Time to look at Part 2 of our video series on building Nordic style walls in the US. Today we look at the USA New Wall, and its Good, Better, Best versions which make it easier for American builders to step into high performance building.

In the first video, you may recall, we briefly reviewed why we would look to Sweden to inspire the way we build houses in the US. This next video shows how we can apply the lessons from their wall construction to building here in the US. We offer these improvements in easy to achieve steps. First get familiar with better insulation, then introduce a wiring space to your walls to make it easier to keep the house air tight, then complete the picture with an exterior insulation layer that makes a good thermal break for the wall framing. Here is Part 2:


This video piece shows how to go about building Nordic Style walls for residential construction, like the walls used in Sweden. We call these American versions of Nordic walls the USA New Wall.

The wall systems have been broken down into Good/Better/Best subsets in order to offer builders a gradual path to increasing the performance of the walls they build. The video starts off with a detailed look at a typical Swedish wall, and then walks you through the Good, Better, and Best versions of the USA New Wall.

The USA New Wall is explained in much more detail on our web site, and you can read that on this page:

You will note that all of the wall variations feature Stone Wool insulation rather than fiberglass. We mention in the video that this is because Stone Wool offers higher insulation values - R23 for 2x6 stud spaces, and R30 for 2x8 stud spaces. We also mention that it allows for better installations. You can read a detailed article about why this is so on our blog:

Also mentioned in the video is the Variable Permeability Vapor Retarder membrane. There are several sources for this unique vapor retarder, notably Certainteed's Membrane:

And Intello Plus, and DB+ by ProClima:

You can read the entire Letters from Sweden series on the blog.

The USA New Wall, and Swedish Platform Framing are an outgrowth of our research into Swedish building practices. Again, you can find details of the USA New Wall here:
