Will Double Stud Wall Construction Bring Efficiency at a Modest Cost?comments (15) January 13th, 2011 in Blogs
Double-stud exterior walls are easy to build; they use affordable,common materials; and they can hold a lot of insulation
If building on a budget seems a common goal, Karen Bean's situation gets more complicated. She has inherited the foundation on which the house will be built. Designed with more traditional construction in mind, the foundation is in good condition and looks to be well made. But can she adapt a double-wall design to fit it?
Double-stud walls can be a cost-effective way of achieving energy efficiency, but suggestions soon follow for a modified Larsen Truss wall system. These foot-thick walls, packed with cellulose, offer high R-values and minimize thermal bridging. Plus, cellulose insulation has some advantages over the blown-in fiberglass Bean has been considering.
As to costs, enlisting friends and family is one way of keeping the budget low. But material choices also play a part. Using rough-sawn lumber from a local mill, and finding a source for salvaged insulation, also will help. So will keeping the house simple, and maybe a little smaller.
