DOUBLE STUD-WALL OPTION
We are pleased to announce our double stud-wall option, which will greatly increase the amount of insulation you can put in your walls, and substantially reduce thermal bridges. This is a very cost effective way to reduce your heating and cooling costs.
Our optional double stud wall system is designed with two 2 x 4 exterior walls, separated by a 5 gap between the studs. This proven construction technique creates a 12 exterior wall, and will allow you to achieve an R-value of 40, using relatively low cost and easy to install fiberglass batts.
The advantage of the double stud-wall, beyond the obvious extra insulation allowed by the increased depth of the wall, is that there are few, if any, thermal bridges in the wall. A thermal bridge is created when a component in a wall with a lower insulating value, such as a stud, extends from the interior to the exterior of a wall. In the typical 2ื6 stud-wall, the studs create a thermal bridge, because the wood has an R-value of only R1 per inch, or R6 in total. This thermal bridging creates spots within the wall that will conduct heat much faster than the rest of the wall causing cold spots. .
Using a double stud-wall is a good method for getting a lot of insulation into a wall if you are doing your own construction, as it is simple and the materials are relatively inexpensive and proven.
