{"product_id":"membrane-traspir-evo-uv-115","title":"Traspir EVO UV 115 · UV-resistant monolithic breathable membrane","description":"\u003cp\u003eOpen-joint cladding and rainscreens leave the membrane on show. Daylight, wind-driven rain and heat all reach it through the gaps, and a standard wall membrane will not survive there. TRASPIR EVO UV 115 is built for that build-up: a highly UV-stable non-woven polypropylene top layer over a monolithic PU coated breathable film.\u003c\/p\u003e\n\u003cp\u003eIt keeps water and wind out of the structure while letting the wall dry outwards, and it holds its performance on facades that swing between hot and cold, including metal cladding. Behind open joints it is rated as permanently UV stable, so the gaps in the cladding are not a problem for the layer behind them.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePermanent UV stability behind open joints up to 30 mm wide, with no more than 20% of the surface left uncovered.\u003c\/li\u003e\n\u003cli\u003eMonolithic PU coated film: watertight and windtight, and still breathable.\u003c\/li\u003e\n\u003cli\u003eSuitable for metal facades with high temperature fluctuations, with a service range of -40 to 120 degrees C.\u003c\/li\u003e\n\u003cli\u003eReaction to fire Euroclass B-s1,d0 to EN 13501-1.\u003c\/li\u003e\n\u003cli\u003eLight to handle at 115 g\/m2 and 0.3 mm thick.\u003c\/li\u003e\n\u003cli\u003eConforms to EN 13859-2, the harmonised standard for flexible wall underlays.\u003c\/li\u003e\n\u003cli\u003eOne code, TUV115.
