Additional Grounding Straps for Structural Support (Y-Shield Recommendation):
    • Apply one horizontal GSX strip (20-30 cm length) at the grounding plate location
    • Apply three vertical GSX strips (15-20 cm length) spaced evenly
    • These provide additional adhesive surface and ensure good electrical contact
    • The grounding strap from your shielding plate should contact these strips
  3. Mount the GS3 Grounding Plate:
    • The GS3 kit includes: aluminum plate (75x75x2mm), plastic cover (80x80x8mm), mounting hardware, and Torx® tool
    • Position the aluminum plate over the GSX grounding strap network
    • Secure with provided screws and dowels (use drill if required for wall type)
    • The plate height when mounted: 4mm (without lid) or 6mm (with lid)
    • Ensure the grounding strap from your shielding plate makes solid contact with the aluminum plate
  4. Attach the Cover Plate:
    • Snap the plastic cover over the aluminum grounding plate
    • The cover provides protection and a finished appearance
    • Do not yet connect electrical cables (that's the electrician's job)

STEP 8: Electrical Connection (Licensed Electrician Required)

This step MUST be performed by a licensed electrician in compliance with Australian electrical standards (AS/NZS 3000).

Electrician's Tasks:

  • Connect GL-series grounding cable (appropriate length) to the GS3 grounding plate terminals
  • Run cable to approved earth ground connection point
  • Verify electrical system is TN-S, TT, or IT type (not PEN-conductor system)
  • Confirm RCD/fault current circuit breaker ≤ 30 mA is installed on the circuit
  • Test ground continuity and resistance
  • Verify ground connection integrity with appropriate testing equipment
  • Document installation for compliance records

What NOT to Do (Safety Critical):

  • Never connect grounding to gas lines
  • Never connect grounding to water pipes
  • Never connect grounding to telephone or data lines
  • Never attempt electrical connections without proper qualifications
  • Never assume outlet ground is sufficient without testing

STEP 9: Verify Installation Performance

After installation is complete:

Immediate Verification:

  • Use your magnetic field meter to re-measure at the exact same locations as Step 1
  • Document the new measurements
  • Calculate the reduction: most successful installations show 75-98% reduction

Expected Results:

  • Professional installations typically achieve 20-33 dB attenuation (single layer M6L)
  • Even 15-20 dB (70-90% reduction) is considered excellent for home applications
  • If results are less than 50% reduction, check for:
    • Incomplete coverage (gaps in shielding)
    • Poor grounding connection
    • Very strong source requiring multi-layer shielding

Long-Term Monitoring:

  • Re-measure monthly for the first 3 months
  • Then quarterly to verify continued performance
  • Check grounding connections annually for corrosion or loosening

Step-by-Step: M2L/M2A Foil Installation

The thin foil materials (M2L and M2A) have different installation requirements than rigid plates:

STEP 1: Surface Preparation

  • Same as plate installation: clean, dry surface at 18-24°C
  • Foil can conform to curved surfaces (minimum 10mm bending radius)
  • Ideal for van walls, curved surfaces, and tight spaces

STEP 2: Cutting the Foil

According to manufacturer specifications:

  • M2L/M2A comes in 21cm width (23-24cm total with edges)
  • Cut with high-quality scissors - wear cut-resistant gloves (edges are very sharp)
  • For optimal shielding, plan seams with minimum 2cm overlap
  • Multiple layers increase performance (see multi-layer section below)

STEP 3: Installation Methods

Choose based on your application:

Method A: Adhesive Mounting

  • Use spray adhesive or contact cement suitable for the substrate
  • Apply adhesive to substrate (not the foil) for easier repositioning
  • Smooth out air bubbles working from center to edges
  • 10mm minimum bending radius allows following curves

Method B: Stapling/Nailing (Construction Applications)

  • Suitable for roof or floor constructions (manufacturer-approved use)
  • Use when installing as intermediate layer during builds
  • Staple or nail through laminated edges only (not through shielding surface)
  • Cover with construction materials per building codes

Method C: Sandwich Installation (Van Conversions)

  • Install foil between wall paneling and insulation
  • Ensure grounding strap extends outside the sandwich for connection
  • Allow 5-10mm clearance at mounting points to prevent vibration damage
  • Secure with construction adhesive to prevent shifting during travel

STEP 4: Grounding Foil Installations

  • Apply GSX grounding tape along one edge of the foil
  • For multiple foil strips, connect grounding tapes together
  • Run to single grounding point (GS3 plate)
  • Follow same electrical connection procedure as plate installation (licensed electrician required)

STEP 5: Multi-Layer Applications

For higher protection (high-flux environments), Y-Shield specifies:

Performance Data (M2L at 50 Hz Three-Phase):

  • Single layer: 12.1 dB (75.1% reduction)
  • Two layers: 16.3 dB (84.7% reduction)
  • Three layers: 19.5 dB (89.4% reduction)
  • Four layers: 21.7 dB (91.8% reduction)

Multi-Layer Installation Technique:

  1. Apply first layer and secure
  2. Create 2-5mm air gap (use thin spacer material or offset mounting)
  3. Apply second layer with seams staggered from first layer
  4. Overlap seams by minimum 2cm on each layer
  5. Ground each layer independently when possible
  6. Repeat for additional layers if required

Step-by-Step: Van Conversion Installation

Mobile applications have specific requirements due to vibration, space constraints, and electrical system differences.

STEP 1: Identify Shielding Priorities

Measure magnetic fields during:

  • Inverter operation under load (highest priority)
  • Shore power connection
  • Alternator charging
  • Battery system operation

STEP 2: Inverter Shielding

Distance First:

  • Position inverter as far as practical from living/sleeping areas
  • Install in dedicated compartment if possible
  • Maintain minimum 50cm distance from sleeping areas

Shielding Installation:

  • Use M6L-85 plates or M2L foil for wall between inverter and living space
  • Mount to van wall or build shielding partition
  • Ensure adequate ventilation - do not block inverter cooling vents
  • Leave 15-20mm clearance around inverter mounting points for vibration

STEP 3: Floor Shielding (During Build)

  1. Use M6L-9x roll material cut to fit floor area under sleeping platform
  2. Install over subfloor, under final flooring
  3. Leave 10-15mm clearance around all mounting bolts/studs
  4. Use construction adhesive to prevent movement during travel

STEP 4: Wall Shielding

  1. M2L or M2A foil works best for van curved walls
  2. Install between wall paneling and insulation during build
  3. For retrofit: position behind furniture/cabinetry
  4. Ensure grounding connections are accessible for inspection

STEP 5: Grounding in Mobile Applications

Van chassis grounding procedure:

  1. Remove paint at grounding point to expose bare metal
  2. Use ring terminals and stainless steel hardware
  3. Apply dielectric grease to prevent corrosion
  4. Multiple grounding points reduce ground loop potential
  5. Use star pattern grounding (all grounds to single main point, then chassis)
  6. Check connections quarterly - road vibration can loosen over time

STEP 6: Vibration Considerations

Critical for mobile installations:

  • Use lock washers on all mechanical connections
  • Apply threadlocker to screws in high-vibration areas
  • Check and re-tighten connections after first 500km of travel
  • Inspect grounding straps for wear or damage every 6 months

Quick Reference: Van Conversion Applications

Van and RV conversions present unique challenges due to space constraints, vibration, and high-current electrical systems. See the detailed Step-by-Step: Van Conversion Installation section above for complete instructions.

Key Considerations for Mobile Installations:

  • Inverters are typically the highest-priority magnetic field source
  • Use M6L-9x roll material for floor shielding during builds
  • M2L/M2A foil works better for curved van walls
  • Ground to chassis using bare metal connection points with ring terminals
  • Vibration-proof all connections with lock washers and threadlocker
  • Inspect grounding quarterly due to road vibration
  • Leave adequate clearance around mounting points

Quick Reference: Bedroom and Sleep Environments

Sleep is when your body performs critical repair and regeneration functions, making bedroom protection a high priority. See the detailed Step-by-Step: Home Wall Installation section above for complete installation instructions.

Pragmatic Bedroom Strategy:

1. Distance First (Costs Nothing):

  • Move bed 30-50 cm away from walls with smart meters or electrical panels
  • Unplug unused devices and extension cords
  • Remove or switch off electric blankets
  • Position clock radios and electronics at least 50 cm from head
  • This alone can achieve 50-75% reduction in many cases

2. Targeted Shielding (Where Distance Isn't Enough):

  • Install one M6L-64 plate behind bed if smart meter or transformer is on opposite wall
  • Shield only the wall area directly behind your sleeping position (typically 1-2 square meters)
  • You don't need to shield the entire room—focus on the 8 hours you spend stationary
  • For renters, use adhesive mounting (Command strips) for non-permanent installation

3. Verification:

  • Measure before and after installation
  • Most bedroom installations achieve 75-95% reduction in target areas
  • Even 70-80% reduction represents significant improvement
  • Remember: perfect is the enemy of good. Significant reduction is the goal.

Multi-Layer Applications for Higher Protection

In high-exposure environments (close to transformers, substations, or high-current installations), single-layer shielding may not provide sufficient protection. The Y-Shield materials are specifically designed for multi-layer applications.

Performance by Layer Count (M2L foil at 50 Hz):

  • Single layer: 12.1 dB (75.1% reduction)
  • Two layers: 16.3 dB (84.7% reduction)
  • Three layers: 19.5 dB (89.4% reduction)
  • Four layers: 21.7 dB (91.8% reduction)

Installation Tips for Multi-Layer Shielding:

  • Separate layers by 2-5mm of air gap or insulation material
  • Ground each layer independently when possible
  • Overlap seams by at least 2cm (20mm); 5cm recommended for best results
  • Stagger seam locations between layers

What Magnetic Field Shielding Won't Do

Let's be clear about limitations—this is important for setting realistic expectations:

Magnetic field shielding:

  • Will not create a "zero field" environment in typical home installations
  • Cannot completely eliminate fields from very strong nearby sources (major power lines, large transformers)
  • Does not shield against RF/wireless radiation (you need different materials for that)
  • Is not a substitute for smart electrical design and distance-based protection
  • Should not be seen as a way to live directly adjacent to high-exposure sources

What it will do:

  • Significantly reduce exposure (typically 75-95%) in targeted areas
  • Provide peace of mind and measurable protection
  • Enable you to live more comfortably in environments with unavoidable magnetic field sources
  • Complement distance-based strategies for comprehensive protection
  • Offer a practical, proven solution backed by testing and real-world results

Common Mistakes to Avoid

Don't let these common errors reduce your shielding effectiveness or create safety issues:

Mistake #1: Trying to DIY the Electrical Grounding

  • Why it's wrong: Illegal, dangerous, voids product warranty
  • Do this instead: Hire a licensed electrician (usually 30-60 minutes)

Mistake #2: Leaving Gaps in Coverage

  • Why it's wrong: Magnetic fields take the path of least resistance—gaps = reduced effectiveness
  • Do this instead: Overlap seams by at least 2cm, ensure continuous coverage

Mistake #3: Using Regular Scissors

  • Why it's wrong: They'll dull immediately and won't cut cleanly
  • Do this instead: Get high-quality scissors and cut-resistant gloves

Mistake #4: Not Measuring First

  • Why it's wrong: You might spend money on shielding when just moving your bed 30cm would solve the problem
  • Do this instead: Measure first, try distance-based solutions, then shield if needed

Mistake #5: Expecting 100% Reduction

  • Why it's wrong: That's not realistic—even professional installations achieve 75-98% reduction
  • Do this instead: Aim for significant reduction (75-95%), which makes a real difference

Mistake #6: Forgetting to Ground

  • Why it's wrong: Ungrounded shielding doesn't work as well AND can be unsafe
  • Do this instead: Complete the grounding (that's why you need the electrician)

Mistake #7: Blocking Ventilation

  • Why it's wrong: Shielding around heat sources (inverters) without airflow = fire hazard
  • Do this instead: Maintain clearance, don't block cooling vents

Safety and Installation Requirements

Electrical Safety (The Non-Negotiables):

  • Licensed electrician MUST do all grounding connections
  • Follow Australian electrical standards (AS/NZS 3000)
  • Never ground to gas lines, water pipes, or phone lines
  • Never attempt electrical work without proper qualifications
  • Electrician must test ground integrity with proper equipment

Installation Safety (Keep Yourself Safe):

  • These materials conduct electricity: Keep away from live electrical circuits during installation
  • Wear protection: Cut-resistant gloves when cutting, basic safety glasses
  • Follow the manual: Y-Shield provides installation guidelines—read them
  • Ventilation matters: Don't block heat-generating equipment (inverters, etc.)
  • Use good materials: Damaged or corroded shielding doesn't work—inspect before installing

In Plain English (Grounding): The shielding plate needs to be connected to the earth (like a lightning rod ground). This makes it work properly and keeps it electrically safe. An electrician connects everything to your home's existing grounding system—typically takes 30-60 minutes. This isn't optional; it's required by law and manufacturer specifications.

Measuring Your Results

The only way to know if your shielding installation is effective is to measure. We recommend:

Before Installation:

  • Document baseline measurements at multiple locations
  • Measure during typical usage periods (when appliances/inverters are operating)
  • Record measurements at head height for sleeping areas, seated height for living areas
  • Take photos and notes about measurement locations for consistent comparison

After Installation:

  • Re-measure at exactly the same locations
  • Calculate percentage reduction and dB attenuation
  • Typical successful installations show 20-30 dB reduction
  • Even 10-15 dB (90-97% reduction) is considered excellent for home applications

Cost-Effective Strategies for Getting Started

You don't need to shield your entire living space to make a meaningful difference. Here's how to prioritize:

Tier 1 - Highest Impact:

  • One M6L-64 plate for smart meter or primary exposure source
  • Basic grounding kit
  • Position behind bed or primary living area
  • Verify with measurements

Tier 2 - Bedroom Optimization:

  • 2-3 M6L-64 or M6L-85 plates for comprehensive bedroom coverage
  • Professional grounding system with proper cables
  • Cover primary walls adjacent to external sources

Tier 3 - Van Conversion:

  • M6L-9x roll material for floor installation
  • M2L foil for walls and curved surfaces
  • Inverter shielding with dedicated grounding
  • Multi-point chassis grounding system

Tier 4 - Comprehensive Home Protection:

  • Multiple rooms with targeted shielding
  • M6L-9x rolls for large-area coverage
  • Professional installation with licensed electrician
  • Full grounding system with multiple connection points

Common Client Scenarios

These are questions we get frequently from professionals and homeowners dealing with specific magnetic field challenges.

Scenario 1: Strata Properties with Basement Garage Smart Meters

The Situation:
Many modern apartment buildings and strata properties have smart meter banks installed in basement garages or ground-floor utility rooms. Living quarters (bedrooms, living rooms) are situated directly above these meter installations. Multiple smart meters operating simultaneously can create significant magnetic field exposure in the rooms above.

Why This Is Challenging:

  • Multiple smart meters in close proximity compound the magnetic field exposure
  • The floor/ceiling acts as the barrier between source and living space
  • Residents above may not realize the meters are directly below their bedroom
  • Electricians working on these installations need practical, tested solutions

The Solution:

For Electricians Installing Meter Banks:

If you're an electrician installing or upgrading meter banks in strata properties, here's the proactive approach:

  1. Plan for shielding during installation:
    • If building codes allow, install a layer of M6L-9x roll material on the ceiling of the meter room (below the residential floor)
    • Ensure 2-3 square meters of coverage beneath each residential unit above
    • Ground the shielding to building earth ground per AS/NZS 3000
    • This proactive approach costs far less than retrofitting later
  2. Recommended Products for Professional Installations:
  3. Installation approach:
    • Mount roll material to ceiling using construction adhesive or mechanical fasteners
    • Overlap seams by minimum 2 cm
    • Install grounding housing and connect to building earth ground
    • Document installation for building records and future residents

For Residents Living Above Meter Banks:

If you're already living in an apartment above a meter bank:

  1. Measurement first:
    • Use a magnetic field meter at floor level in bedrooms and living areas
    • Identify which rooms are most affected (meters may not be directly below every room)
    • Target shielding to specific high-exposure areas rather than entire apartment
    • Measure during peak usage times (meters under load)
  2. Floor shielding approach:
    • Install M6L-9x roll material under carpet or flooring in affected rooms
    • Focus on bedroom areas (you sleep there 8 hours—highest priority)
    • One 18-meter roll can cover approximately 14-15 square meters
    • Works for renters if installed under area rugs or removable flooring
  3. Renter-friendly options:
    • Cut M6L-9x roll material to fit under large area rugs
    • No permanent modifications required
    • Can be rolled up and taken with you when you move
    • Attach grounding strap and run to nearest outlet for electrician connection

Expected Results:

  • Properly installed floor shielding: 75-90% reduction in magnetic field exposure from meters below
  • Multi-meter installations may require two-layer shielding for optimal results (90-95% reduction)
  • Greatest improvement in rooms directly above meter concentrations

Materials Needed:

  • M6L-9x roll material for one bedroom (12-14 m²): one to two rolls
  • Grounding components (plates, straps, cables)
  • Licensed electrician for grounding connection

Pro Tip for Electricians: Including shielding in the initial meter bank installation adds minimal cost but provides significant value to residents. Consider offering this as an optional upgrade during strata electrical work.

Scenario 2: Bedroom Inverters, Wiring, and Switchboards

The Situation:
Modern homes and apartments sometimes have electrical switchboards, main distribution boards, or (in solar/battery installations) power inverters located on bedroom walls or in adjacent closets. This is particularly common in:

  • Townhouses and apartments with limited utility space
  • Homes with solar + battery systems (inverters near electrical panels)
  • Older homes where bedrooms were added near existing electrical infrastructure
  • Units where the electrical panel is in a "utility closet" backing onto a bedroom

Why This Is Challenging:

  • High-current electrical equipment operates 24/7
  • Bedroom exposure happens during sleep (8 hours of continuous exposure at close range)
  • These installations are often permanent and can't be relocated
  • Home buyers may not realize the issue until they measure or experience symptoms

The Solution:

Step 1: Measure Your Actual Exposure

Don't guess—measure first:

  • Use a magnetic field meter at head height in bed (where you actually sleep)
  • Measure with all circuits/inverters operating (worst-case scenario)
  • If readings are below 0.3 mG (3 nT): You may not need shielding
  • If readings are 0.5-3 mG or higher: Shielding is worthwhile
  • If readings are above 5 mG: Definitely shield, possibly multi-layer

Step 2: Try Distance-Based Solutions First

These cost nothing and often reduce exposure by 50-75%:

  • Move bed 30-50 cm away from the affected wall (this alone can be huge)
  • Reposition furniture so you're not spending extended time near the source
  • If inverter is in a closet, keep closet doors closed (minimal help, but every bit counts)
  • Use the bedroom only for sleeping, not as an office/workspace
  • Unplug or relocate any additional electronics from that wall

Step 3: Targeted Wall Shielding (When Distance Isn't Enough)

For Switchboards/Distribution Boards:

  1. Product selection:
    • One M6L-85 plate (80x55 cm) covers most standard switchboards
    • Position directly opposite the electrical panel (bedroom side of wall)
    • For large panels, use two plates with 2-3 cm overlap
  2. Installation approach:
    • Mount behind furniture if possible (hides the installation, looks cleaner)
    • For renters: Use heavy-duty Command strips (removable, no damage)
    • For homeowners: Screw mount for permanent installation
    • Complete grounding with licensed electrician (required)
  3. Expected results:
    • Typical reduction: 75-90%
    • Measurable immediately after installation

For Solar/Battery Inverters:

Inverters are higher-power devices and may need more coverage:

  1. Match shielding to inverter size:
    • Small inverters (1-3 kW): One M6L-85 plate usually sufficient
    • Medium inverters (5-8 kW): Two M6L-85 plates with 2-3 cm overlap
    • Large inverters (10+ kW): Consider M6L-9x roll material for full wall coverage or multi-layer installation
  2. Multi-layer for high-power inverters:
    • If single-layer shielding doesn't achieve adequate reduction (measure to confirm)
    • Install second layer with 2-5mm spacing between layers
    • Ground each layer independently
    • Expected performance: 25-33 dB attenuation (94-98% reduction)
  3. Installation priority:
    • Shield the wall section directly behind your sleeping position first
    • Expand coverage if needed based on measurements
    • Focus on head-height area (upper 1-2 meters of wall)

For Household Wiring in Walls:

  1. Identify problem circuits:
    • High-current circuits (electric ovens, AC units, heat pumps) create strongest fields
    • Aluminum wiring creates more magnetic fields than copper
    • Poorly balanced circuits or wiring errors can increase exposure
    • Very high readings may indicate a wiring fault—consult an electrician
  2. Shielding approach:
    • Use M6L-64 or M6L-85 plates for targeted areas
    • Focus on wall sections directly behind bed headboard
    • One or two plates typically sufficient for wiring-related exposure
    • Position at head height (where you sleep)

Product Selection Guide:

Situation Recommended Product Coverage Expected Result
Standard switchboard M6L-85 plate 0.44 m² 75-90% reduction
Small inverter (1-3kW) M6L-85 plate 0.44 m² 75-85% reduction
Medium inverter (5-8kW) Two M6L-85 plates 0.88 m² 80-95% reduction
Large inverter (10+kW) M6L-9x roll Custom cut 85-95%*
Household wiring M6L-64 plate 0.24 m² 70-85% reduction

*Multi-layer installation may be needed for very high-power inverters (10+ kW)

Complete Installation Requirements:

  • Shielding material (varies by application)
  • Grounding components (plates, straps, cables)
  • Licensed electrician for grounding connection

Expected Results by Application:

  • Switchboard shielding: 75-90% reduction typical
  • Small-medium inverter shielding: 80-90% reduction with proper coverage
  • Large inverter shielding: May require multi-layer for optimal results (90-95%)
  • Household wiring: 70-85% reduction in most cases

Real-World Timeline:

  • DIY mounting of shielding: 30-45 minutes
  • Electrician grounding connection: 30-60 minutes
  • Total time: About 1-2 hours from start to finish
  • Results are immediate and measurable

Pro Tips for Bedroom Applications:

  1. Measure in multiple sleeping positions: Exposure varies depending on which side of the bed you sleep on—measure both sides
  2. Consider both sleepers: If two people share the bed, measure on both sides; one person may need more protection than the other
  3. Verify with electrician first: If your home has very high readings (5+ mG), consult an electrician—there may be a wiring fault that needs correction
  4. Check building rules: In apartments/strata, verify whether wall modifications are allowed before mounting (or use removable Command strips)
  5. Photograph your measurements: Take photos of meter readings before and after for your records
  6. Don't over-engineer: Even 70-80% reduction is a significant improvement—you don't need perfection

Common Mistake to Avoid:
Don't assume "bigger is better" and over-purchase materials. Measure first, identify the actual problem area, and shield strategically. A single well-placed M6L-85 plate often outperforms excessive coverage in the wrong locations.

Frequently Asked Questions

Q: Can I just use aluminum foil or steel sheet from the hardware store?

A: Standard materials provide minimal magnetic field shielding. Y-Shield products use specialized high-permeability alloys specifically engineered for this purpose. The six-layer laminated construction of M6L products significantly outperforms standard steel or aluminum. Additionally, hardware store materials lack the weatherproofing, grounding connections, and safety features of purpose-built shielding products.

Q: How do I know if I need magnetic field shielding vs. RF shielding?

A: Use a dual-mode EMF meter that measures both magnetic fields (ELF) and RF. Identify your primary exposure sources:

  • Near power lines, transformers, smart meters, inverters = magnetic field shielding
  • Near Wi-Fi routers, cell towers, wireless devices = RF shielding
  • Many situations require both types of protection

Q: Will this affect my Wi-Fi or mobile phone reception?

A: The M6L series (magnetic field shielding only) will not significantly affect RF signals. The M2A dual-purpose foil will reduce RF signals, which is its intended purpose. If you need magnetic field shielding without RF reduction, use the M6L or M2L products.

Q: How long do these materials last?

A: Y-Shield products are laminated on both sides for long-term durability. In typical indoor applications, expect 10+ years of effective performance. In harsh outdoor or high-vibration environments (exterior walls, van conversions), inspect annually and replace if damage occurs.

Q: Can I cut the plates to custom sizes?

A: Yes. According to Y-Shield specifications, M6L plates can be cut with high-quality scissors (standard scissors will dull quickly). Important: Always wear cut-resistant gloves as cutting edges are extremely sharp. The M6L roll material can be cut to any size. Pre-sized plates (M6L-64, M6L-85) can also be cut, but cutting reduces the structural integrity of the lamination at edges. For best results, use appropriate pre-sized plates or order roll material for custom applications.

Q: What type of electrical system is required for grounding?

A: According to Y-Shield technical specifications, grounding is only permitted in TN-S, TT, and IT electrical network systems. Never install grounding in systems with combined PEN-conductors. Additionally, a residual current device (RCD) with ≤ 30mA trip current must be installed. If you're unsure about your electrical system type, consult a licensed electrician before purchasing. This is a safety-critical requirement.

Q: Do I need to ground every piece of shielding material?

A: For magnetic field shielding, grounding enhances performance and is recommended. According to manufacturer guidelines, you need one grounding point per continuous connected surface. For example, one bedroom wall would require one grounding plate (GS3), but if you're shielding multiple disconnected areas, each area should have its own grounding connection. The grounding must be installed by a licensed electrician.

Q: Can I install this myself or do I need a professional?

A: You can mount the shielding plates yourself using adhesive strips or mechanical fasteners. You can also apply the grounding straps to the shielding material. However, all electrical grounding connections to earth ground must be performed by a licensed/certified electrician according to Y-Shield safety requirements and Australian electrical standards (AS/NZS 3000). This is not optional—it's a safety requirement. Non-compliance can result in electric shock, severe injury, or fire.

Q: How do I know if my installation is working?

A: Use a magnetic field meter to measure before and after installation at the exact same locations. Professional installations typically achieve 75-98% reduction (15-30+ dB attenuation) depending on configuration. If you're getting less than 50% reduction, check for: incomplete coverage (gaps in shielding), poor grounding connections, or very strong sources that may require multi-layer shielding. Re-measure quarterly to verify continued performance.

Q: Can I use these products in outdoor applications?

A: The M6L series plates are fully laminated on both sides, making them suitable for outdoor use or as intermediate layers in roof/floor constructions. According to the manufacturer, they're "highly resistant, suitable as an intermediate layer in roof or floor constructions." However, grounding components have different requirements: GS3 plates are interior-use only, while GF3 grounding housings can be used outdoors with an additional seal. Always follow manufacturer specifications for each component.

Taking the Next Step

Magnetic field shielding doesn't have to be complicated, expensive, or overwhelming. Start with understanding your exposure, apply distance-based strategies first, then use targeted shielding where it makes the most sense.

The key principles to remember:

  1. Magnetic fields are not RF—they require different materials and different approaches
  2. Distance is powerful—the inverse square law means small increases in distance create large reductions in exposure
  3. Target your efforts—you don't need to shield everything, just the areas where you spend extended time
  4. Measure and verify—objective measurements ensure your efforts are working
  5. Professional installation matters—especially for grounding and electrical safety

Whether you're dealing with a wall-mounted smart meter, building out a van conversion, or optimizing your bedroom for better sleep, the Y-Shield magnetic field shielding products we carry provide proven, tested solutions backed by real-world results.
