Rated 5 out of 5Â by RJ0369 Garage Door insulation
I used this product as a garage door insulation. Installed it on each door panel cut to fit with the foil side facing outward. Must install it on some type of standoff, I used 1 inch pink foam board strips I cut and glued to the door panels, then put this over them leaving an air gap between the foil side of the R-Max panel and the door panel. What a huge difference this makes in the temps inside the garage. My garage door faces south-southeast so it gets very hot and makes the garage hot too. Not anymore. Great product and easy to work with. I added a bubble radiant barrier to the inside as well to keep heat in in the winter too.

Rated 1 out of 5Â by SmallManufacturer Two years later, quality control still terrible
It's been about 2 years since HomeDepot switched from Dow Super Tuff-R to R-Matte Plus-3. My hope was that perhaps the size and frequency of voids would reduce as more customer feedback made it clear there was a quality control problem. I've used about 800 sheets of this stuff now and sadly, there is no improvement. Some batches are almost good with only small voids and little loose facing. Many batches are terrible with dollar-bill sized voids in the foam. One batch had 1/4" thickness variation from one edge to the other.

I bought this product to use in my garage. It's made with expanded foam pellets and when you cut the
sheet the pellets come apart and you can't make a straight cut, they break apart and you can't get a nice edge. Also, the pellets that fall, cling to everything, it makes for a messy clean up. DO NOT BUY THIS PRODUCT !!!!!!!!!

Rated 1 out of 5Â by Rich Extremely poor product!
Home Depot replaced the Dow "Tuff-R" polyiso board with this new Thermax product. The Dow board is far superior to the Thermax board and carries an R value of 6.5 per inch as opposed to Thermax's 5.9 per inch. Since they're both priced the same, that's an effective 10% price increase for H-D for the equivalent R value. The Thermax board also delaminates during cutting and sends hundreds of "floaters"(small beads of foam) in the air when it's cut. Very annoying!!(and possibly a health hazard?). I've probably used 300 sheets of Dow Tuff-R over the years but I won't be buying the Thermax board. I've discovered that Menard's carries 3/4", 1" and 1 1/2" polyiso board with an R value of 6.5 per inch at a 10% lower price than the Thermax board. That represents a 20% cost savings for the same R value! Worth the trip to O'Fallon for large purchases. Whoever the HD merchandise genious was who thought this was a good move ought to be questioned at length on this one!

Rated 1 out of 5Â by SmallManufacturer Miserable Quality Control
For some reason, Home Depot and the other big box store both switched from Dow Super Tuff R to this product. I've used Super Tuff R for 5 years (probably 600+ sheets per year) and found it to be of superior quality.
After the switch to this new product, I spent 15 minutes sorting through the stack of 30+ sheets of this new product (R Matte Plus 3) and could only find 6 sheets that didn't have 10% or more the foil facing loose or peeling off the shiny side. In cut outs, pea-sized voids in the foam were common and I twice ran into silver dollar-sized voids where the foam was completely missing.
Maybe the average person wouldn't notice the flaws, but I do not believe that an average sample of the sheets available at either of my local Home Depot stores would pass independent testing to meet the rated R value with so many voids and flaws.
I love my local HD staff, see them almost daily, but this new product (which probably is cheaper for HD, but not for me) is a deal breaker.
