Last Friday (2008-09-26) the house was spray-foamed! This is a polyurethane closed-cell foam that is one of the best insulators out there. We got four inches of foam in the studs up stairs, and two inches of foam in the 2x4 furring down stairs. Translation: the house is very air-tight and very insulated. The boiler with a couple of
unit heaters on it can keep the house quite cozy.
We spent the last week cleaning up after the foamers (studs have to be cleaned, random foam overspray, etc), removing the rest of the sheet rock on the upstairs ceiling, and sweeping/vacuuming up the aforementioned mess. Save the stairs we're redoing, no more demolition!
It's coming along nicely. Stay tuned for more!
