ST:73 Oventilerat plåttak med lösull [REI30] [46 dB]

An efficient, space saving, fire and moisture safe roof construction, suitable for single and multi-family houses with focus on sustainable building and passive houses with normal moisture loads indoors. The roof is designed with wooden beams without an air gap, with ISOVER Vario Xtra on the inside and VEMPRO™ R+ Underlagstak on the outside. ISOVER Vario Xtra, a smart variable vapor retarder, has a water vapor resistance that adapts to the relative humidity. The product opens when the relative humidity gets high, which means that it is not recommended to be used in areas with constant high relative humidity indoors. A prudent assessment has been made in connection with acoustic simulations, which means that the roof's sound reduction may differ from the reported values.
