UAF Sustainable Village Week 17: the first cellulose REMOTE wall

This week we tried a new building system at the Village‚Äďa cellulose REMOTE wall in the SW house. A REMOTE wall has the majority of the insulation value, or R-value, outside the sheathing rather than inside. Up to this point, we always used rigid foam on the exterior. But since one goal of the Village is to test new techniques for both cost and energy use, we decided to try a REMOTE wall with batts as interior insulation and 9 inches of cellulose on the outside.

The house has two sets of studs, with sheathing applied to the inner wall. The inside wall cavity is filled with a recycled batt insulation. The outer wall was wrapped in Tyvek. To insulate the outside wall cavity, we hole-sawed a 6-inch hole in the sheathing in each wall bay (on both floors) and sprayed in 12 inches of dense-pack cellulose. Those holes were patched with poly sheeting and acoustical sealant. The whole wall is 18 inches thick.

We also installed birch paneling ceilings, cabinetry, and ventilation systems in 2 of the homes. The homes are mostly sided and are starting to look very livable!
