The Kooltherm® K100 Series is a premium rigid insulation product line engineered to deliver exceptional thermal performance within a thin profile. Featuring a fiber-free rigid thermoset phenolic core, the series provides R-values of up to 8.3 per inch, enabling architects and project teams to achieve demanding thermal performance requirements with less insulation thickness.
The K100 Series includes application-specific solutions for cavity walls, rainscreen systems, wood and steel framing, concrete sandwich wall systems, soffits and interior wall applications. Its high R-value can enable slimmer building envelope assemblies, preserve valuable interior space and provide greater flexibility when detailing space-constrained conditions.
Beyond thermal performance, Kooltherm® K100 combines strong fire and moisture performance with a lightweight, fiber-free construction. The series offers ASTM E84 Class A performance across multiple applications, while its closed-cell phenolic core helps resist moisture and water vapor ingress. Together, these attributes provide architects with a versatile insulation platform for creating high-performance building envelopes without sacrificing valuable space.
