Durable roofing underlayment effectively tackles extreme heat and weather

By Jesse Sanchez. 

Innovative, self-adhering underlayment provides reliable, lasting protection for metal and tile roofing systems. 

BITEC Inc., an established leader in roofing solutions, brings a premium offering with its MAT-40 self-adhering metal and tile roof underlayment, designed to meet the demands of both extreme temperatures and rigorous installation conditions. Crafted for professionals and durable roofing needs, MAT-40 is engineered to withstand temperatures up to 260°F and address the harshest roofing environments without compromising quality. 

The MAT-40’s unique composition includes a polyester and fiberglass scrim, known for its high strength and dimensional stability. This blend is complemented by a specially formulated SBR polymer-modified adhesive, enhancing its bonding power while ensuring slip resistance. According to BITEC, “MAT-40’s unique composition allows it to be applied in conditions where roof temperatures reach 260°F,” a notable feature given that standard underlayment materials often struggle in high-heat environments. 

Beyond its composition, MAT-40’s benefits extend to installation efficiency. The underlayment features an easy-to-remove peel-off release film, simplifying application while reducing labor costs. Its monolithic coating and saturating process further boost its waterproofing capabilities, ensuring that the MAT-40 resists both punctures and tears, even in challenging conditions. Notably, the product can endure up to 120 days of exposure to the elements without compromising its integrity, offering builders flexibility in scheduling without fear of material degradation. 

Headquartered in Morrilton, Arkansas, BITEC continues to innovate since its 1986 inception, with MAT-40 embodying the company’s dedication to high-quality materials and service. For those interested in a robust, easy-to-install roofing solution, MAT-40 could be the reliable underlayment option they need — combining resilience, convenience and the trustworthy support of an industry-leading manufacturer.
