Building Science: What’s Inside a Passive House Wall?

April 16, 2015

Portland-based builder and remodeler Hammer & Hand built a smaller-scale model of the passive house walls they create for real-life projects.

Watch the video on YouTube and see what else goes into the intricate Passive House wall design.
