The sun is shining, and you want to let that natural light in. But what if you are concerned about EMF radiation? Whole-house protective measures may be reducing the amount your home produces, and you may even be using protective paint or wallpaper and curtains to block out some outside sources of EMFs. When the windows are open, however, it’s not just sunlight that is getting through.
It may seem like a life with the curtains drawn is the only solution. In reality, however, you can have your cake and eat it, too. How so?
EMF protection window films.
These films go over your window, allowing sunlight to penetrate through while reflecting back a large percentage of EMF radiation. Whether you are concerned about long-term damage to your family’s health or you suffer from a condition such as Electromagnetic Hypersensitivity, if you are serious about reducing your EMF exposure, protective window film is a must-have item.
There are a variety of EMF protection films out there. If you have sensitive eyes, you may find yourself drawn to tinted options. Or, if you want to let in as much sunlight as possible, there are clear versions, as well. Indeed, being EMF-conscious and reducing your exposure doesn’t have to mean missing out on natural lighting.
In this guide, we will dive into some of the protective films on the market today. We will also give tips for applying your film, and talk about how you can test your film’s effectiveness after application.
Top EMF protection window films of 2020
6. Amradield Nickel Copper Window Gauze. This mesh fabric from Amradield allows a decent amount of sunlight through while keeping EMF radiation out. Able to attenuate frequencies ranging from 30MHz to 8GHz, the gauze is made from a blend of copper, polyester, nickel, and silver. It is easy to work with, conductive, and anti-static. You can purchase Amradield’s gauze in 43-inch wide strips that are either 197-inches, 39-inches, or 78-inches long, depending on the size you need.
5. Blocfilm EMF Protection Window Film Blocbronze. Blocfilm’s protective window film in Blocbronze has been tested and shown to be effective at shielding against frequencies up to 10GHz. It provides superior EMF protection in addition to privacy, as the Blocbronze color allows some sunlight to penetrate through while making it difficult to look into your window from the outside. Sheets are available in several different sizes, from 5-feet by 5-feet all the way up to 20-feet by 5-feet, so no matter how many windows you have, Blocfilm has you covered.
4. Blocfilm EMF Protection Window Film Tinted. If you loved the sound of Blocfilm’s protective film but aren’t so sure about the bronze color, you’re in luck. The manufacturer also makes their film in a tinted clear color, allowing for even more sunlight to penetrate through. It may not have all the privacy protections, but it is still highly effective up to 10GHz.
3. LessEMF RadioFilm. This window film from LessEMF is completely transparent, so if your goal is to let as much sunlight in as possible, this is an excellent choice. It’s so clear you can even use it on your TV screen, but for our purposes, we’ll focus on it as a window film. This material is quite effective at shielding against EMF radiation and comes in 12-inch wide strips. It is available either by the foot or in a 100-foot roll if you have a lot of windows to cover.
2. Safe Living Technologies Signal Protect Clear Film. Safe Living Technologies’ window film transmits 72% of sunlight through while still shielding against 99.99% of outside RF-EMF radiation. It’s not as reflective as some other window films, making it a little more discreet and easier to see through, as well. This film can even help keep out solar heat, ultimately leading to lower utility bills during the warmer months. Made to protect against both RF-EMF and microwave radiation, Safe Living Technologies’ window film is ideal for any room. This item is sold in five-foot-long increments that are either three, four, or five feet wide.
1. EMRSS High-Frequency EMF Shielding Window Film. Made for glass surfaces such as windows, this high-frequency EMF shielding film from EMRSS is 99.94% effective against frequencies up to 1Ghz. Each roll is approximately 2.5-feet wide by 3-feet long and it contains 12 different metal layers. In spite of that, the window film still allows for 72% light transmission. It’s worth noting that this film requires a special adhesive to apply, which is sold separately. The manufacturer recommends that FKV50 Edge Sealant is used to seal the film’s edges, providing a secure fit that will keep the maximum amount of EMF radiation out.
Tips for applying your window film
The process for applying your new window film is generally the same, regardless of which option you choose. The very first step is to give your window a good and thorough cleaning. Remember, you’re going to be placing a film over the glass, so unless you want those smudges from your dog’s nose to live on in infamy forever, it’s a wise idea to wipe them off prior to applying your film. Likewise, any dust or debris will be trapped under your film and potentially weaken the bond of the adhesive to the glass. Using your preferred window cleaning solution and a cloth or newspaper, spray down your window’s glass and wipe it down using a circular motion to prevent streaking. Wait for the window to dry and make sure the glass is as clear as it can be before continuing. If any smudges remain, repeat the cleaning process.
Next, you will need to measure your window. Measure the length and width of each panel of glass, and then add a half-inch or so to those measurements. That way, you will be able to ensure a completely secure fit, and you can always trim off any extra film that is leftover. Use scissors, a knife, or another cutting tool to cut your window film to the appropriate size.
Most window films on our list are self-adhesive films. This means they are essentially like a sticker — you simply need to peel off the layer of protective paper on the back to reveal the adhesive. Once the paper has been peeled away, carefully and evenly apply the film, adhesive layer down, to your window. In the case of Amradield’s gauze, the manufacturer includes tape you can use to apply the material to your window. Or, if you are using RadioFilm, you may need to purchase your own adhesive tape, such as TitanRF Faraday Tape.
As you apply the window film, if any air bubbles appear, you can use a smoothing tool to press them out. Rust-Oleum’s Flexible Smoothing Tool is one great option for smoothing.
Repeat this process for each window you wish to cover in EMF protection film. The hardest part is really smoothing out the air bubbles, and once you get that down, it goes pretty quickly.
Testing your EMF protection window film
The main thing you need to test your EMF protection window film is a solid EMF meter. Ideally, it should be capable of measuring radio frequencies, electric fields, and magnetic fields. If you don’t already have one, our guide to The Best EMF Meters For Any Budget can help point you in the right direction.
Prior to applying your film, take a base measurement near the window and at various distances away from it. Repeat this process for each window you plan on covering. This gives you an idea of how much EMF radiation is entering through that point. Of course, your home’s other sources of EMF radiation are also factored into this measurement, but this at least gives you a point for comparison.
After applying your protection film, re-take your measurements. Try and take them from the same distance away from the window as your baseline measurement, for the most accurate results. Then, compare the levels. If the window film is doing its job, your meter will pick up a great deal less EMF radiation after the protection film is installed.
If you are looking for a way to prevent EMF radiation from entering your home, it’s worth it to consider applying EMF protection window film. This film allows you to let natural sunlight in without sacrificing your family’s safety. Your budget and the number of windows in your home can help you decide exactly how many windows to cover. At a minimum, it is recommended to at least cover windows in high-traffic areas such as the living room and home office. Rooms where you don’t spend a lot of time during the day are not as much of a priority, but could still help reduce your home’s overall EMF levels.
If your goal is to significantly reduce the amount of external EMF that enters your home, it is also advisable to invest in anti-radiation curtains. You may also want to cover walls in high-traffic areas with EMF paint, a blocking material, or even EMF wallpaper, as well.
