Basic Interior Radio Frequency Shielding Protection

Our Aluminum RF Shielding Foil is designed to block analogue and pulsed digital signals from exterior sources such as microwave transmitters, cell phone towers, neighbours / neighbours' cordless telephones, Wi-Fi signals, smart meters and more.

This foil also offers an effective barrier against low frequency AC electric fields when grounded.

RF Shielding Foil was designed for new construction and renovation.

It has excellent RF shielding qualities and is a very versatile product that can be applied under drywall as a vapor barrier, under shingles on roof tops, in the attic, under stucco and plaster.
