Wall Construction Calculator

This calculator determines the overall insulation value and themal characteristics of a multiple layer wall construction and provides a temperature profile and estimated potential condensation plane location given temperatures and relative humidities on either side. It is intended to help clarify the benefit of moisture and vapor barriers or other management approaches. More information about cooler wall constructions can be found in our Guide to Cooler Walls.
