What about contact with o.s.b. sheathing?
Asked by: jj
Hi JJ, proper ventilation is always recommended. In order to have proper ventilation, you will need intake/exhaust vents and an air space between the insulation and the underside of the roof deck. Thank you for your inquiry!

R38 Cathedral Insulation Kraft Faced Batts 23-3/4 in. x 48 in. (8-Bags) is rated 4.0 out of 5 by 2.
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.
