524G RCap™ Plus Reflective Cap Sheet

Features & Benefits

A fire-rated cap sheet manufactured with reflective granules for conventional or modified built-up roofing systems. Can be applied with hot mopping asphalt or cold process adhesives as the surface membrane in multi-ply roofing systems.

Please contact Malarkey's Technical Services Department for approval of roof systems.

524G RCap™ Plus is manufactured on a non-woven fiberglass mat, impregnated and coated on both sides with SBS polymer modified bitumen (asphalt), and compounded with a fire-retardant mineral stabilizer. 524G RCap™ Plus is surfaced with reflective granules for ultraviolet protection, weatherability, and solar reflectance.

524G RCap™ Plus is listed in the CRRC directory, meeting the requirements of the California Title 24, Part 6 and allowing for overall energy savings due to the solar reflectance of the cap sheet.

524G RCap™ Plus Benefits:

• Reducing energy use: A cool roof transfers less heat to the entire building, allowing the structure to stay cool and use less energy for air conditioning.

• Reducing air pollution and greenhouse gas emissions: Lowering energy use with cool roofs can decrease the production of associated air pollution and greenhouse gas emissions.

• Improved comfort: Cool roofs can reduce the overall air temperature inside buildings with or without air conditioning.

 

Cool Roof Rating Council ratings are determined for a fixed set of conditions and may not be appropriate for determining seasonal energy performance. The actual effect of solar reflectance and thermal emittance on building performance may vary.
Manufacturer of product stipulates that these ratings were determined in accordance with the applicable Cool Roof Rating Council procedures.
