k-FACTOR

Thermal conductivity for a unit thickness of material. Expressed as W/m2•K (Btu•in/hr•ft2•F). R-VALUE (see also) is equal to the thickness of the material divided by the k-factor (R = x/k where x = thickness).

SPFA believes that the path to a healthful, safe, high-quality and performing SPF installation travels through the hands of a knowledgeable, trained, experienced, and ideally PCP-certified professional contractor.
