Polystick TU PLUS is a self-adhered, dual reinforced waterproofing underlayment designed for use in adhesive foam or mechanically fastened roof tile applications. Utilizing ADESO® dual-compound self-adhered technology, Polystick TU PLUS features a UV resistant polymer modified bitumen plastomeric upper compound and a proprietary self-adhesive SBS (elastomeric) compound on the bottom. A split release film that protects the self adhesive compound allows for easy application.

TU PLUS features dual reinforcement consisting of an internal fiberglass mat and a superior polyester reinforced surface fabric. This reinforcement combination creates a robust membrane that provides puncture resistance to heavy tiles and deck and substrate imperfections. The top surface is engineered for both slip resistance and tile stacking.
Polystick TU PLUS features patented SEALLap® factory applied adhesive treatment at the membrane overlap which provides a quick watertight bond.

Although Polystick TU PLUS is designed as an underlayment for clay and concrete tile coverings, this membrane can also be installed under slate tiles. This product is suitable for the high temperature environments (up to 265°F) under tile, metal, and other roof coverings. Polystick TU PLUS can be installed as part of a multi-ply underlayment system when used over Polystick MTS PLUS.
