Here is my post from a year ago:

"I recently asked for help in finding an affordable (36†x 45†minimum, R= 0.8 or greater) hearth pad, aka hearth board. My dealer had tiled ones for $539 and up. He also said his cheapest was a black metal-covered one for $150.

After a lot of online searching, the cheapest one I could find was $208 plus $150 shipping, with a 2-3 week wait. Then my wife suggested I call a local Richmond Ace Hardware dealer (Pleasants, an old-line family-owned store). They had two sizes in stock, but both were too small and neither gave an “R†rating.

I took down the name of the manufacturer and called them (a Canadian company, Imperial Group). Seems as though they have a complete line of various sizes and three finishes, all very reasonably priced and all with an R rating of 1.08, sold with the “Imperial†label. They supply many stove dealers as well as Lowes, Ace Hardware, True Value, and Tractor Supply. I checked online and found a nearby Lowes with 4 in stock in the size I need. Because this is a seasonal item for Lowes, they were all clearance priced at $43 (instead of the normal $57).

The major breakthrough I had: when looking online, searches for “hearth pads†or “hearth boards†will bring up premium products with premium prices. The way to find budget-priced items is to search for “stove boardsâ€.

Oh, by the way, the Canadian company said they ship to my stove dealer as well. That means the product he was going to charge me $150 for, I bought on clearance at Lowe’s for $43!"

The reason I reposted this is that upon getting my stove board home, I noticed that printed on the insulating material on the back was "Micore". Apparently, the stove board is a sheet of Micore covered with thin black sheet metal on the top and sides. If you need Micore, check your Imperial Group dealer to verify that "Micore" is printed on the back. The boards are available in different dimensions and can be layered to increase the "r-value".
 
Dan.....what county is your cabin in? (I'm a Valley boy, Augusta County.)
 
It's in Mathias, WV, on the west side of North Mountain, in Hardy County. I'm just three miles into WV, north of Fulks Run, VA.
 
Thanks for posting this.

2 years ago, when I initially got my stove, my wife picked up a "stove board" from TSC. I didn't get around to installing the stove until this fall, and after reading up on the required clearances, I realized the cheap stove board was too small. My wife then went to a concrete and tile place and they sold her something they assured her would be adequate. However, it has recently been pointed out to me that my current hearth pad my not be to the stove's manufacturer's R-rating requirements. As a result, the simplest thing would be to put a couple layers of micore underneath the current pad. As for the cheap TSC stove board, it has since been used for various things, the current being a shield to protect my paint from firewood next to my house. After reading this informative post, I inspected the back of the board and do not find the words "micore" anywhere, but I admit there is some printing I'm unable to make out. The original packaging is long gone. So, I went to my local TSC and found the Imperial boards of which you speak. Unfortunately, the packaging does not indicate an R-rating anywhere, and the packaging is sealed so I cannot inspect the back of the board. Is it possible the stove board would not have the micore stamp on it, yet still be micore?

Assuming these Imperial stove boards I've found are, in fact, micore, should I remove the metal sheeting and layer them under my current pad, or leave them intact. I probably will use two sheets to ensure I exceed the minimum R-rating.
 
Well, I'd take a photo of the back of my stove board, but the stove is sitting on it! I looked at the back several times before noticing that it said "Micore". You are correct that the packaging doesn't give an "R" value, but when I measured the thickness of the board, it provided the correct "R" value for my stove (0.8 or greater...I don't remember what it was).

As to removing the metal sheathing, I didn't try so I don't know how difficult it would be. As I recall, the Micore was soft and spongy, so it might be better to leave the metal on. I don't know if the Micore would bend and break under its own weight. I ground the metal surface to roughen it, then glued ceramic tile to it. It isn't a stiff surface, so I don't stand on it for fear of cracking a tile...so far, so good.

Let us know what you end up doing and how it works.

P.S. Your TSC may let you open the cardboard package to examine the back of the board. My local Ace Hardware let me examine one, even though I didn't know to look for "Micore" at the time. It doesn't harm the board in any way, just opening the package neatly.
 
I wonder how many types of Micore boards there are. 160 and 300 is what I can find..

I am on a hunt now.
 
I figured I'd make everyone jealous. Kamco Supply in MA (elsewhere in NE too) carries Micore products. There is one in the next town over and they have tons of Micore 300 in stock. Drumroll.......$28 for a 4x8 sheet.

I'm thankful for this thread through because I will end up using black stoveboard for my wall protection. Cheaper and easier than attaching sheet metal to Micore and mounting that to the walls.
 
Thats not a bad price for Micore 300. If you can find it locally, its definitely cheaper than buying it online because they don't have to package the heck out of it to keep it from getting damaged in transit.
