A deep-energy-retrofit project uses Kooltherm as part of a high-performance attic insulation system
Improving the thermal performance of an existing attic is often challenging: workers are faced with narrow cavities, low clearances, and claddingMaterials used on the roof and walls to enclose a house, providing protection against weather. systems that make it hard to achieve desired R-values while still maintaining the necessary drying potential of the assembly.
