Barrier Alu 150 - All Sizes

BARRIER ALU 150 28B is laid parallel to the eave line, starting from the lower edge of the roof. The second layer should overlap the first by at least 10– 20 centimetres (depending on the slope of the roof), as shown in the layout in compliance with UNI 11470:2013. The sheet should be applied to a continuous support with a mechanical fastening.

The cavity closer acts as a seal, preventing external water vapour and damp from entering the cavity wall and the building

Once the top of the roof is reached the membrane should extend beyond the ridge by at least 30 centimetres to facilitate a perfect overlap with the ends of the sheets overlapping on the other pitch of the roof. The sheets should also be overlapped by 30 cm at the head joints. The possible presence of an integrated double adhesive band may substitute correct sealing from air and water.
