The spray-in foam insulation is done & you can already feel a difference in the interior temperature of the house. The house has only temporary doors & no garage door but the difference between the inside & out temperature is really quite noticeable. The exterior walls of the house have 2" X 6" studs, not the widely used 2" x 4" studs. This means that there is a whole lot more foam in our walls. Which translates to higher energy efficiency and lower heating & cooling bills. Or more money in your pocket and not the electric company's.
