RF558 | Window film | Width 76 cm | 1 meter

Window film with 62 % light transmission in bright gray. Attenuation 18 dB. Indoor application on non heat absorbing glass surfaces.

Properties

Precious metal coated and self-adhesive special window film for shielding of high-frequency radiation (HF). Window film with 62 % light transmission in bright gray. Attenuation 18 dB. Indoor application on non heat absorbing glass surfaces.

Application

For the application you mandatory need our  plastic scraper FVR10 and the mounting concentrate FMK30, see our accessories below. An assembly instruction is included in the delivery.

Technical data

• Width: 76 cm.

• Length: Linear meter / 30 m roll

• Attenuation 18 dB at 1 GHz

• Light transmission: 62 %

• Color of daylight: Bright gray.

• Mounting: Water-activated, pressure-sensitive adhesive to the back.

• Material thickness: 37.5 µm.

• Only for indoor application 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!

Grounding

This product with an electrically isolated surface cannot be contacted or grounded.

Shielding attenuation HF & LF

This product shields high frequency electromagnetic fields (HF). 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.

Laboratory & expert report of shielding attenuation up to 40 GHz

We have already invested in our own professional EMV laboratory years ago. We not only use it to create our laboratory screening reports but also to check each batch daily. Additionally, we have all our products checked by an independent, well-respected expert. Double checked for twice the safety
