Understanding Your Walls

Walls typically represent the largest exterior surface area of a home. So, from an energy standpoint, the wall system is the most important part of the building envelope. There  are many ways to construct an energy efficient wall, including various types of structural framing, insulation, air and vapor sealing, and more.

At the Cold Climate Housing Research Center, we test new building techniques and materials to find the most cost-effective, durable, and efficient options for homeowners. Many factors need to be taken into account when designing or choosing a walls system, including local climate, cost, access to materials and equipment, and much more.
