Active Vapor Barrier
Functions as a vapor control layer beneath the thermal insulation.
In the structure of a ventilated pitched roof, by placing LDS 5 on the internal (warm) side of the thermal insulation in combination with a vapor-permeable and waterproof membrane on the external side, the retention and condensation of moist and warm air from the interior of the room are prevented, ensuring comfortable living conditions in the under-roof space.
