how to block radio waves in your house

Radio waves are electromagnetic radiation that constantly bombards your home from every direction, all day, every day. These waves are harmless and pose no risk to your health, but they can be annoying if you want complete privacy in your home.

Therefore, the question of how to block radio waves in your house has arisen. Fortunately, there are simple ways to stop radio waves and keep them out so you can have complete privacy and silence as you please. Let’s dive in to find out now!

How to Block Radio Waves in Your House (Detailed Instructions)


There are five ways to block radio waves in your house, including shielding paint, protective sleeping canopies, RF-blocking wallpapers and films, and radiation shields for your appliances.

1. Use shielding paint

A carbon-based RF blocking paint is the most suggested product to use when radio waves are extremely powerful that other substances can’t obstruct them. It creates a protective layer that may be applied to both external and inner walls to prevent radio waves from penetrating effectively.

There are paints on the market that can block up to 99 percent of RF and microwave radiation. These paints are intended to be used as a primer in the interior and can also be painted over with regular latex paint.

2. Use protective sleeping canopies

EMF and RF exposure disrupts brain wave patterns, affecting sleep quality. Protective canopies can decrease exposure by blocking 95-99 percent of EMF/RF with their polyester-copper-silver mesh.

The sheet has a hem on every side and is intended to be used under the bed or carpet. It’s critical to place this item and the canopy in a low AC electric field area to get the best results.

The canopies are generally composed of silver or aluminum, which is similar to the RF-blocking net fabric. As a result, they don’t feel cramped and enable enough fresh air to flow into your sleeping space.

3. Use a window EMF/RF shielding film

Shielded window film may be required if the region surrounding your home is densely packed with cellular towers, antennas, or other RF emitters.

The majority of EMF and RF radiation that enters a home comes in through the windows. These shielding coatings can suppress 5 GHz frequencies by up to 99 percent (most cell phone signals work at 2.4 GHz). Simply cut the size you need from the roll and put it on the window to utilize the film.

4. Use a wallpaper that blocks radio frequencies

Internal wall proofing using wallpaper that blocks RF is a fantastic choice. When it comes to installation, keep in mind that the flat side should be attached to the wall. The opposite side, which will be painted over (with paint), is the thing that will be exposed.

5. Use electric filters

High-frequency radiation, or “dirty energy” produced by standard household equipment can be reduced by electric filters.

The number of filters required is determined by the number of appliances used in the establishment, not by the size of the house or building. Around 20 filters would be needed for an average-sized home.

What Materials Block Radio Waves Most Effectively?


Removing all radio waves from your house might be challenging, depending on where you reside. However, the good news is that you can build your own home and use materials that block radio waves.

Here are several materials that can be used to get rid of radio waves:

1. Radio Waves Reflection with Dielectrics

Even though dielectrics block radio signals flowing through, they absorb and reflect a significant amount of their energy. When a moving radio wave collides with a dielectric substance, the material retains some of the waves’ power, transforms it, and distributes it using thermal energy.

According to Adrian Popa, director emeritus of Hughes Research Laboratories, a silvery mirror reflects around 95 percent of radio radiation while absorbing about 5%.

Other dielectric compounds include the following: Ceramic, Wood, Plastic, Paper, Teflon. Pure liquid water, in addition to these solid components, is an exceptional dielectric.

But be cautious! Dielectrics must be relatively thick to significantly influence RF absorption. As a result, a thin layer of water or a single sheet of paper will not shield anyone from radio wave signals.

2. Radio Waves Reflection with Conductors

Conductors are entirely metal, unlike dielectrics which are mainly non-metallic. The following are some examples of outstanding conductors: Gold, Aluminum, Copper.

By diverting that radiation and keeping it out of your house, they can work miracles.

Depending on the content and thickness of the materials in your home, you may be able to block radio frequency signals and 5G signals successfully. You may substantially minimize your total exposure to EMF radiation by surrounding your interiors with the proper chemicals in suitable quantities.

Frequently Asked Questions About Radio Waves

1. What materials do radio waves go through?

Non Conducting materials like wood, bricks, and concrete may be penetrated pretty easily by radio waves. They are unable to travel through electrical conductors like water or metals. Radio waves from distant space can reach Earth’s atmosphere above v = 40 MHz.

2. What reflects radio waves?

Radio waves are unlikely to be interfered with by plastic wrap, wax paper, cotton, and rubber in small amounts. Aluminum foil and other electrically conductive metals like copper may reflect and absorb radio waves, interfering with their transmission.

3. Are radio waves harmful?

Non-ionizing radiation is not a carcinogen, according to a scientific agreement, and it has not been demonstrated to cause any harm to individuals at or below the FCC’s radio frequency exposure guidelines. While in operation, cell phones produce modest amounts of non-ionizing radiation.

4. Does gold block radio waves?

Yes, gold can interfere with radio waves and reflect them.

5. Does fiberglass block RF signals?

If the fiberglass insulation in the walls and attic is thick enough, it can somewhat impede mobile phone signals while being porous. Foil facing on insulation goods such as foam board or fiberglass batts can inhibit radio frequency signals.
