Hi guys,
Great thread! Sealing the air leaks and insulating the attic is top on my to-do list - the car has to wait. I'll be sure to take pics and post. I used 1186 gal of heating oil last year here in NH.
On the Great Stuff, I read in Family Handyman magazine the Great Stuff is *not* fire rated and should not be used for service penetrations between floors. In some cases, it is against code to use it; check with your local building inspector to be sure. Use something that meets ASTM E-84 Specifications and classified as a fire-rated foam insulation.
Have fun!
