9' x 37' = 333 square feet so you would need 333 sq ft of material, which is 5-6 bags worth.

I have a Tuff shed that is 10 x 14 pitched roof. Center is 10 feet high.How much insulation do I ...

Asked by Ferri August 27, 2019

Answer

If you are looking for coverage, then using R15 Kraft faced 15” x 93”, 10 bags at 67 sq. ft. per bag should provide sufficient coverage inside the shed including the roof. Please keep in mind that Kraft-faced should not be left exposed. Kraft paper should be in substantial contact with dry-wall or other substrate. If you are not heating/cooling the shed, then insulation alone would not help you achieve comfort. Also, IRC/IBC does not require insulating of the unoccupied spaces.

How thick. I want to insulate a tool shed with 2x4 walls not 2x6. Thanks

Asked by Scott September 30, 2020

Answer

This product works for 2x4 walls and is the correct thickness for your project.

I need 2x4 walls and 2x6 ceiling. About 350 square ft room. Would this 10 bags would be enough?

Answer

Hello Nick, Thank you for your interest in Johns Manville's fiberglass batt insulation. The product that you are referencing has a coverage of 67.8 square feet per bag. Assuming you have 8 feet walls and you are insulating all four walls and the ceiling, you would have 960 square feet to insulate. This would take approximately 14 bags of material. Best regards, Doug Fast

Is there any problem using this in garage walls where the framing is on 24: centers?

Answer

This should be the correct product for your framing. When sizing the insulation you should make sure you are completely filling the cavity.
