Its friday so it must be time to show the latest video in our Series about building high performance walls like the Swedes do. In our first video we explained why it makes sense to look to Sweden for a direction for our house building techniques. The second video we reviewed the Good/Better/Best model for easing builders into high performance wall building. Today we look at Swedish Platform Building, the best advancement in house building since the Western Platform Frame. Wow, is our house nerd showing here or what?

I've been trying to keep these videos short, and make them just an introduction to the ideas presented. But for the Swedish Platform Frame I was not able to do a short video. What happened was I ended up making a 3d model of the prototypical Swedish Platform Frame, and it was obvious that this was such a good way to explain this that I decided to just go ahead a make a detailed description of the framing system. So it is almost 20 minutes long - my apologies. Stop at the restroom, get a large popcorn, turn off your cell phones, note the exits, and prep yourself for the Director's Cut of the Swedish Platform Frame...

This video piece is about how Sweden has modified the Western Platform Framing method for better energy performance in residential construction. We call this modified framing method Swedish Platform Framing.

This video is quite long, and we apologize about that. If we figure out how to say all this in a shorter video we'll produce a new version. In this video we make a very breif review of the history of stud framing systems - Balloon Framing and Western Platform Framing. Then we proceed to look in detail at the differences between Western and Swedish Platform framing.

Swedish Platform Framing is explained in much more detail on our web site, and you can read that on this page:

As with the USA New Wall, the walls shown in this video use 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:

Not covered in detail in the video is the Vapor Retarder membrane. We prefer a 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:;=70_71_98_97_...

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:
