SOPREMA® and 3M Collaborate to Create Brighter Future

New, highly reflective granule-surfaced roof membrane developed.

SOPREMA SG granule-surfaced cap sheets are improved with 3M™ Highly Reflective Granules, delivering increased durability and a brighter, whiter appearance to the market. The new ultra-reflective granule is integrated into SOPREMA SG surfaced roof membranes, creating a solution that provides the SRI ratings needed to meet some of the highest U.S. requirements.

The SG granule far surpasses the industry standard SRI of 23 for standard “white” granules, as determined by Cool Roof Rating Council’s three-year aged SRI, coming in at an impressive rating of 75. It also meets some of the most stringent U.S. reflectivity requirements including Title 24, FBC and IECC. The cap sheets are lightweight and easy to handle, and the reflective granules can increase comfort for the occupants inside the building while reducing energy costs.  

“We are pleased to be the first to partner with 3M to provide this technology in low-slope roofing: a bright, reflective system without sacrificing multilayer bituminous waterproofing performance,” said SOPREMA Marketing Manager Matt Davis. “Our new SG products are not only durable and maintain their reflectance over the life of the products but are also lighter weight for easier handling and application for the installer.”

“SOPREMA has been a strong customer for some time, and we were pleased to work with them on this innovative endeavor. We’re proud to provide building owners with a reliable solution that is compliant with reflectivity regulations and helps reduce urban heat island effects,” said Amy McLaughlin, business director and general manager, 3M Industrial Mineral Products Division. “SOPREMA’s R&D team provided valuable insights on market and manufacturing needs and helped us conduct large-scale trials during the development of 3M Highly Reflective Granules. As a result of 3M working closely with the customer to create a solution that meets a specific market need, 3M’s new highly reflective granules exceed expectations during and after manufacturing and enable cap sheets to have high solar reflectivity levels years after installation.”
