MAMMOUTH® NEO Base is a thermoplastic polyurethane (TPU) self-adhered base ply for use in approved multi-ply membrane and flashing assemblies. MAMMOUTH NEO Base is composed of a proprietary formulation of bio-based TPU polymers in combination with a high tack self-adhesive layer and is reinforced with a high performance glass grid/glass fleece. The topside is surfaced with polyolefin burn-off film to optimize heat welding and the underside is surfaced with self-adhesive ribbon strips protected by a polyolefin release film that is removed during application.
Prior to installation, unroll MAMMOUTH NEO Base onto the roof surface and allow to relax. Place MAMMOUTH NEO Base in desired position. Remove the protective release film from the underside of the sheet and roll MAMMOUTH NEO Base into place with a weighted roller. Subsequent approved inter-ply or cap ply membranes are applied to MAMMOUTH NEO Base via heat welding.
