BWK Solid SD 107 PE Classic three-layer vapor barrier

Description

Three-layer polyethylene membrane used as a vapor barrier and airtightness membrane. Its three-layer construction provides appreciated handling flexibility over large widths, with the product delivered in 4-meter-wide sheets. It creates the interior airtight envelope, protects insulation from unwanted air movement, limits vapor diffusion within the wall assembly and thus prevents internal condensation and the formation of dew points. It also prevents moisture trapping for frames and roof structures that may contain significant residual moisture. Its field of use covers rooms with low, medium and high humidity levels. It complies with DTU 31.2, which sets a permeance less than or equal to 0.005 g/m².h.mmHg corresponding to an Sd value of 18 m, as well as with the NF EN 13984 standard. 100 m² rolls.
