How to shield and protect a home from cell phone tower RF radiation.
Part 2
Following on from Part 1 where we questioned whether shielding a home from a cell phone tower is necessary, let’s cover how we do actually shield a home but please do read the first part of this series.
If you are in the unfortunate position of having a cell phone tower influence your home, know that it is possible to shield a room, multiple rooms or even the entire house front the unwanted radio frequency radiation or RFR.
Firstly, having RFR from multiple cell tower transmitters affecting and influencing a bedroom or other room where you spend time will have a detrimental effect. To what degree, that is uncertain and is determined by many other factors including your environment, health, habits, population density etc. Normally I would dance around the subject saying floppy words like ‘may have an effect’ or ‘likely to have an effect’. But to be straight, the effects of RFR exposure are all very real and extremely well documented. The NZ government deflects its responsibility by relying on overseas standards which are far too inadequate and bear no resemblance to real world everyday exposure. Back in 1996 when the standards where established it may have been true to some small degree in a 1G and 2G world, but in this modern age of RF saturation, it absolutely doesn’t reflect the exposure many people experience. I have written about this in other blogs so won’t cover the details here.
Shielding a home
So how do we shield a house or part of a house from a cell phone tower or individual transmitters?
First of all, the source of the problem has to be measured to understand the size and scale of the issue, which areas it affects, what surfaces need to have protection for best results and indeed, if shielding is appropriate in the first place. Refer to Part 1 of this series where we discuss when shielding may not be required.
When shielding is required, and the area of the home identified, let’s say it is the master bedroom at the front of a house. Here is how we do it.
And also for reference from a personal standpoint, I have half of my own house shielded covering walls, windows and curtains which is documented here. https://www.emfshop.co.nz/how-to-shield-a-home-from-emf
WALLS
Shielding walls is done with shielding paint (hard surfaces are generally painted). The paint is a special graphite based paint which is conductive and this is what gives it its shielding properties. YShield is the main brand.
Typically two coats are required for all walls exposed to the source of the RFR. This includes the ceiling and floor (where the room is elevated from ground level). Where cell phone transmitters are very close to a home, let’s say 50 metres, three coats would be recommended. While two coats would be sufficient adding another coat is to future proof as the power output of cell transmitters is very often turned up when licenses expire and are reissued. Also more transmitters are also likely to be attached to existing structures as recent law changes suggest.
The shielding paint is a powder so needs mixing with water which is very easy to do. Being graphite means it is also black so the area will need your normal colour paint over the top. The paint can be used internally or externally. In my case I painted the outside of the house. The main tip when using the paint is to remix every 15 mins or so as heavy particles settle and cause clumping.
As the paint is conductive, it needs to be earthed. As a general rule, only on walls where electric circuits are present in the structure, but good practice is to earth every painted surface. This is for electrical safety and from an EMF standpoint, it grounds any electric fields that are present reducing their broadcast effect.
Earthing a painted surface is achieved by using conductive tape (also known as a grounding strap) applied around the edges of the painted wall, this then attaches to a grounding plate which leads to either a separate grounding rod (conductor) or to an electrical outlet where your electrician will join it to the house earth wiring. A simple conductive test with a multimeter will show the appropriate connection across the paint, tape and ground.
The process is, one coat of paint, place down conductive tape, apply second coat of paint.
The paint needs to be continuous across all surfaces so it creates one big coating. The paint needs to cover up to window frames and in high RFR situations, window frames will need to be painted also especially if they are made of wood.
What about lead paint?
Yes, the old lead paint would have been excellent as a shielding paint so if your home still has lead paint, understand that removing it will open up your home to RF if a cell tower is close by.
FLOOR
If the floor needs to be shielded, here we use RF shielding material https://www.emfshop.co.nz/product-page/radio-frequency-shielding-material.
A ground floor with no basement wouldn’t need shielding, so this method is for floors not at ground level.
This materials comes in 1m widths and is cut to length. One layer placed either under the carpet or a large rug with at least six inches of taped over lap. If you have access to the floor joists this material could be stapled in there. No earthing required but is recommended.
WINDOWS
To shield windows that let in radiation from a cell phone tower, there are three options.
1. Window shielding film. https://www.emfshop.co.nz/product-page/window-film-rf-emf-protection-by-solargard
This is a dedicated RFR shielding material specifically designed for windows and requires professional installation (unless you want to install it yourself). It works very well and provides both day and night protection.
2. Shielded net curtain. These net curtains while they cover the area around the window, still provide an amount of light during the day and a good level of protection, but not as good as the window film. The net fabric is woven generally with silver fibre. Swiss Shield are considered the best material out there, but pricey. Other net fabrics with silver are also very good https://www.emfshop.co.nz/product-page/net-cotton-rf-shielding-fabric-shieldplus. Price can move up and down as silver prices change. This solution serves both for day and night time.
3. Shielding curtains. Using the RF shielding material we used for the floor, we can place this (stitch or pin) inside your curtain lining in between the thermal backing and the curtain material. This is the solution we have adopted at home on one of the windows (other windows we have used the film).
This option works very well when the curtains are drawn but essentially only becomes a night time solution if curtains are opened during the day.
For added shielding benefits any combination of all three would be highly effective. Recognising that window film is semi permanent and the other two options can be removed and used elsewhere if you ever move house. No grounding coupling is required for window or curtain solutions.
FARADAY BED CANOPY
Faraday bed canopies are very effective. They look like a mosquito net and attach to the ceiling and drape over a bed. I recommend these as an initial almost emergency solution. If a high source of RF like a cell phone tower is installed and immediately affects your bedroom, your go to quick solution is to install a bed canopy. Use it as either a permanent solution or temporary while you work out and apply other shielding techniques. Faraday bed canopies come with an earthing point and need connecting to ground. Easily done with a plug and cable.
Shielding a room means changing habits
Any application of shielding to a living space, room or house requires a change in habits. What we mean by this is, a shielded house becomes more conductive and so whatever broadcasts inside, will be reflected and concentrated inside the shielded areas. Elimination of other RF broadcasting sources needs to be added to the list of things to do. Make a checklist of every device that connects to WiFi or transmits Bluetooth and disable or remove. Recognising that the use of a mobile phone inside a house will become difficult and a phone will emit more RF radiation than normal searching for the lost signal. Take cell phone calls outside the shielded areas. It is also useful to tell visitors the situation so they also avoid adding to any inside RF.
Other habits to be aware of are for outside, with cell phone tower RF radiation looming over your house this also means when you go outside you are in a higher level of exposure. Consider where possible avoiding being near the tower, drive or walk in different directions, consider wearing a shielding cap (only near the tower). This of course becomes challenging in warmer months when we want to spend time outside. Some outside shielding options are available depending on the location and proximity to the cell tower and may require a bit of a DIY job to make. For instance at my own house, sitting outside on the deck means exposure to a local direct line of sight cell phone tower, so here I have made two large wind breaks that are backed with fine wire mesh. They work extremely well and give peace of mind when sitting outside, as I was half an hour ago. We have planted the area but bushes need time to grow so the shielded wind breaks are ideal.
Final word
In just about all instances, it is possible to shield the essential areas of a house from RFR. However, in some circumstances, certainly in high population areas in cities while shielding will provide some respite, looking at the bigger picture as cell towers and number of transmitters are expanding markedly, the strength of the radio frequency and layers of RF are also increasing quickly. Understanding this, if health is your primary motivator, then sometimes we have to make the hard calls and move house.
At the time of writing this in November 2026, the mainstream news reflects that 3500 or more new cell phone tower sites will be installed over the next few years. Preparing ourselves for this is a must, future proofing a home is now critical. Learning more about cell tower radiation and EMF in general is essential.
Rise above and ignore the naysayers, but watch and observe them closely for they are the canaries in the coal mine.

This is called capacitative coupling or in the EMF world parasitic coupling. Electric fields jump conduct onto other conductive surfaces.
