Insulation of Outer Walls

Insulation, Insulation, Insulation!

Once raised ¬†and locked into place with the outer row of anchor bolts, the 2×6 outer walls are completely insulate with Roxul insulation.

Then, prior to raising the second, 2×4 , inner, “load bearing” wall, we add another layer of 1.5″ thick semi-rigid insulated sheathing (ComfortBoard IS – R6). This layer provides a complete thermal break between the outside wall and the inner wall. This Roxul insulated board comes in 4×6 sheets and is tacked into place with skirted nails.
