That's the inside of the foam truck. Yah. I guess, we were lucky, it wasn't too cold this Fall. Although, the last weekend of October was bitter cold with that freak snow storm. It was awefully cold actually, since the electricians were here that Saturday wrapping up the job, the power was shut off for most of the day, and I was trying to study.Luckily, we didn't get too much snow either, since most people were without power on Sunday and Monday and we had it. Brand new wiring in fact. Finally, on Wednesday we got insulation.
Since the older 1/2 of the house, has nominal 2 x 4 construction we had a closed cell foam sprayed in there. Which gives us an R-21 at the wall. The closed cell also is a bit more rigid and stiffens the walls up a bit. Which also helps. The new construction, roof and 2nd floor got the open cell foam, since it expands more, this fills the entire 2 x 6 cavity and doesn't allow air & moisture to convect or condense in the wall. We are already seeing a difference with the boiler in the older section of the house, not continuously running all day either. Already, we are feeling like the house is more efficient.
