how many pieces per bag and total of sq feet??

how many pieces per bag and total of sq feet??
Asked by: Handyman
If you need 971 sq feet of insulation divide it by 42.67 sq feet per batt that equals to 23 bags.

Hi, I need to cover 3,050 square feet of ceiling, how many bags do I need?
Asked by: Pabloylucy
There seems to be 64 square feet per bag. Since there are 8 bags, that is a total of 8 x 64 = 512 sq. ft in the 8-bag package. To determine the number of packages you need, we compute 3,050/512 = 5.96 or realistically rounded to the nearest unit, you will need a total of 6 packages (that each contain 8 bags).

How many bags of this insulation would I require to cover 1740 sq ft of attic space?

How many bags of this insulation would I require to cover 1740 sq ft of attic space?
Asked by: Lilian
Each pallet covers about 512 sq ft. So you will need a minimum of 3 pallets (~1500 sq ft.). I would caution you on buying the 4th pallet. I purchased 3 pallets and had about 1/2 pallet leftover and when I tried to return the 1/2 pallet, I could NOT. I was told that the pricing was per unit (1 pallet), therefore, I would need 8 bags (1 pallet) to get a full refund.

Actual Depth?

General description says these are designed to fit 2X10 rafters, yet the product specifications say the material is 10.25" depth. Given that the actual depth on our 2X10's is only 9.25" in some cases, how will this insulation work, and still leave air space for our soffit to ridge-vent cavity?
Asked by: AllMyFault
relaxed depth is 8 inches

R-38C Kraft Faced Fiberglass Insulation Batts 15-1/2 in. x 48 in. (8-Bags) is rated 4.7 out of 5 by 113.

The house we purchased only had about 3 inches of insulation, and our summer electric bill was about $400/mo. Upon install, we noticed an immediate difference in the indoor temperature and how often the AC unit was turning on. Now, with colder weather kicking in, the house sits at 74 with the outdoor temp at 47, and the heater rarely turns on. Our bill this past month was $114 vs the $189 it was when we moved in. Given that we bought this as a Special Buy of the Day, we got it at 40% off and this will pay for itself in about a year. We broke down blown insulation bundles to fill the voids in the existing insulation (up to rafters), faced to cover the parts where there was no existing insulation and unfaced to top it all off. This insulation quality and packaging is excellent. The plastic wrapping is though enough to withstand the tugging/pulling of just getting it where it needs to be without tearing. Once the bundle is cut open, it expands to full dept quickly. If, like me, you're doing the install yourself, make sure to have a helper because each bundle is fairly heavy and bulky for one person to safely get up into the attic. I'd also recommend the ($10) Grip-Rite Stone Wool Insulation Knife because it cut through this insulation like butter and was priceless for this job.
