RDF25 shielding window film | HF screening attentuation against electrosmog up to 35 dB | 25 % light transmission | Effective against 5G!

Technical data for shielding window film RDF25

• Screening attenuation: up to 35 dB. Unless otherwise stated, the indicated dB-values apply to 1 GHz. Measurement from 600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006.
• Width: 76 cm / 152 cm
• Length: by the meter / 30 m roll
  
• Light transmission (transparency): 25%
• Edge sealing necessary: yes, with FL4 edge sealant
  
• Color of light (daylight coloration): brown
• Indoor use, mainly on glass but also on doors and other flat surfaces.
• Mounting: Water-activated and pressure-sensitive adhesive on the back.
• Material thickness: 50 µm
• GroundingGrounding is an electrically conductive connection with the electric potential of the ground. More: Not electrically conductive. No protection from electric alternating fields (LF).
• Application: Windows
• Field type: HF (high-frequency electromagnetic fields)
• Ecology: Normal
• Indoor application only on non heat absorbing glass surfaces! Background: Heat-absorbing glass is already metallized. 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. Check the type of glass in advance!
• Outdoor application even on heat absorbing glass surfaces. This window film is specially designed for outdoor application. The solar radiation is blocked, this is why the window cant heat up. This film is especially approved for thermal insulation glazing.

Processing of the HF electrosmog shielding windows 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.

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 FVR10. After a few weeks, the edges of the window film must be sealed with FL4 edge sealant.
