SOPRAVAP® STICK ALU S 16 is a self-adhesive flexible SBS elastomeric bitumen water vapour control layer with a composite aluminium/non-woven polyester reinforcement. The self-adhesive underside is protected by a silicone release film and the topside is covered with fine sand.
-Auto-adhesive vapour barrier for steel cladding
Roll dimensions: 20 m x 1,08 m
Roll weight: about 35 kg
Storage: Upright on pallet with plastic wrapping, protected against moisture
SOPRAVAP® STICK ALU S 16 must be laid directly onto dusted steel deck or concrete.
• Brush and dry the support
• Unroll, place and adjust the roll
• Peel back a few centimeters of the silicone release film
• Proceed by laying this part onto the substrate
• Hold the membrane and pull off the silicone release film while carefully pressing down on it to avoid any bumps and air bubbles
• Recommended laying temperature + 10°C
• Longitudinal roll overlap is about 6 cm and transversal roll overlap is about 10 cm.
