What started out as a very poor insulation for a  roof in a cold climate (R 19 batts in a 2×6 rafter bay, largely fallen down in the past 70 years) is being made over as a model of energy saving performance. In this photo you can see the polyisocyanurate nail base beginning to be installed. From the inside 5 1/2″ of polyurethane spray foam will be applied to seal any air leaks and raise the overall R-value to R49! This house is similar to the 1940’s era housing stock we find all over Aspen, Basalt, Carbondale and Glenwood Springs.

Here at Confluence Architecture we have been working on a couple of “gut-rehab” “deep energy retrofit” projects. Now is an exciting time because they are turning the corner- demolition is over and construction has begun! This house located in Glenwood Springs, Colorado had serious summer over-heating problems. The photo shows new properly sized overhangs on the south.
