Self-Adhered Membranes Could Expand Roofing Season

Polyglass U.S.A., Inc., a leading manufacturer of roofing and waterproofing systems, has expanded its self-adhered product offering with the addition of Elastoflex SA V Polar Base and Elastoflex SA P Polar Cap.

Optimized for performance in colder conditions, these resilient roofing membranes save on labor and can extend the roofing season. The membranes allow for roof system installation in temperatures between 25 °F and 60 °F (4°C and 16 °C).

Long-Term Performance

Designed for long-term performance, the Elastoflex SA V Polar Base is fiberglass-reinforced for excellent dimensional stability, while the Elastoflex SA P Polar Cap has a UV-stabilized granule surface and is polyester-reinforced for puncture and tear resistance.

Manufactured with the ADESO dual-compound, self-adhered technology, these premium membranes provide a cleaner installation, improve application speed, and eliminate the need for torches, according to the manufacturer.

Both base and cap sheets use a elastomeric styrene-butadiene-styrene (SBS) formulation on the top weathering side of the reinforcement and an aggressive self-adhesive formulation on the bottom side.

Unique Product Qualities

According to the manufacturer, the products have unique qualities that improve efficiency and performance. The Elastoflex SA V Polar Base is finished with laylines for ease of application, while Elastoflex SA P Polar Cap features patent pending SEALLap Ultra and patented FASTLap for immediate and more effective bonding of side and end-lap seams.

“We are excited to introduce roofing solutions that may extend the roofing season,” said Polyglass CEO Natalino Zanchetta. “We continue to focus on innovation and providing products that make roofing in challenging weather conditions possible.”
