Spray Foam Insulation Question

Jen
10 years ago

We are almost to the insulation stage of our build and need to make a decision about spray foam insulation. It is VERY uncommon in our area (Idaho). Our builder has never used it and I don't know anyone else who has either to ask my question. We have a bedroom in our second floor that is entirely over a garage. We're having a geothermal system put in and that bedroom will be on it's own zone along with one other bedroom and a bathroom up there. The thermostat for that upstairs zone will be put inside the bedroom over the garage. So we're trying to decide if we should also put spray foam insulation in the garage ceiling and in the exterior walls around that room. It will cost an additional $1400-$1800 to do it. I'm wondering if it will help the heating/cooling enough in that room to warrant the extra cost. Any help or advice would be greatly appreciated!
