Traspir Tightwrap - External Air Tightness Barrier Membrane
£599.95
Self-adhesive airtight vapour permeable membrane | Resistant to UV rays | Excellent weather and chemical resistance
The Traspir Tightwrap, or more technically known as "Traspir EVO UV Adhesive 250" membrane is the perfect choice for an airtight barrier that allows internal vapour to escape, and prevents new moisture from entering the construction.
It's self-adhesive coating means it can be applied quickly by general trade, adheres to almost any substrate, and can even be re-positioned if necessary.
The monolithic structure provides excellent weather and chemical resistance, and is robust enough to stand-up to the wear and tear of a construction site (see robustness testing on datasheet below).
The membrane consists of three active layers, an adhesive compound, and liner:
Top layer: highly UV ray-stabilised PP non-woven fabric
Middle layer: breathable monolithic PU film
Bottom layer: non-woven PP fabric
Glue acrylate dispersion without solvents
Release liner precut removable plastic film
Unlike alternative products, Traspir Tightwrap is resistant to UV rays. UV resistance is permanent even when exposed to open joints on façades up to 35 mm wide and uncovering a maximum of 30% of the surface area for façade application.
It has fire reaction B-s1,d0 and flame retardant capacity according to EN 13501-1.
The low flame spread and the impossibility of forming flammable particles guarantees the safety of the building and people
