Amazing product this is the standard for high performance insulation. Very easy to work with for my first time,score and snap like drywall or use very large dewalt razor knife and straightedge to cut all the way thru. I taped seams using 3m 8088 or Siga wigluv and fastened with 3.5'' deck screws and Rodenhouse Plasti-Grip ci Prong Washer. It should be available at every HD but its not. Closest in stock HD to me was 1200 miles away so I drove and got a full penske truck load. 1 pallet special order minimum at my New Orleans HD and $13more per sheet not cool! But its the best price thru HD for polyiso anywhere.

Rated 5.0 out of 5.0 by Livestrong1003 Good product
I insulated a laundry room with the R13 foam board and the job came out great. The cold room is now warm. Much easier than framing and sheetrocking. It is still hard work to move all of the electrical and plumbing, but was made easier using Sharkbite couplings. Not so bad. Homeowners were very pleased with the end result. Material is strong enough to adhere strips of wood for shelving.
Tape seems with clear tape. Adhere to wall with large construction adhesive. Much more cost effective over spray on foam.
Use hand saw to cut material. Cut outside as there will be thousands of foam particles that will fall off. I will use again.
Material is waterproof and is reflective on both sides. A plus.

Rated 4.0 out of 5.0 by twoankhs great material
very rigid product, easy to cut with a jigsaw. Used between existing joists and easy to press-fit when cut properly, no fasteners required. Cooled room by at least seven degrees over the batt insulation it replaced. Foil took a chalk line well. Easier clean up than coarser foam board, less static. It was pricey, but the thickness saved me a lot of install time.

Rated 5.0 out of 5.0 by vthokie 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).

Rated 4.0 out of 5.0 by Mario Good material. Installs easy
Installs quite easy.
Use extra fine tooth wood saw to cut to size.
When picking up material from store INSPECT IT for damage to the corners and sides!
The do not pay much attention to the fact that this board is quire fragile and it gets damaged easy if mishandled.
REMEMBER YOU PAY $35!!!!! + TAX A PIECE FOR THIS STUFF!
