how many batts are in the package

Asked by: mattielord7777777
i believe there are 16
Answered by: Anonymous
Date published: 2020-10-30

For attic insulation, Are rafter vents necessary before placing insulation even though there are no open soffits for venting? Also how deep is R20?  For what application and R value?

Asked by: Dee29
All insulated attic spaces must be vented or condensation issues could occur. Half the vents should be located in the soffit at the bottom of the roof and half in gable or ridge vents near the top. Both roof and soffit vents are required to create a positive air flow. R-20 batt insulation is +/- 6" thick depending on brand and type. R-20 is used in walls, roofs and floors, sometimes installed in multiple layers in roofs to achieve a higher R value.

Johns Manville R20 Unfaced Fibreglass Batt Insulation 78.33-Sq. Ft. Attics and Floors is rated 3.8 out of 5 by 5.
Rated 1 out of 5 by from Awfully thin for 6" batts Needed 1 pack to finish a job I had been using pink insulation for. This 6" Johns Manville was really thin compared to the 6" pink stuff I had been using. I figure I am going to take a couple of batts and peel them into 3 thin pieces to use to thicken the batts to get the thickness I need for 6" studded wall.
