Customer Reviews

Insulfoam 3/4 in. x 2 ft. x 4 ft. R-2.89 Insulating Sheathing is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Exactly what we needed Installed in ceiling of enclosed porch. Matched the existing tiles exactly.Since it's made of foam material there was some cleanup from bits that came off.
Date published: 2015-01-20
Rated 5 out of 5 by from Works well The insulation works well, given that it is only 3/4" thick. The Reflective foil on one side of the insulation really makes a difference and reflects some heat, so that one can go with a thinner piece than one normally would. Easy to cut and to work with.
