Here is a tool for architects and builders to compare relative performance characteristics and relative cost of residential wall systems within various regions of North America.*
Choose from 11 to 14 pre-configured wall systems in each of 5 different climate zones in the United States; and 10 wall systems predominately for the very cold climate areas of Canada. You can immediately compare on a good-better-best basis, fundamental performance characteristics using different claddings, insulations and interior membranes.
Compare wall system performance within a climatic zone for:
interior and exterior vapor permeability
and air infiltration resistance.
Our model assumes using durable plywood sheathing and mold- and moisture-resistant, fiberglass mat interior drywall. We drew our map based on the North American map for the hygro-thermal regions, developed for the International Energy Conservation Code (IECC), an initiative of the International Code Council.
