Insulation

[Raven]

@ Nebe?
i have a barn section that needs insulation bad
it's like a walk in freezer set at 20 degrees
so, if i have a company foam it
are the truss's coated too so i can cover up
the foam with say plywood and not see it?

My $.02.

1. You can typically pay someone for less than you can buy the batts. Before they or you install batts, use canned foam to seal any wire holes or pipes, etc. I prefer un-faced batts with polly vapor barrier but since you only have one bay stripped, it really doesn't matter.

2. If it were me, I'd strip the entire garage ceiling and warm walls, add wiring for what ever I could think of for future and have it sprayed with closed cell foam. They will spray to what ever depth you want. If you fill to the depth of the joist, you'll get something like R50. Walls you can get up to almost R30. It's usually 2.5 - 3 x the $ of doing batts.

Drove past Glastonbury around 7pm last night on my return leg from Philadelphia....

It is a budgetary issue. Batt insulation is not going to improve the cold you have been experiencing, unless you can install radiant heat from the underside of the floors. Foam would be first choice. Again, price dependent. Run all wiring and plumbing first. Add some PVC tube messengers for future use. Planning accessible shutoffs is key. And if you have to add wiring in the future that you had not planned for, it is a garage ceiling, so adding race tracks on the sheetrock will not be out of the question.

Foam fills the rafter bays, not the trusses. Google foam insulation and look at images.

foam it, it's the best hands down,expensive but the best.
