Once we saw that the house had no wall cavity insulation, we had to improve that. We decided to increase the cavity depth from a 2×4 cavity to a 2×6 cavity. The small amount of time and materials to do this now is inconsequential when compared to the future energy savings and comfort level we will create.
Expanding the cavity depth and adding insulation took a few simple steps.
- Rip lumber to 2″ to use as the extensions
- Attach extensions to the existing structural members
- Install the insulation
