It is a bit difficult to put on a ceiling by yourself, but the end result was very good. I did also get some 4 inch wide seem tape which really sealed the seems well and made it look a lot more polished. I needed to cover the exposed insulation on the ceiling and also on a couple of basement walls, and I'm very happy with the look of it.. Now I have to paint the foundation so it isn't left behind. :-)

Adding on a house with no insulation. Super strong, easy to put up. First month saved $300 on cooling bill. Roof is next

I used this to cover 6” fiberglass insulation in the walls and ceiling of my garage/workshop. The white exposed surface provides a nice clean look and improves the lighting situation in the space. This was easy to cut and staple during installation, but is remarkably resistant to unintended puncturing/tearing. The 4’ wide rolls were manageable as far as handling and maneuvering them during the install process, and that width allowed me to get everything covered pretty quickly. I purchased 4” wide tape to cover the seams, and there were no issues adhering the tape to this material. I can’t speak to how well it insulates, but I definitely recommend this as an exposed wall covering option that may also provide insulating value.

I used it in my garage to seal inside moisture barrier insolation mad it so dark this has white and a mylar side 2 it looks good and does the job..thanks

Not the best insulation obviously (it's a single layer of foiled plastic) but it's durable and helps reflect some heat
