The recently improved underlayment offers an uncovered exposure time, without any degradation, of six months — twice the time of its original three-month uncovered exposure time.

Polyglass is introducing Polystick P, a self-adhered waterproofing underlayment designed to resist temperatures up to 250 degrees Fahrenheit.

The Gulfeagle SecureGrip25 is 48 feet wide and 250 feet long, provided in “Gulfeagle blue” and boasts a 90-day exposure rating and a 25 year material warranty.

Polystick XFR utilizes two technologies: patented ADESO® self-adhered technology and patent pending Burn-Shield Technology™, which can achieve the highest level of fire ratings.

Visit booths #3215 and #3512 at this year's International Roofing Expo to see Polyglass' modified bitumen membranes, roof underlayments and roof coatings.

This self-adhering “self-stick” roofing underlayment is composed of a high-grade, reinforced polyester fabric laminated to a high temperature asphalt adhesive system.

PrimeSource Building Products recently was awarded a patent for its innovative design of a synthetic underlayment called ShingleLayment, which the company claims is the only synthetic underlayment in the market designed to protect a roof and look like a shingled rooftop during construction.
