Well, we’re back at the construction process after a month in Thailand for Christmas! Before we left in early December, Kyle had put in a one-inch layer of rigid foam board insulation in the walls and ceiling. We had originally bought enough foam board to fill the ceiling, but after some more research, decided that spray foam wouldn’t be that bad to do ourselves. Since we had the foam board, the entire house got a layer of foam board.
After a layer of foam board, Kyle ran all the wiring for the electric and installed all the electrical boxes. The week after we returned from Thailand, Kyle, Zac, and Kyle’s brother Dean filled the walls with spray foam. Originally, we were thinking about hiring out the spray foam insulation, but Kyle’s a diy kind of guy, so why not learn something new? He used Foam-It Green, a diy kit he found online. The kit came with foam, sprayer, and protective gear. After a few hours of prep, including heating the house to above 60 degrees and covering the electrical boxes, the actual spraying process took about 4 hours, plus clean-up.
As we began putting up the wall material, we decided that there was still an inch gap in most places between the insulation and wall, so we picked up some loose fiberglass insulation.
Not the most conventional way of insulating a house, but it adds up to R 17. One inch of rigid foam board (7 R-value), 1 to 1 1/2 inches spray foam (7 R-value per inch), and 1/2 to 1 inch of loose fiberglass insulation (3-4 R-value).
It made for an exciting weekend!
