What is the difference between U-factor and F-factor and between U-factor and C-factor?
What will be an ideal response?
The U-factor refers to the U-value of a component that is exposed to air on both sides, such as an exterior wall or
exterior door. The F-factor and C-factor relate to U-values of assemblies that are exposed to air on one side and ground on the other side. F-factor relates to concrete slab on ground and C-factor relates to below-ground walls, such as basement walls.
