Premium Bright White solution

Manufactured using our patented CURE Technology®, our Polyfresko G® modified bitumen membranes not only meet and exceed most cool roofing standards but are also designed to resist granular loss, asphaltic bleed, and color staining. This means your membrane roof will retain its reflectivity and color integrity for many years to come.

Multi-Ply Polyfresko System Advantages:

• Premium membrane construction for superior durability and puncture resistance
• Featuring patented CURE Technology®
• Demonstrated to maintain exceptional reflectivity over time: Solar Reflectance Index (SRI) Initial: 96, 3-Year Weathered: 82
• Energy efficient, eligible for LEED® points as part of a qualified cool roof system
• Exceptional granule retention; 0.09g (APP) or 0.11g (SBS) loss vs. ASTM maximum 2.0g
• Minimal “torch scorch” for improved aesthetics, stain-free, and will not discolor over time
• Polyglass Detail & Repair Finish accessory specifically designed for application to membrane lap areas, details, and repair; displays the same reflective properties and appearance of Polyfresko membrane

Bright White membranes feature an initial SRI of 85 and a 3-yr aged value of *CRRC Rapid Ratings: Interim laboratory-aged values, meeting ordinances such as Miami 21, LEED, Title 24, Denver GBO, and Chicago Building Code.
