YCF-80-100 is one-side metallised wallpaper for the shielding of high-frequency radiation (HF) and low-frequency electric fields (EF). The basis for this products is a white wallpaper base, certified to FSC© Mix Credit, from the worldwide biggest manufacturer. This wallpaper has a very high dimension stability before, while and after processing.
Important: As this also addresses EF, it is recommended that it is grounded using the grounding cable, here or using a grounding plate which is installed by an electrician. Contact me if you prefer this option.
A new coating process allows to completely apply the metal on the base material with the use of air and green electricity only, without chemicals. The ecological awareness for this is very high. High vapour permeability: Instead of an area-wide application the metal alloy is applied spattered on the base material. This is why the YCF-80-100 products are highly vapour diffusive.
To be used on interior walls and ceilings. Applicable for loose laying, if the wallpaper is protected against mechanical damage. Not for external use.

Loose laying / stapling
Always overlap the single sheets by at least 5 cm. There should be no gaps / holes.
Applying the metallised surface to the wall
The issue is, that for a proper grounding, the sheets must be electrically connected with each other – achieved by using the conductive tape, which is connecting the single sheets with each other. It is best to apply the conductive tape to the wall first and then adhere the sheets with standard wallpaper paste onto the wall.
Applying the non-metallised surface to the wall ** RECOMMENDED **
This is the best option, even though aesthetic result is not as pleasing. But in return, all sheets subsequent can easily be connected and grounded.
Ideally the sheets should be glued on overlapping to achieve the best attenuation. As a next step the overlapping sections should be smoothed with a fine filler. However, you won’t achieve a perfect even surface.
Alternatively, you can glue on the sheets edge to edge as normal for wallpapers and run a length of conductive tape across the join. Some attenuation may be lost.
