Why do R-Control SIP Structures out perform conventionally constructed buildings and homes with the same R-Value?
A. The R-Value Rating of a specific material or wall assembly was not intended to be the measure of the thermal efficiency of a home. R-Value measures resistance to heat loss by conduction. Other forms of heat loss are convection, radiation and especially infiltration (leakage). Conventional framing will batt insulation promotes convection, radiant and infiltration heat loss.
