Architects and other commercial roof specifiers can protect and accent flat and low-slope roofs with the Kemperol cold liquid-applied membrane roofing and waterproofing system from Kemper System America Inc.
Kemperol 2K-FR is derived from the Kemperol Reflect2K-FR resin system. Kemperol 2K-FR is fully reinforced and features thru color. It does not need a color topcoat because the resin is tinted throughout.
Designed for extended life on new or existing low-slope roofs, the Class A fire-rated, odor-free polyurethane resin (PUR) system is now available in Stone Gray or Patina Green.
White Roofs Not Always Best Choice
While white roofs are generally preferred in warmer regions where they can help lower building cooling requirements, the overall energy-saving benefit diminishes and becomes undefined further north, he said. In addition, high reflectivity may not be desirable for certain projects or areas. For example, some roof areas may be in shadow most of the day, and in sunny areas of the roof, glare can be intense on floors immediately above. Reflected glare can also contribute to excess heat build-up, which can make occupants uncomfortable and add to air conditioning costs. Reducing glare can also be important for hospitals, schools and offices.
For roof projects that can benefit from a high Solar Reflectance Index (SRI) roofing, Kemper System offers two cool-roof membrane systems – Kemperol Reflect2K-FR (SRI 110), a PUR, and Kemperol AC Speed (SRI 108), a PMMA. Kemper System also offers two elastomeric-based products which can be brush-, roller- or spray-applied – Roof Guardian® RG-180, a fibered white acrylic elastomeric roof (SRI 108), and Roof Guardian RG-170, a white elastomeric coating (SRI 109).
