This Energy Star qualified R-Matte Plus-3/Thermasheath-3 provides R13.1 with dimensions of 2 in. x 4 ft. x 8 ft. This product is designed for exterior and interior, non-structural uses.
  • Rmax polyiso sheathing offers the greatest R-value per inch currently available in a rigid foam board
  • R-Matte plus-3/Thermasheath-3 is applied to the exterior or interior face of wood or metal studs to cover all studs, sills, plates and header constructions, thereby providing insulation over areas not normally covered by insulation products
  • Superior resistance to moisture and vapor in above grade applications
  • Polyiso rigid foam board offers superior fire protection properties compared to any other rigid foam board insulation
  • ENERGY STAR qualified to meet or exceed federal guidelines for energy efficiency for year-round energy and money savings

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.

Can this be installed directly in contact with a concrete foundation, and can it be in contact with the earth

Asked by: Jrc
The answer is yes to both questions. When installing to the concrete walls you must use large plastic pins along with special glue for foam board to make sure the board holds to the wall and sets up.

Can it be used under a new metal roof? If so, please provide recommendations for the installation.
Asked by: JMW
Yes, but you need to provide at least a 1" airspace between the insulation and the roofing to create a thermal draft to prevent moisture buildup.

Rmax Thermasheath-3 2 in. x 4 ft. x 8 ft. R-13.1 Polyisocyanurate Rigid Foam Insulation Board is rated 4.7 out of 5 by 23.

A few of the sheets (approx 10) were damaged, but I was able to complete the job with enough leftover to insulate a 16x12x13 shed. Dampness is no longer a problem in crawl space(70 inch) any longer. More care should be used in the storage , handling , and delivery of these rather delicate sheets.

I am finishing my basement and was researching the best option for R-Value, water proof and ease of use. The Rmax Thermasheath did the trick. It was easy to install, has a higher R-value than other rigid foam insulation and could be put directly on basement walls. After installing on all of the walls and sealing with the recommended tape, our basement temperature jumped by 5-6 degrees from 54-55 up to 60-61 degrees. One note, the insulation is 2" thick so you will need an extra long utility knife blade to cut. Using a saw works too but makes a lot of extra mess.

Added it to an old 2x4 exterior wall being refinished inside to more than double the insulation value. Marked where my electrical lines were then used construction glue and 3 1/4" screws to hold the sheetrock and insulation to the studs. Really helped lower noise coming from outside too. Used a battery powered jig saw to cut smooth edges which created quite a bit of air-born particulate, so definitely use a dust mask & goggles if you have them.

I couldn't help but notice everyone trying to cut this with all the different tools. I wanted to point out that an electric hot-wire cutter is the tool of choice for cutting these boards. You want have all that fly away Styrofoam balls everywhere when you use the right tool for the job. Easy to use and very simple. I discovered these boards decades ago when they were only a couple dollars for a 2" 4'x8' and used them for my own insulating. I don't know why the price is so high other than they can get by with it. The 4" 4'x8' were only a dollar more than the 2" thick boards. It's a shame they gauge the customers like they do but then again, that was a mom & pop store that I bought them from before the larger corporations closed them down. Still, it is a great product and would use again. Get the hot wire cutter and save yourself the hassle. It uses heat to cut with which melts right through without any fly away styrofoam.

The R-value plus the air space between the insulation and the new sheathing has drastically improved our comfort level. Easy to work with and fairly square and true. Would be 5 star, if the price point was reduced by 20%.
