Questions & Answers

If my house has 3000 sq ft how much will I need

Asked by: Barbara
it's not how many square feet your house is, it's how many square feet the attic is. Assuming your house is 1 story and the attic covers all of it, then you're looking at probably 1500 sq feet. If your house is 2 story then only 1000 square feet, etc...

I have a cabin 16ft x 32ft, how many bags would you suggest total for ceiling?

I have a cabin 16ft x 32ft, how many bags would you suggest total for ceiling?
Asked by: terry
1 bag of R-49 = 32 sq ft at 13.50" thick. Your cabin has 512 sq ft of space, so 16 bags of R-49 insulation would cover approximately 512 sq ft of your cabin while being 13.50" thick (or high).
