LAMA2ply
LAMA 2PLY is a premium roofing system that combines the strength and durability of SBS-modified bitumen roofing membranes with the added reinforcement of polyester. This two-ply system is designed to provide superior protection against water and other elements, ensuring that your roof stays watertight and secure.
The LAMABase sheets feature burn-off films on both the top and bottom surfaces, while the LAMACap sheets have a mineral granule coating on the top surface and a burn-off film on the bottom. Both sheets have a 3.5″ overlap, which ensures a water-tight bond when applying the system.

Application Field
LAMABase
• Heat-welded.
• Mechanically fastened.
• Applied on hot bitumen.
LAMACap
• Heat-welded on LAMABase.
Application Method
- Lay down the rolls so that the lower face with polyethylene film is bonded to the substrate.
- To fix the sheet to the substrate, use a propane gas burner to melt off the polyethylene film and a thin layer of bitumen while unrolling and laying the membrane. Side laps 100 mm and end laps 150 mm.
- The membrane may be loosely laid, partially, or fully bonded, depending on the structure and the specifications.
