Rated 4.0 out of 5.0 by nasnan3 Nice and thick, easy to handle.
I am experiencing heat gain and excessive noise on the first floor which is emanating from tenants in the basement. Previously 1/2" rigid insulation was installed which did absolutely no good whatsoever, I could hear voices clearly and the first floor was now hotter than the second floor due to the heat rising from basement so I decided to try the thickest rigid insulation I could afford and re-do the entire basement ceiling again. These 1 1/2" sheets are lightweight and were easy for an old woman to cut and install. Does it do what it was intended for? I'm going to say yes because I like to think that after spending $200.00 for anything it works perfectly... but honestly, it's too soon to tell.

Rated 5.0 out of 5.0 by Casso Great garage door insulation
You can tell the sound difference with this insulation, the doors now sound solid when opening and closing. The 1.5 inch was the exact fit in thickness; I wish I would have done this sooner. I was surprised as how good it came out and how easy it was not to mention the ease of cutting the insulation with a regular sharp knife.
(6) 4x8 sheets will insulate (1) 16x8 and (1) 7x8 doors.

Rated 5.0 out of 5.0 by Daveyd007 Great stuff...fun to work with
I insulated my 6' X 12' enclosed cargo trailer every inch from top to bottom with this stuff, and was very impressed after I mounted a 5,000 BTU AC on the back door. It's like a walk-in cold storage freezer. lol
The air condition unit now runs for approximately two minutes or less at every fifteen minute interval as opposed to nearly continuous 24/7.
Sound proofing characteristics of this product are what I consider to be moderate to very good as well. As each panel went up I could notice the difference as it gradually eliminated an 'echo' throughout the trailer.
Could not be happier. Excellent value per sheet. Fun to work with. I used a six inch 'utility scraper' razor blade to cut it up. :)

One side of this board is aluminum which will not be cut with a hot wire. You would have to strip off the aluminum backing. Using a circle saw is okay, but I put the blade on backwards to minimize the shredding as the "styrofoam" like product can be messy. Also, be sure to use a blade with as many teeth as possible so you are not ripping up the foam. Hot wire will work with the pink foam insulation

Rated 1.0 out of 5.0 by Jerry Cannot cut to fit a pre-fab garage door
if you're looking at this to insulate your uninsulated garage door, keep looking. pre-fab uninsulated garage doors have recessed cavities that you would think you could slide this into for a good solid fit. you can't. if you cut to fit it won't slide into the cavity. So if you cut it shallow you are effectively floating it on the door for looks as it will leave a large amount of open space so you lose effective insulation. wish I hadn't wasted so much time trying to make it work but at least it was only $20 down the drain.

Rated 5.0 out of 5.0 by Rocky Just what I was looking for
I got this to insulate my steel pole building. It went up easy and is very easy to handle. Much easier than rolled insulation and more durable, in my opinion. Used dry wall screws to attach it to the horizontal 2x6 supports. I used fender washers to prevent the screws from pulling through the insulation. I also was able to cut it to fit into the panels on the steel overhead door. Did not need to glue them in since the cross supports hold them in place so they kind of "free float" in that space. The only minor complaint is that when you cut it into small shapes, the plastic sheeting sometimes peels off.

Rated 2.0 out of 5.0 by Brad Wrong description
The sku number for this product and the description do not match, at least at my store. They were not selling R-max 1.5 ", rather some pressed Styrofoam product. I went with the 1.5" pink rigid board.

Rated 5.0 out of 5.0 by john1943 good stuff
I've used a fair bit of this with success. the 1/2 inch size is great under large fish tanks (60 - 100 gallons). gives very even support and heat retention. Also 1.5" in external doors. Just a question, Ed, I've only ever used a utility knife but you say a circular saw is dangerous, but do not explain why. Why?
