Product description

Drylast CRWR® High-Albedo Cool Roof Coating is a cutting-edge solution designed to address the pressing need for energy-efficient and sustainable building practices. This single-layer, high-solid content polysiloxane coating is specifically formulated to retrofit existing rooftops made of bitumen, EPDM, PVC, or metal, transforming them into highly reflective surfaces that significantly reduce energy consumption and CO₂ emissions.

By reflecting up to 88% of sunlight, the coating achieves an impressive Solar Reflectance Index (SRI) of 111, effectively lowering peak roof surface temperatures by half and indoor climate by up to 10 °C. This results in substantial HVAC energy savings of up to 30%, contributing to a greener and more cost-effective operation of buildings.

Not only does Drylast CRWR® offer exceptional performance in terms of energy efficiency, but it also boasts elastomeric durability with 500% elongation, hydrolysis resistance, UV stability, and is free from PFAS chemicals. The ease of application via rolling or spraying makes it a versatile and practical solution for a wide range of building types, including industrial, retail, logistics, and public buildings.

Moreover, the coating's ability to extend the lifespan of roofs by eliminating thermal stress and microcracking further enhances its value proposition. By supporting urban cooling initiatives and aligning with circular economy principles through the upcycling of existing roofing materials, Drylast CRWR® stands out as a sustainable and environmentally conscious choice for building owners and operators.
