We are preparing to introduce an expansion of the WarmFörm product offering – new face thicknesses to meet the demands of the Passive House standard. These new elements will be available in a 4″ face, 6″ face, and 8″ face. Note these Passive House Elements have no beveled top edge like the standard WarmFörm Elements in order to match up with thicker exterior insulation layers in wall assemblies. R value varies per temperature, but the foam manufacturer’s Design Thermal Resistance per inch for this Type IX foam is R 4.8/inch. So face R value at 40deg F for these Elements is 4″ R19.2, 6″ R28.8, & 8″ R38.4.
