Rated 4.9 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Easy to install and works great - but not very straight This stuff rocks! Crazy easy to install and works really well. The only downside is they are not 100% true and don’t align tightly together all the time (tight at the top and bottom but gaps in the middle) “JointSealR” tape worked great for this but hard to find “buyinsulationproductstore” had it, pricy! but works great. The temperature in my basement is almost too warm now and it’s below freezing outside :) January 18, 2015
Rated 5.0 out of 5.0 by Easy Installation Ok let me start by saying I am a 45 year female, and my daughter (16) and I did this alone. My basement is extremely cold, and this year the weather in NY was extremely harsh, and my pipes kept freezing even with them being wrapped in foam insulation. My basement is complete, and has heat, but it still remains chilly. When the basement was completed the contractor, made closets for the piping and a room where the oil tank is, but he did not insulate any of the closets for the outer wall . The boards are easy to cut, I used a jig saw, which saved the cutting time tremendously. I used Loctite grab adhesive PL 375 heavy duty construction adhesive to hold the panels on the wall. Since the areas I was attempting to insulate are very small, I had to cut the boards in half (across by the width), to make it easy to maneuver. My daughter placed the adhesive on the back of the boards using a glue gun and I just pushed the boards on the wall. I did not need to use cement screws. The product is easy to install and extremely easy to work with, actually it is a one person job. There is little if any clean up, and no itching from the fiberglass once cut, and for those reasons, I gave it 5 stars As for the insulation, I am not sure how good it will work, but I still kept my rating. I also plan on purchasing the door draft guards to place on the bottom of the door, and I am hoping that will make the basement much more cozier than it is now. If I am able to update this review in the winter, I will say whether the chase closets seems to be a little warmer. July 1, 2014
Rated 5.0 out of 5.0 by Owens-Corning 2-inch rigid insulation. Great stuff I have used this product for insulating basement walls, crawlspace walls, and other related projects. The two-inch thick product has R.10 and I have doubled up to 4 inches in certain spots to get R.20 total. This product is ideal for places where you do not stud out the area such as workshops, crawlspaces, etc. Also, this is available in the 2 foot by 4 foot size! So, there is no need to cut the panels down from a four-foot width panel to get through problem accessways such as those for crawl spaces. Lastly, I eagerly recommend this product to bring attic access panel R-values up. Just cut to fit your access plywood panel and glue the insulation to it. A dream product that works, is easily cut and worked, and does the job!! A perfect score from me. January 10, 2010
Rated 5.0 out of 5.0 by Effective Insulation I purchased sheets of this in R10 and installed double thicknesses on the wall inside the unheated garage attic to provide insulation for my master bedroom wall. The comfort level in this room was immediatly improved. Drafts and the feeling of cold damp air from our Colorado winter immediately subsided. This product coupled with blown in celulose insulation provided the most pleasant winter I've had in many years. Also--at age 50 this year, I did it myself without any help from my hubby! Home Depot is my craft store! May 29, 2010
Rated 5.0 out of 5.0 by Very easy to work with - excellent for both insulation and air sealing I cut this up into small rectangles and sealed around the top of my basement walls, using great stuff around the edges. It has really sealed the area up nice and tight. Now I'm going to use it against the concrete walls of the basement. very easy to cut. Very strong. July 12, 2012
Rated 5.0 out of 5.0 by Great with insulation We laid the foam beneath the wood under which we blew in insulation. Works great. Easy to use. March 3, 2013
Rated 5.0 out of 5.0 by great insulation Great product I put up in basement to protect pipes from polar vortex. Easy to use and notice an improvement in the warmth downstairs. Realatively easy to cut. March 4, 2014
Rated 5.0 out of 5.0 by excellent insulator We used this insulation board around our ac window unit. Fits nicely and cuts easily. Makes a big difference keeping the heat and humidity outside. July 8, 2014
