Review: Good quality - Worked well for under hood insulation. I used plastic rivets to hold it in place and aluminum tape to seal any place that i had to use more than one section.
Review: Stick it up to keep the noise down! - I needed to replace the failing fiberglass insulation that was original in my 1996 motorhome. The original insulation was providing some sound/heat protection inside of my generator cabinet but it was falling apart. After cleaning off the failing insulation and adhesive, this new insulation seemed to stick well to the interior cabinet walls. I could easily cut this insulation with my scissors but it does make the backing paper try to shred at the cut edges instead of peeling off in one motion. Just being careful I could ensure that all of the protection paper came off to allow full adhesion to the metal walls. It was fairly easy to attach and turn corners. NOTE: this item could probably be stretched to the advertised 40" x 40" but I wanted to install it in its relaxed size of 38" x 38". I had plenty to cover the inside of generator cabinet fully. It did reduce the noise some from my generator. I guess I could also install more of this insulation on the outer walls of the generator quieting down even more of the noise inside my motorhome. So far it is sticking well but if things change I will edit my review of this product.
