12/20/2012: Insulating exterior walls

Having our exterior walls insulated this week through Mass Save & Green Stamp Insulation. The process is pretty simple: Green Stamp removes a piece of siding and drills a 2″ hole in each stud bay. Cellulose insulation (shredded newspaper, cardboard, etc.) is then blown into each bay. The hole is capped with a styrofoam plug and siding put back in place.

Cellulose insulation will help reduced heating & cooling costs by 30-50%, control mold and help keep bugs out. Total job cost was $4,600 — with a $2,000 credit from Mass Save, it was only $2,600 out of pocket.
