Questions & Answers

Can the R 38 Cathedral Insulation be installed in a 2x10 rafter depth and still be R 38 even though slightly compressed?

Asked by: Chuckster
No. There must be a 1" air gap. The thickness of the air gap and the R38 insulation is 11.25 inches. A 2x10 is only 9.5 inches deep.

Can I get R-30 in a 2x8 rafter space with vent shoots?

Asked by: JD
No. Vent shoot is 1", plus the R30 insulation thickness of 9.5", you need 10.5 inches. 2x8 is only 7.5 inches deep.

what is the best to use in a 2x8

what is the best to use in a 2x8
Asked by: john
Foil faced rigid insulation. The polyisocyanurate sheets are over R6.5 per inch; the 2" sheet delivers R13.1, so three of these stacked will provide R39 but only take up 6 inches. That leaves an inch for the air channel above. The seams should be tight, spray can foamed where loose, and taped with metal foil tape to provide a continuous vapor barrier. Home Depot sells 2" RMax Thermasheath sheets.

Customer Reviews

R38 Cathedral Insulation Kraft Faced Batts 23-3/4 in. x 48 in. (8-Bags) is rated 4.3 out of 5 by 3.
Rated 5 out of 5 by from Everything the vendor says about them seems on the mark.... Everything the vendor says about them seems on the mark. No itch. Hard to tell about insulation quality as I’ve just installed them but they are well built and appear to do the job. Only time and winter will tell.

Rated 4 out of 5 by from Have not installed it all but I like the product so far. It leaves an air space in the 12" I jois... Have not installed it all but I like the product so far. It leaves an air space in the 12" I joists I'm installing it in. Only issue so far is one of the bags only had 7 batts in it. Do wish this product was also available for purchase by the single 8 batt bag do reduce expenses on the project I am working on. Will need 1200 square ft of product or 3 pallets which will leave $660.00 dollars worth of unusable product in the end.
