k2Table : Conductivities ( ) and Conductances (C) of Building and
Insulating Materials--Contmued
`
These constants are expressed in Btu per (hour) (square foot) (Fahrenheit degree temperature difference). Conductivities (A) are per inch thickness and conductances (C) are for thickness or construction stated, not per inch thickness.
