A project with a quantifiable energy consumption change…
We are currently in the middle of an interesting project. The project entails the removal of existing cedar shake siding, removal of gypsum sheathing (no vapor barrier!) and the installation of new insulation, new 1/2″ CDX Plywood, Tyvek, 3/4″ Foam Board, Type D Tar Paper, and then Stucco/Fiber Cement…
There will be a small addition (approx 180 SF) that will be insulated with Spray foam insulation.
We will also be sealing off all of the hi-hats in the attic with metal duct and foam, and air-sealing the house to the best of our ability. We have done the ” Before” blower door readings, and will report back with the “afters” as soon as the project is complete. We feel that there will be significant descreases in energy consumption; come back and see!
