Based on its own videos, the Arizona-based maker of recycled-denim Ultratouch insulation still doesn't get it when it comes to installation quality.  What do you do when a green product doesn't live up to expectations? Here at BuildingG... I also found that the batts were too wide for 16-inch-on-center KD 2x4s (standard lumberyard kiln-dried sticks), leading again to air spaces due to poorly fitting batts. Thirdly, I complained that the batts were really hard to cut. This was especially frustrating because the ill-fitting batts required a lot more cutting than a standard fiberglass batt. The good news is that Bonded Logic is now perforating its batts at standard widths so that they are easier to cut for proper fitting. They haven't announced what those widths, are, however, and it seems like a tough problem. How standard are the sizes of the off-size stud cavities found in our buildings? Perhaps in new homes with designs optimized for manufactured material use they are standard, but in the retrofits and custom jobs that a lot of builders are doing today, I am not sure how useful these perforations will be. Another piece of good news, according to a spokesperson I heard from, is that Ultratouch will also soon be available in different widths according to whether you're using wood or steel studs. Bonded Logic still doesn't get it However, Bonded Logic still doesn't seem to get it when it comes to installation quality. Whether you're using fiberglass or cotton batts, exact fitting to cavity sizes is key. That means cutting insulation around electrical boxes, wiring, and also cutting it for the occasional cavity of a different dimension. What I've seen of this installation video is pretty good, but there's a flub in the Bonded Logic video publicizing its new perforated batts . As the screen capture shows, the installer is placing a batt in a cavity with complete disregard for the unusual shape of the cavity. The installation will result in a classic poor batt installation--lack of complete contact with all six sides of the cavity. What kind of attention are they putting into other irregular cavities? I brought up this issue with the same Bonded Logic spokesperson in two successive emails, and did not receive a response. That was a couple months ago. The video is still up, so I'm taking Bonded Logic to task again. The real installation culprit: fiberglass To be clear, I like cotton insulation for several reasons, including Bonded Logic's recent move to post-consumer recycled jeans (previously it was pre-consumer denim), and the fact that it's much less unpleasant than fiberglass to work with--although unlike the folks in their videos I would still wear a mask to protect from dust that comes off the product, particularly during cutting. Also, the real culprit in batt insulation is fiberglass, which has been poorly installed by so many people in so many buildings for so many years--to the extent that one observer called for it to be banned . All the more reason, though, that we need to do better in the green products community. What do you think? Please leave your comments below.
