Could this Flexi-brick be used for on the wall behind my woodstove? It says its class A building material that can with stand temps up to 212 degrees. What has me puzzled is that it can be cut with a knife or scissors. Also i have read that i should use metal studs for my 1" air gap but where can i get metal studs from?
Flexi brick.

No, that isn't nearly a high enough temperature rating. You need some like durock sheathed in brick veneer, not that stuff.
And the metal studs can be found at most local home improvement stores like Lowes and Home Cheapo.

Flexibrick is mostly silicone, which takes fairly high temps....but as Corie says not hot enough for wall protection, which in theory can get much hotter (but in actual installs usually does not).
So unless it is listed as non-combustible and non-fire and smoke spreading, and for that use.....
It would seem possible for a company to get a silicone product tested and listed for such use (example - 500+ degree silicone), but probably not worth the testing and R&D;cost.

As to the air gap. most folks use strips of the Durock.
If you want steel stud (too wide, in my opinion) or hat channels(would probably do), get them at a drywall supply house, some masonry yards or possibly even Home Depot.

I kinda figured it was silicone based. My parents have a wall made out of what i thought was this. Only there wall is actually 1/4 or 1/2 in real brick. I was hopeing it was the same stuff. I guess my hearth search ventures on.

I've purchased these 1/2 bricks at certain masonry yards - actually they are like "1/8" bricks.
Funny thing is, here we are saying that 200 is too hot, while even most ceramic tile and the cements used for them are not rated for that! Strange....
The real answer to this question is to ask the manufacturer of the material. I have seen UL approved hearth boards that have combustible materials in them - specifically wood and paper (sheet rock paper), etc...... let us know what you find out if you do contact them!
