California Title 31 Compliant
CoolStar® Ultra technology boosts solar reflectivity while protecting the membrane from UV damage. This is especially valuable in Los Angeles County, where Title 31 mandates cool roofs for new construction to help reduce heat‑island effects.
Choose from a growing portfolio of torch-down and self-adhered solutions to deliver a cooler, more durable roof that meets essential environmental and energy‑efficiency standards.
A Scientific Solution
CoolStar® Ultra surfacing uses naturally occurring aggregate processed into bright‑white, UV‑opaque granules. These granules protect the asphaltic membrane from UV degradation, maintain strong granule adhesion, and deliver superior solar reflectance.
