RDF72-Premium is a transparent film consisting of 12 metal layers for highest demands with an unrivaled attentuation and a very high degree of light transmission.

The RDF72-Premium is the best choise for windows and glass surface shielding from high frequency radiation. The particular product is used only for indoor application on non heat absorbing glass surfaces! Heat-absorbing glass is already metallized so when solar radiation permeates the metallization and subsequently hits the window foil, multi-reflections may occur. The windowpane will needlessly heat up and thus by expansion cause leaks or even cracks in the border-seals. It is highly recomented that a check in the type of glass in performed in advance!




The shielding attenuation is regularly tested in our own laboratory or by Prof. Dipl.-Ing. P. Pauli of the University of the German Federal Armed Forces in Munich, Germany according MIL-STD 285 and IEEE-Standard 299-1997.

Mounting Accessories

The mounting requires a bit of craftsmanship skills and adequate accessories:

  1. Mounting concentrate FMK30 for wet bonding, 30 ml for 0.5 liter of water.
  2. Plastic scraper FVR10 for a bubble-free bonding. With the felt-edge the water and the bubbles can be pressed out, without sctratching the film-surface.
  3. Aerosol can FSF, 0.5 liter.
