Are they going to put flashing up along the dormers?
We applied 6" of closed cell on the underside of our roof only. 3-1/2" of closed cell for the exterior walls. No vapor barrier. I have been very happy with the results. The main thing people underestimate with foam is how well it seals the home if done correctly. We have a 27' great room ceiling, 32 large windows, 7 exterior doors, and a see thru glass fireplace from the living room to outside. Our home blower door tested at 1.9 Ach50. We are heating a total of 4,700 sq/ft with geothermal (1st floor, 2nd floor, basement). Our heating bill this winter from Nov through the end of this Feb was $540.
I definitely like the spray foam in the walls as long as you are confident on your wiring to cover future needs like entertainment system. Hate to think about trying to fish wires through that. For ceilings I would go with as much blown in (or batting) insulation to get max R value above you.Congratulations on your new house Justin. As you know, there are a lot of options when it comes to insulating it and they all come with different cost. I would also suggest that you take a serious look at spray foam as there are a lot of benefits over the other options.
Your better closed cell foams have a built in vapor barrier. Wow, 1.9 is really good.
I really like the idea of spray insulation, but it just isn't in the budget. We are about maxed out as it is. I can almost guarantee that this will become a "I wish I would have done that" down the road....I definitely like the spray foam in the walls as long as you are confident on your wiring to cover future needs like entertainment system.
