MAMMOUTH® NEO Cap is a thermoplastic polyurethane (TPU) cap ply for use in approved multi-ply membrane and flashing assemblies. MAMMOUTH NEO Cap is composed of a proprietary formulation of bio-based TPU polymers reinforced with a tough, dimensionally stable non-woven composite polyester mat. The topside is surfaced with black mineral aggregate and underside is surfaced with polyolefin burn-off film to optimize heat welding.
Prior to installation, unroll MAMMOUTH NEO Cap onto the roof surface and allow to relax. Position MAMMOUTH NEO Cap in desired position and back roll the product. MAMMOUTH NEO Cap is then heat welded to approved substrates.
