Cost-effective insulation approach for unvented attic retrofit?
Looking for the most cost effective way to increase the insulation in my attic.
Some info on the house:
-Single family ranch approx 2500SF, built in 1970s, upstate NY CZ 5A
-Vented attic with fiberglass ceiling insulation approx R-30
-Central air handler and ductwork located in attic
-Stick framed roof
I’m thinking of possibly fastening foil-faced rigid foam to the rafters. Preferably do not want to deal with cellulose or anything messy as there is no real air barrier and the attic is used partially for storage.
Any feedback would be greatly appreciated!! Thank you in advance
