EMF Shielding Australia: RF, Electric & Magnetic Fields
Share
If you are looking at EMF shielding for a bedroom, home office, nursery, smart-meter wall or window, the first question is not “what blocks EMF?” It is: what field am I trying to assess?
RF from Wi-Fi and mobile networks, low-frequency electric fields from voltage, and low-frequency magnetic fields from current do not behave in the same way. They are measured in different units. They also need different materials and installation methods.
Direct answer: Measure before buying where practical. Identify whether the issue is RF, a low-frequency electric field or a low-frequency magnetic field. Start with room layout and distance, then choose a product that is designed for that specific field type. Fixed conductive systems need a proper grounding and electrical plan. No single fabric, paint or meter is the right answer to every situation.
Start with the question you actually have
Schild's room-by-room home guide and DIY guide repeatedly centre on bedrooms and nurseries, home offices and Wi-Fi, smart-meter walls, wiring, appliances and windows.
Its existing smart-meter guide and meter comparison also show that first-time measurement and meter selection are core reader decisions. Use the route below rather than reading the whole guide from top to bottom.
| If your question is… | Start here | Likely next product conversation |
|---|---|---|
| “I want to understand what is present in this room.” | Measure first and map the room | TriField TF2 for broad household RF, electric and magnetic modes. |
| “Is this a Wi-Fi, phone, Bluetooth or other wireless issue?” | Read the RF section and compare the same location before/after a layout change | Start with Safe and Sound Classic III or Safe and Sound Pro II, then adjust device placement or move to a suitable flexible RF material only if the relevant path is understood. |
| “My bed, cot or desk is against a smart-meter or electrical-panel wall.” | Map the wall, move furniture where practical and measure the relevant field category | HSF54 for an assessed RF/electric-field wall treatment; M2A only for a defined magnetic-field requirement. |
| “I am looking at a window, curtain, canopy or temporary divider.” | Work out whether the pathway is RF or a low-frequency electric-field treatment | Swiss Shield Naturell Ultra, SLNT fabric or Leblok Silver SuperShield, depending on the installation approach. |
| “I rent and do not want a permanent installation.” | Start with layout, measurement and a reversible material trial | SLNT fabric or another suitable flexible material, without altering fixed wiring or utility equipment. |
| “I am renovating and want a proper wall system.” | Read the fixed-system and grounding sections before ordering materials | HSF54 or M2A, with installer-designed bonding/grounding where appropriate. |

The three field types that matter at home
“EMF” is an umbrella term. In a home, three categories usually drive the practical choice of meter or material.
| Field type | What creates it | Common units | Common home sources | What it means for shielding |
|---|---|---|---|---|
| RF / radiofrequency | Wireless transmission | µW/m², mW/m² or V/m | Wi-Fi, mobile phones, Bluetooth, cell towers, wireless smart meters | Conductive fabric, mesh, canopies and shielding paint can be relevant, depending on coverage and installation |
| Low-frequency electric field | Voltage | V/m | Building wiring, outlets, switches and connected electrical equipment | Conductive shielding materials may be relevant when correctly bonded/grounded |
| Low-frequency magnetic field | Current flow | µT or mG | Wiring under load, switchboards, transformers, inverters, appliances and electrical equipment | Requires a purpose-designed magnetic shielding material; ordinary RF fabric or paint is not automatically the answer |
RF: the wireless part
Radiofrequency electromagnetic energy (RF EME) is used for wireless communication. ARPANSA defines RF EME as radio-wave energy between 100 kHz and 300 GHz. Wi-Fi, Bluetooth, mobile networks, wireless smart meters and broadcasting are all RF sources, but their frequency, transmission pattern and power are not the same.
A meter can help compare one location with another, but it has limits. ARPANSA explains that common broadband RF meters show the combined RF in an area and cannot assign a reading to one individual source such as a smart meter or Wi-Fi router. Source-specific work requires specialised equipment and technical expertise.
Low-frequency electric fields: voltage-related
Australia uses 50 Hz alternating current. ARPANSA and ICNIRP explain that low-frequency electric and magnetic fields are associated with electricity generation, distribution and use at 50 Hz in Australia. The electric field is associated with voltage and is measured in volts per metre (V/m).
Electric fields can be associated with live wiring and electrical equipment. If a conductive wall system is selected to address that category, the bonding and grounding arrangement is part of the installation, not an optional accessory.
Low-frequency magnetic fields: current-related
Magnetic fields are associated with current flow. They are usually expressed as microtesla (µT) or milligauss (mG), where 1 µT equals 10 mG. ARPANSA's electricity guidance explains the distinction between voltage-related electric fields and current-related magnetic fields.
This distinction matters because a conductive RF fabric or shielding paint is not automatically a magnetic-field shield. For low-frequency magnetic fields, the material needs to be designed for that field type. In this guide, that means a specialist product such as YSHIELD M2A magnetic-field shielding foil, not a generic RF layer.
What Australian standards do and do not say
There is no single “EMF standard” that applies to every field.
RF: ARPANSA RPS S-1
The relevant Australian RF standard is ARPANSA's RPS S-1 (Rev. 1), Standard for Limiting Exposure to Radiofrequency Fields – 100 kHz to 300 GHz. It applies to RF EME for the public and workers. It is the correct framework when discussing wireless sources such as Wi-Fi, mobile networks and a smart meter's RF communication.
Low-frequency electric and magnetic fields: ICNIRP 2010
For low-frequency electric and magnetic fields, ARPANSA points to the ICNIRP 2010 Guidelines for Limiting Exposure to Time-Varying Electric and Magnetic Fields (1 Hz–100 kHz). For the general public at 50 Hz, the reference levels are 5 kV/m for electric fields and 200 µT (2,000 mG) for magnetic fields.
Those figures are assessment reference levels. They are not a shopping target, an individual wellness target or a promise about how a room will feel after a product is installed.
What standards cannot tell you from a single reading
A standard does not make a consumer meter into a compliance instrument. It also does not mean a dB figure on a product page predicts the exact result in every room.
Room geometry, wall materials, windows, gaps, frequency, distance, the number of active devices and the quality of installation all affect real-world results. A careful guide should say that up front rather than turning one number into a guarantee.
Measure first: choosing an EMF meter
The most useful first purchase is often a meter, not a shielding material. It helps you establish a baseline, identify what category you are looking at and test whether a change altered the same location.
Which meter should you choose?
| Product | Use it when | It measures | Important limit |
|---|---|---|---|
| TriField TF2 | You need one broad household tool | AC magnetic, AC electric and RF/microwave modes; Peak Hold is listed for brief signals | Its RF mode measures the total RF environment, not one source alone, as ARPANSA explains. |
| Safe and Sound Classic III | You want a simple RF-focused first check | RF detection across 200 MHz–8 GHz; Schild lists smart meters, Wi-Fi, Bluetooth and phones among potential sources | It is not a magnetic-field meter and does not isolate one RF source. |
| Safe and Sound Pro II | You want more detailed RF readings, Max Hold and an OLED display | RF detection across an effective 200 MHz–8 GHz range; the product page lists digital readings and Max Hold | It remains an RF meter, not a meter for low-frequency magnetic fields. |
A repeatable baseline method
- Mark the places that matter: pillow position, cot, desk chair, sofa, window or wall.
- Write down the exact location, height, distance from the wall, meter model and meter mode.
- Note nearby sources that may be operating, such as Wi-Fi, phones, Bluetooth equipment or appliances.
- Take readings at the same locations at more than one time where practical.
- Change one thing at a time, then repeat the same measurement points.
This approach is more useful than chasing a single peak reading. It lets you compare before and after without pretending the meter has identified a source it cannot separate.
The practical shielding order: solve the right problem first
A strong shielding plan usually follows this order.
1. Map the source and the room
Start with layout. Are you dealing with a router next to a desk, a bed against a meter wall, a window facing an external RF source, wiring behind a headboard, or a fixed electrical panel?
ARPANSA recommends that people concerned about sleeping next to a meter box consider moving the bed away, typically more than one metre, and measuring actual magnetic-field levels in the room. That is a practical first move, not a universal rule.
2. Use distance and layout before a major installation
Move the bed, desk or couch where the room allows. Move a router away from a working or sleeping position. Turn off or relocate one obvious device at a time if you are trying to understand a reading.
Distance does not solve every case, especially where a fixed wall, window or electrical installation is the issue. It is still the simplest variable to test before buying material.
3. Match the material to the field
- RF question: choose an RF-capable fabric, canopy, curtain, mesh or paint.
- Low-frequency electric-field question: choose a conductive solution that is designed and installed with the required bonding/grounding.
- Low-frequency magnetic-field question: choose purpose-designed magnetic shielding, not ordinary RF paint or fabric.
4. Verify the result
Re-test the same location. For a fixed conductive installation, include the electrician or installer in the verification plan. The aim is a documented, sensible installation, not a vague claim that the room has been “protected”.
Product guide: core Schild products and their use cases
This is the product map for the guide's core jobs: measurement, fixed wall shielding, flexible RF shielding, magnetic-field shielding and grounding components. It intentionally does not duplicate sizes, samples, care products, clothing, phone accessories or unrelated Faraday products where they do not change the reader's decision.
Meters: start here when you do not yet know the field type
| Product | Best use case | Why it fits | Do not use it as |
|---|---|---|---|
| TriField TF2 | General home assessment: walls, appliances, wiring, smart-meter walls and routers | Covers AC magnetic, AC electric and RF/microwave modes in one unit | Proof that one RF source alone caused the reading. |
| Safe and Sound Classic III | Simple RF comparison around a router, wall, smart meter or wireless device | RF detector with 200 MHz–8 GHz range listed by Schild | A magnetic-field or electric-field meter. |
| Safe and Sound Pro II | More detailed RF comparison, with digital readings and Max Hold | Adds OLED display, Max Hold and listed 200 MHz–8 GHz effective measurement range | A source-specific compliance assessment. |
Fixed wall systems: RF and low-frequency electric fields
| Product | Best use case | What it is designed for | Key installation boundary |
|---|---|---|---|
| YSHIELD HSF54 shielding paint, 1 L | Small, defined inside-wall test or treatment area | High-frequency shielding and low-frequency alternating electric fields | Conductive surface must be integrated into functional equipotential bonding. |
| YSHIELD HSF54 shielding paint, 5 L | Larger planned wall, room or renovation project | Same field category as the 1 L format, with more material for larger coverage | Not a low-frequency magnetic-field shield; fixed conductive work needs a qualified plan. |
| Swiss Shield Naturell Ultra fabric | Window curtains, wall curtains or a canopy where you want a textile rather than paint | Schild lists it for RF/microwave shielding and, when grounded, low-frequency electric-field shielding | It is conductive and groundable; do not treat it as an ordinary ungrounded curtain or a magnetic-field shield. |
| SLNT Silent Faraday MULTISHIELD fabric | Flexible RF-oriented divider, temporary barrier or DIY Faraday project | Schild lists it for cellular, Wi-Fi, Bluetooth, GPS, RFID and other RF applications | It is not a purpose-designed low-frequency magnetic-field shield. |
| Leblok Silver SuperShield material | Curtains, screens, canopies and flexible RF barrier projects | Product page lists 50 dB at 1 GHz, conductive construction and use in curtains, canopies and screens | Product performance is not a whole-room guarantee; installation geometry and coverage matter. |
| YSHIELD SAFECAVE single-bed popup | A defined sleeping-space RF and electric-field textile application | Product page lists high-frequency shielding and low-frequency alternating electric-field shielding with grounding accessories sold separately | It is a personal textile enclosure, not a solution for low-frequency magnetic fields or an electrical-installation issue. |
DIY RF product
| Product | Best use case | What it is designed for | Key installation boundary |
|---|---|---|---|
| MISSION DARKNESS TitanRF Faraday Fabric Pack | A small DIY RF enclosure, test project or device-isolation application | Product page lists copper/nickel construction and RF attenuation testing, including wireless-signal isolation applications | It is a flexible RF material, not a general low-frequency magnetic-field solution or a substitute for a fixed-building design. |
Purpose-designed magnetic-field shielding
| Product | Best use case | What it is designed for | Key installation boundary |
|---|---|---|---|
| YSHIELD M2A magnetic-field shielding foil | Defined wall, equipment or construction detail where low-frequency magnetic fields and high-frequency shielding both need consideration | Product page lists low-frequency magnetic-field attenuation and high-frequency attenuation | Use a competent design for coverage, overlap, joins and grounding. Do not substitute paint or ordinary RF fabric for this job. |
Grounding components: part of the system, not stand-alone remedies
| Product | Best use case | What it does | Important boundary |
|---|---|---|---|
| YSHIELD GSX10 grounding strap | Bridging conductive paints, fleeces or nettings within a fixed installation | Self-adhesive conductive strap listed for use under or on conductive shielding materials | It is an installation component, not a substitute for a qualified grounding design. |
| YSHIELD GS1 grounding plate | Interior fixed shielding products and grounding straps, commonly at skirting-board level | Schild lists it for installation on shielding products and grounding straps | Cable and electrical connection need to be selected as part of the fixed-system plan. |
| YSHIELD GCM grounding connection magnet | Conductive fabrics, fleeces and meshes where perforating the material is undesirable | Magnetic plates hold the conductive material between them for one cable connection | Use only in an appropriate grounding system for that material. |
| YSHIELD GPI grounding plug | Portable textile products such as canopies, bedding and earthing products | Schild lists it for portable textile products | Schild explicitly says it must not be used to ground fixed shielding products such as paints, meshes, fleeces, plaster or reinforcement fabric. |
Grounding fixed systems and portable textiles
Grounding is one of the areas where a general guide can do more harm than good if it turns into a plug-and-play instruction.
For fixed conductive wall systems, the manufacturer requirements matter. Schild's HSF54 instructions require functional equipotential bonding for the conductive surface. The M2A foil page specifies grounding for its conductive surface. That makes the electrical plan part of the installation, alongside material choice, overlap, wall construction and placement.
Portable textiles are different. Schild's GPI grounding plug is for portable textile products, and its page explicitly excludes fixed shielding products. That is why the guide does not tell readers to connect paint, mesh or foil to a generic plug.
A qualified electrician or competent installer should decide the fixed-system bonding and grounding arrangement. They should work from the product instructions, the building's electrical arrangement and applicable electrical requirements. The reader's job is to identify whether the product is fixed or portable, and to avoid mixing those systems.
Electrical work notice: This guide is general information, not electrical advice. Do not alter fixed wiring, meter panels, switchboards or grounding yourself. Any electrical work must be assessed and carried out by a licensed electrician. Schild cannot accept responsibility for damage caused by unqualified work.
Common scenarios: what to do first
Smart meter on the other side of a bedroom wall
ARPANSA explains that smart meters use short bursts of RF EME to communicate with the energy supplier. The nearby electrical system can also involve low-frequency electric and magnetic fields. Measure inside the room, map the bed position and move the bed away from the wall where practical. Then choose an RF/electric-field wall material or a purpose-designed magnetic product only after identifying the field category.
Do not cover, wrap, alter or access the meter itself. Work from the inside wall and keep utility equipment accessible.
Wi-Fi router, phone or wireless device near a desk
Start with a broad RF comparison. The Safe and Sound Classic III or Pro II can help compare RF activity at the desk versus a moved-router location. If you want a flexible RF barrier for a particular window, screen or canopy application, look at fabric products before considering permanent wall work.
Window facing an external RF source
First measure at the window and where you sit or sleep. A curtain-style product may be more relevant than paint if the window is the path you are assessing. Swiss Shield Naturell Ultra and Leblok Silver SuperShield are both listed for flexible curtain/screen-style applications, with different material and grounding characteristics.
Wiring, switchboard, inverter or appliance concern
Use the TriField TF2's magnetic and electric modes to map the location first. If the concern is low-frequency magnetic fields, do not assume RF fabric or shielding paint will solve it. A fixed electrical issue, unusual reading or installation decision may need an electrician or qualified assessor before a shielding material is chosen.
Frequently asked questions
What is EMF shielding?
EMF shielding uses a material or installation method to reduce a particular electromagnetic field in a defined location. The correct material depends on the field: RF, low-frequency electric fields and low-frequency magnetic fields require different approaches. A shielding product should be chosen for the field category and installed as its manufacturer specifies, not treated as a universal solution.
Does EMF shielding work?
A shielding material can attenuate the field it is designed and installed to address, but the result depends on the field type, frequency, coverage, gaps, wall or window construction and installation. Measure the same location before and after a change where practical. Do not use RF fabric or shielding paint as a substitute for a purpose-designed magnetic-field solution.
What is the best EMF shielding product to buy first?
Usually, start with a meter rather than a shielding material. The TriField TF2 is the broadest option in this guide because it covers RF, AC electric and AC magnetic modes. Once you know the field category and the place you want to assess, choose the material for that job rather than buying a generic “EMF blocker”.
Does shielding paint block magnetic fields?
Not automatically. YSHIELD HSF54 is listed for high-frequency fields and low-frequency alternating electric fields. Low-frequency magnetic fields need a purpose-designed magnetic shielding material, such as the M2A foil category, when assessment and installation planning call for it.
Do I need to ground shielding paint or conductive foil?
For fixed conductive products, grounding or bonding is part of the system. Schild's HSF54 page specifies functional equipotential bonding, and the M2A page specifies grounding. Use a qualified electrician or competent installer to determine the arrangement. Do not use a portable-textile grounding plug for fixed paint, mesh or foil.
Can I use a meter to identify a smart meter, Wi-Fi router or phone separately?
A consumer broadband RF meter can measure total RF in an area, but ARPANSA says it cannot assign that reading to one individual source. Source-specific measurement needs specialised equipment and technical expertise.
Which product works best for a window or bed canopy?
For a textile approach, Swiss Shield Naturell Ultra is listed for wall/window curtains and canopies, with RF shielding and, when grounded, low-frequency electric-field shielding. Leblok Silver SuperShield is listed for curtains, screens and canopies. Choose based on the physical installation, field type and whether the product is fixed or portable.
What should I do before adding shielding to a rental?
Begin with layout changes and measurement. Use a temporary or flexible product only where it is appropriate to the field type and does not interfere with utility equipment or fixed electrical systems. Do not make a permanent conductive installation or grounding modification without landlord permission and qualified electrical advice.
The practical next step
Do not start by trying to shield an entire house. Start with the place that matters most: a bed, desk, cot, sofa, window or shared wall. Measure it. Identify the field category. Change the simplest variable first. Then choose the product whose field type, installation method and grounding requirements match the job.
That is how you build a shielding plan that is useful, testable and proportionate.
