The insulators are hard at work installing the bats for our Seattle basement remodel. Yesterday didn’t work out as planned, but the contractors showed up later in the day to haul all the insulation from the driveway down to the basement.
The original plan when talking to Ryan was to have the majority of the basement insulated using Roxul, and the portion that was beneath the exterior deck was to be spray foamed. Ryan has since informed me that the inspector would not allow the exterior deck portion to be spray foamed. The reason behind this, is that spray foam is not permeable. If any water were to leak through the deck, the leak would not be discovered until that area was rotted.
At first I was concerned about not using spray foam, since I have been told that it is the best form of insulation. Although, once Ryan told me that we would be experiencing the same R-value and better noise cancellation, I was convinced that this option was sufficient. That being said, the duration of insulating our basement remodel here in Vancouver will be shortened, as we no longer have to schedule spray foam insulators.
