Malarkey Roofing Products has introduced the RCap Plus cap sheet for low slope, commercial roofing systems. It features reflective white granules embedded into the membrane to reflect ultraviolet rays and absorb less heat.

RCap Plus utilizes ground and packed granules, and these granules ensure more coverage in the membrane per square. Malarkey grinds the asphalt granules at its South Gate, Calif., manufacturing facility.

The solar reflectivity and limited heat absorption of the RCap Plus cap sheet are key design features of the product. RCap Plus meets CEC Title 24, Part 6 standards and has an initial Solar Reflectance Index (SRI) rating of 87. As part of a roof system, RCap Plus may help decrease energy costs used to cool the building and extend roof service life.
