This product is not sold individually. You must select at least 4 quantity for this product.

EMF shielding fleece with attenuation 60 dB @ 1 GHz. For interior and exterior most universal usage. High ecology.

Width: 100 cm

Length: 1 linear meter

YTS-60-100 is a one-side metalized, most universal usable fleece made from Tyvek® softstructure for the shielding of high frequency radiation (HF) and low frequency electric fields (LF). Tyvek® is combining the best properties of paper, fleece, films and fabric. It is waterproof, windproof, permanent moistureproof and is still providing a high vapour permeability. Tyvek® is extremely tearproof.

Application: Wall interior, Ceiling, Floor

Field type: LF (low frequency), HF (high frequency)

Ecology: Very high

Color: Silver, Beige

Earthing: Electrically conductive. Can be contacted and grounded to shield electric fields (LF). Please find corresponding components under "Grounding".

Special feature

Very high ecology: Almost all EMC shielding products become metalized in a “chemical” procedure. A lot of chemicals are needed for the production of copper- and nickel-layers. Our 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 all Y-serial products are highly vapour diffusive.


For interior and exterior most universal usage. As base wallpaper, sub-membrane, under-tile vapour barrier for roofs, facing sheet for ventilated wood facades, drywall installation, loose laying, etc.

Loose laying / stapling: Always overlap the single elements for at least 5 cm. Do consider that there should be no gaps / holes.

Bonding the metalized surface in direction wall: The issue is, that for a proper grounding, the sheets must be electrically connected with each other. Usually this is attained by using the grounding strap EB1, which is connecting the single sheets with each other. When bounding the sheets with the metalized surface in direction wall this is not possible. If you still decide to do though, you will have to apply the grounding strap EB1 to the wall first and then adhere the sheets with standard wallpaper paste onto the wall. This will give a slightly chance that the metalized side will be contacted with EB1. Because this depends on the glue, we recommend to carry out experiments.

Bonding the metalized surface in direction room: This is the best solution, even though the result is not so nice. But in return, all sheets subsequent can easily be connected with EB1 and grounded then.

Edge to edge or overlapping: Ideally the sheets should be glued on overlapping to achieve the best attenuation. As a next step the overlapping 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. This will cause a low loss of attenuation.
