Underlayment Features Improved Membrane Walkability

Polyglass U.S.A. Inc. has redesigned its Polystick MU-X self-adhered, a high temperature underlayment. A secondary water barrier for roof coverings, Polystick MU-X features an enhanced black polypropylene film, improving membrane walkability and reducing bleed-through.

This high temperature underlayment features an enhanced black polypropylene film to improve membrane walkability and reduce bleed-through.

Polystick MU-X is designed 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. Three-inch lay lines printed on both edges allow bi-directional installation, saving time and labor.
