The RDF72 shielding window film contains 12 metal layers and thus provides a shielding effectiveness of up to 30 dB, even up to 40 GHz. Nevertheless, we recommend using shielding curtains. Effective against 5G!

This self-adhesive RDF72 special film contains 12 precious metal coats and is suited for protecting from high-frequency electromagnetic radiation caused by mobile radiation from transmitters, mobile phones, smartphones, WLAN, etc. It is typically stuck on the inside of windows without glazing.

Despite the screening attenuation of up to 30 dB, we only recommend using it sparingly because when using the shielding window film, the window frame remains unprotected because the attenuation is weak. Generally, shielding curtains should always be preferred. However, there are uses that make shielding window films useful, such as on windows and doors inside buildings.

The RDF72 shielding film’s light transmission is 72 %. RDF72 is our premium shielding film with 12 metal layers for the highest standards of quality. The screening attenuation achieved is unparalleled for a film with such high light transmission!

Made in USA

Only use indoors on glass surfaces WITHOUT GLAZING!
Thermal glazing is already metalized. If solar radiation permeates the metallization and then hits the shielding window film, multi-reflection may occur. The window frame heats up needlessly and can thus cause leaks or even cracks by expansion of the frame! Always find out the glass type!

Processing of the HF electrosmog shielding window film

The bubble-free application of the shielding film is not simple and it is recommended to do with another person. First, remove all unevenness and dirt on the glass with a cleansing extract and glass plane. Then, thoroughly clean the glass with window cleaner.

FL4 edge sealant pen for RDF72 PREMIUM shielding window film. 10 mL. Absolutely necessary!Remove the protective film from the shielding film. Distill FMK30 mounting concentrate with 0.5 liter of water! Dilute the water and spray the window surface as well as the adhesive side of the shielding film. Put the window film on the window pane and work from the middle to the outside and remove the air bubbles with the scraper. After a few weeks, the edges of the window film must be sealed with FL4 edge sealant. Detailed instructions come with the film.

Quantity and cancelling the order

If cut in measures of 1.0 running meter according to the customer’s specifications, it is not possible to return or cancel the order. For this reason, it is possible to request a free sample of the shielding film. By ordering pre-finished products, waiving the statutory right to return goods is accepted.
