Durelis Vapour lock irtight moisture-resistant integrated vapour barrier board with Durelis Vapour ock is a Durelis board with an industrially applied, transparent vapour barrier on one side. Thanks to this technology, the Vapour ock vapour barrier has a constant μ value of over the whole surface of the board. ensures that the board is extremely airtight (< 0.001 m3/m2/h/Pa at 50Pa-1 mm). It is important to always seal all joints and cracks with suitable airtight tape. Durelis Vapour ock boards can be used in service class 2 (limited temperature and atmospheric humidity), in biological hazard classes 1 and 2 of EN Standard 335-3. Characteristics Product class P5 Structural Applications Moisture resistant Vapour retardant T&G Tongue-and-groove joints (optional) Applications - Roofs - Walls

Durelis Vapourblock Applications Durelis Vapourblock is an ideal solution for applications in timber-frame construction and in low-energy passive house building. Using Durelis Vapourblock on the inside of a building offers the advantage of combining an air barrier, vapour barrier and structural reinforcement, all combined in a single layer of board.
