the goal

This was the ultimate building performance upgrade. The Pan Abode house, a cedar log home with factory manufactured components, had no air sealing or insulation and was super drafty. The home owner had been slowly increasing the efficiency of the home by adding ceiling insulation, new windows, solar panels, a heat pump and a tankless water heater but the home was still cold and drafty.

project details

We consulted with Lee Laney, an Energy Advisor at the Community Energy Challenge, and Albert Rooks, President of the Small Planet Workshop, about the best solution for this building performance upgrade. Everyone agreed that wrapping the entire home in a weather resistant barrier and adding Thermacork for exterior insulation was the best strategy. Additionally, we completed extensive air sealing and added a weather resistant barrier.

There are a few product and sourcing details worth noting, include the SIGA house wrap, Thermacork insulation and cedar siding.

  • We opted to use Thermacork insulation on this project for a number of reasons, one of which is that it is a carbon negative product. Check out this video to learn more about how Thermacork is made and why it’s so great.
  • The SIGA products we used on this project are pretty standard tools in our kit. That said, it’s worth mentioning that we used the SIGA tape and the Majvest weatherproof membrane.
  • The cedar siding was harvested and milled locally by Greenleaf Forest Products.
