It doesn't even seem to be a case of needing spray foam. Basically, there just needs to be some insulation in the attic over the garage (apparently it was either not done or not sufficiently done when the main attic was done) as well as the entrance hole to the attic also not being properly insulated. Otherwise, the house was pretty well insulated.
To be honest, I'm slightly bummed at the CFLs, but mostly because I've been going all LED recently. Still, they were freebies, so I'm not going to complain.
Oh, and I live down in Wrentham, since you asked.
