Be aware that 12 bags of this insulation (all included in the purchase price) means you are receiving one HUGE pallet; towering over eight feet tall. I picked mine up from my Home Depot for free, but had to take it in two separate trips in my truck.
Working with it is very easy. I read a lot of reviews before buying and two issues that were repeated often were the dustiness of this product and the difficulty or ease of tearing it into smaller pieces (depending on who you ask). First; it really is dusty. But other than a few denim-colored boogers it didn't affect me. It wasn't a hazard to breath or anything like that. I did take to wearing a basic breathing mask (like the paper ones you wear at the doctor's office when you have a cold) after the second day just to keep from breathing it all in, but I am working in a very small, confined space that is hard to ventilate. Second; it tears really easily. About half of the batts are not perforated, and the other half are perforated in various widths. The batts with perforation don't have to be torn apart, but if you need to, it is VERY easy to do. I am working on a steel-frame house with 16" on center studs. These are designed for steel studs as they have to take up the entire 16" space (not like with 2"x4"'s where the wood itself takes up part of the 16"-- steel studs are just a couple millimeters thick so you need a batt 16" wide plus an additional 1/4" to make sure it's snug). Our steel studs are varying widths, especially around window, etc, so I have definitely used the perforations to get smaller widths.
To use: lay these out flat for a few minutes and shake each one vigorously to get it to "pop" out and be the full thickness needed.
I found it very easy to lay this insulation material behind all plumbing and electrical cords and then using my fingers, tear into the insulation along the cord or pipe and then just pull the insulation out and around said object so that the object was now encompassed fully within the center of the insulation, not in front of it anymore. I got lots of scraps working in odd-sized areas, but the scraps work well as loose fill too, so nothing was wasted.
Overall, this denim insulation is far easier to work with than the pink stuff, and non-toxic. A winner! I will be recommending this to anyone redoing insulation or working on a new build!
