CCHRC members and sponsors provide vital, sustaining support for our mission to promote and advance healthy, durable, and sustainable shelter for cold climates. Donations help fuel many projects, including sustainable prototype houses in rural Alaska, renewable energy tests, and the production of educational videos, publications and multimedia. Your contribution to CCHRC makes change happen by providing valuable support to our research efforts.
Walls typically represent the largest exterior surface area of a home. As a result, from an energy stand point, the wall system is a major component of the building envelope, particularly in extreme cold climates. When it comes to improving thermal performance, there are many ways to construct a wall, and the details of sealing, sheathing and insulating are even more numerous. At the Cold Climate Housing Research Center, various wall types and building techniques are being evaluated on an ongoing basis. There are many factors that must be taken into account when designing or choosing a wall system: Energy efficiency, cost, resistance to the elements, availability of materials, and the climate in which the wall is expected to perform, are all important considerations.
