Polyglass Polystick MTS PLUS Premium Self-Adhered High Temp Roof Underlayment 39 in x 65.67 ft, 215 sq ft

Polyglass Polystick MTS PLUS Premium Self-Adhered High Temp Roof Underlayment is a professional-grade self-adhered underlayment engineered to provide superior protection beneath shingles, shakes, tile, or metal roofing. Each 39 in × 65.67 ft roll covers 215 sq ft and is designed with a high-strength, fiberglass-reinforced surface that resists tears during installation. This synthetic construction is designed to lay flat and provides a slip-resistant walking surface to enhance safety and ease of use during installation.

Because the underlayment is made from durable rubberized asphalt materials, it does not absorb water or wrinkle like traditional felt. The material resists mold growth, ensuring a dry and stable roof deck. Polystick MTS PLUS is up to 12 times stronger than traditional #15 felt, offering excellent wind resistance and durability even during heavy roof traffic and harsh weather conditions.

Polystick MTS PLUS is lightweight, with a nominal weight of 74 lbs per roll, and can be easily handled by roofing crews. Its advanced backside non-slip coating and 180 days of UV exposure resistance allow for faster, wrinkle-free installation and longer-lasting protection for the roof deck until the primary roofing material is applied.
