Permeable airtight membrane with two self-adhesive strips
PAVATEX LDB 0.02 is used as a second fit airtightness layer when re-covering the roof while retaining and/or extending the existing between-rafter insulation with PAVAFLEX. A top cover with ISOLAIR (minimum thickness 35 mm) must then be applied. The airtight seal is formed with the PAVATEX LDB 0.02 laid flat, directly on the upper side of the rafters. The longitudinal joints are glued using the integrated two-way self-adhesive strips. Airtight glueing of the transverse joints, the connections and penetrations are done using PAVATEX sealing products.
- If mechanically secured, PAVATEX LDB 0.02 can be left exposed to the weather for 1 week.
See the detailed PAVATEX installation instructions for the application of PAVATEX LDB 0.02 in walls.
