Prepping For Spray Foam

Well, the addition foundation is almost complete, the new sump hole is ready, gravel is laid and the concrete should be poured in the next day or two. We saw some window framing started and they have begun strapping the exterior walls in preparation for the spray foam.

We had a Certified Energy Audit performed in April in order to qualify for some of the government grants on home improvements. It was an interesting process and we learned quite a bit from the auditor. Specifically, that it is more efficient to insulate the outside walls rather than the inside walls of the foundation, in fact the grant will not assist with the cost of insulating the inside. This is so that the frost cannot penetrate the foundation walls, makes sense.

I will scan the results for the energy audit some time next week and post it, it is interesting how well the old house did, how it is broken down and what is covered and how much.
