EMF Protection for Home

Electromagnetic frequencies (EMF) surround us daily, whether from WiFi, cell phone signals or the electromagnetic fields produced by everyday devices. Protection from EMF is critical to ensure that your electronics function properly, as labile electromagnetic waves cycling at the same frequencies can disrupt circuitry, causing electronics to malfunction.

EMF Shield

The most practical solution to protect devices is to surround them with electrically conductive material creating a Faraday cage around your device. A Faraday cage distributes electrical charge around the surface, preventing incoming waves from interfering with the electric fields interior to the enclosure.

EMI Shielding Materials

Electrically conductive materials such as foils, tapes and meshes are used to surround circuitry for protection. While effective, the application of these materials is line-of-sight, meaning they are less conformal and more prone to having slight gaps which allow leakage of electromagnetic interference (EMI). Further, these materials are unsuitable for shielding large areas as expense and coverage make this impractical. Here, electric paint provides a much better solution as it’s easily applied over large surface areas giving complete coverage and a cured film that’s highly durable and cost-effective.

How to Shield your Home from EMF

People concerned about EMI can shield their homes by applying conductive paint on the interior walls of their homes. These coatings can be applied directly onto the drywall without primer and painted over with water-based paint for desired esthetic. Paint can be applied throughout the entire house or confined to individual rooms. It is important to note that wireless devices such as cell phones or laptops connected by Wifi will not work in these areas restricting electronic usage to devices that are hardwired only.
