Questions & Answers

I'm looking to install these insulation boards to a finished dry wall closet....the easiest way for me would be to use an adhesive bond ...like liquid nails...would this be sufficient bonding to the wall ?
Asked by: mrgolf535
It should be sufficient. These panels are very light weight. They are also 4ft wide which I believe is less than standard distance between wall studs so you can also cut these to fit between the studs and press them in for a friction fit.

Asked by: arwen
yes, If the silver side is in direct contact with the glass put this side to the interior of the room to create an additional radiant barrier. If you have more questions please contact our technical department at 972-850-3604 thanks.

Thermasheath Rmax -3 2 in. x 4 ft. x 8 ft. R-13.1 Polyisocyanurate Rigid Foam Insulation Board is rated 4.8 out of 5 by 74.
Rated 5 out of 5 by from This rigid foam insulation board was purchased to insulate my... This rigid foam insulation board was purchased to insulate my kitchen floor from the cold air that comes into the crawl space underneath. It has an R-value of 13 with just 2 inches of depth. (Two layers together have an R-value of 27.) The expectation is that this winter my kitchen floor will not feel like an ice rink. The material is easily prone to gouges if you run into anything pointed, so be careful handling it. I recommend purchasing a piece of plywood to act as a protective cover for tie-down on your vehicle when bringing it home from the store. The material is easily trimmed to fit any space with a narrow sharp blade - I created a cutting tool by sharpening a wide steel putty knife and wrapping the area where the steel goes into the handle with cloth tape in order to keep from cutting my hand. I fastened the sheathing in place with 3" screws and 1.25 diam. fender washers. Don't forget to purchase the roll of metal tape to seal the seams.

Rated 5 out of 5 by from R13 in only 2 in. I purchased this rigid insulation to insulate a cinder block basement wall. The sheets were easy to cut and I achieved R13 in only 2 in. of space as compared to extruded polystyrene, which is only R10, and for the same money. My only disappointment was that I planned to use construction adhesive to install for the short term, but this stuff had a slight bow from the store shelf and the polyiso it is too rigid for the adhesive to adhesive to flatten it out, so I ended up using furring strips and 1/4" x 3-3/4" flathead Tapcons to anchor to the block rather than adhesive, which was my long term plan anyway. Not the products fault, but thought you should know how it behaves. Also, tape the seams with the nashua foil tape and fill any large gaps with great stuff (same polyiso product).
