Insulation began today. We purchased 1800 board ft. of spray foam insulation from Tiger Foam. It is a DIY insulation so we were a little sceptical, but when comparing prices to a professional outfit we took the gamble. Although I wasn't able to be there for the spraying, Joe reported that it went pretty smoothly! It came with a big sigh of relief on my end of the phone in Brazil...

We decided to use spray foam insulation to give the house an air tight seal. Although commonly used exclusively, we made the decision to spray 1" which will give an insulating value of R-7 and then fill the rest of the wall cavity with R-14 fiberglass insulation. This will provide us with the tight package of spray foam while keeping costs down.

One drawback with having such a tight house is the "breathing" properties are cut off. To compensate for this we purchased a heat recovery ventilator. It is an air exchanger that will replace stagnant air in the house with fresh air outside. It has a small heat exchanger built in that uses the heat from the outgoing air to heat the incoming supply air, thus eliminating cold air infiltration in the winter.




Any front door color suggestions?? Right now we are thinking black...
