Self-adhesive bitumen membrane for vapour barriers
The waterproofing bituminous membrane IZOSELF AL PLUS is used as vapour barrier in flat roofs systems, in particular on a supporting trapezoidal metal sheet. It can also be used for waterproofing of basements, especially as protection against radon. The membrane is installed in such a way that during unrolling the easy removable siliconized film is removed while pressing it at the same time to the surface. To achieve immediate adhesion hot air or a flame is used at installation of the membranes to increase adhesiveness. The membrane is laminated on top with thin Al foil, on the bottom side protected with easily removable siliconized film. The product is in conformity with SIST 13970 and SIST EN 13969 for type A and SIST 1031.
