Paroizolacja?! A komu to potrzebne i gdzie ją dawać?

In this video, we demonstrate how to properly install the ISOVER Vario® XtraSafe intelligent vapor barrier membrane in an attic. We're working on a special mock-up at the ISOVER Training Center. ISOVER Vario® XtraSafe is an active vapor barrier with variable diffusion resistance (variable SD). In summer, it facilitates moisture removal from the structure and in winter, it prevents water vapor from penetrating the building envelope.
