Polyglass U.S.A. Inc. has announced that Polystick MU-X self-adhered, high temperature underlayment has been redesigned. A secondary water barrier for roof coverings, Polystick MU-X features an enhanced black polypropylene film, improving membrane walkability and reducing bleed through.
Polystick MU-X is designed especially for high temperature environments. It is rated as temperature resistant to 250°F and has an exposure window of 90 days for job flexibility. Polystick MU-X features a proprietary SBS modified bitumen upper compound and patented ADESO® dual-compound self-adhered technology on the bottom side of the reinforcement. A split release film on the bottom of the roll allows for ease of application. Convenient 3-inch lay lines printed on both edges allow bi-directional installation, saving time and labor.
