Unfaced

Unfaced insulation does not have a vapor barrier; used over existing insulation in the attic or where moisture control is not needed.

Answer This Question

A:  Hello Fred, The R-38 can be installed between floor joist, with it being 12.5" thick it will expand past the joist, if supplemental support is needed strapping my be best to prevent compression. You will also want to check with your local building codes to determine if a facing would be needed. Thank you for your inquiry!

          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. The insulation quality and packaging is excellent. Once the bundle is cut open, it expands to its 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.
