The high performance of Firestone SBS Products has been well-established for many years, and Firestone UltraWhite™ granules, introduced in 2010, have demonstrated outstanding solar reflectivity, do not require coating or re-coating, and avoid the hail damage susceptibility associated with many other brands of reflective modified bitumen cap sheets.
Firestone is pleased to combine our SBS and UltraWhite products in the Firestone 30-Year SBS Platinum Warranty, now featuring additional options. Projects eligible for the 30-Year Platinum Warranty must meet the criteria shown below.
