Hearth

I plan on building my hearth over this weekend and looking for a little advice.

I am going to use 3 layers of 1/2" Duroc on top of the 1" air space on the floor. Can I use wood 2x4 and be safe or should I go ahed with metal studs like I am using On the wall. I was told metal studs are overkill, but I want to be more than safe.

We need to know more about the stove requirements that are trying to be solved. What are the hearth and wall clearance requirements?

I am installing a Buck 27000 B. With a 1" air gap and non combustible materials on the walls, I can put my stove about 6" from the back wall and 8" from the sides.
The stove has 6" legs and I was told I needed to meet an R value of 2. I am planning on using 3 layers of 1/2" Duroc with 28 guage metal between layers and ceramic on top. The air gap on the floor will offer at least R 1.
The hearth will be 52" square for the stove to sit on.

There isn't much $ difference between the wood or metal studs, I just already have wood here and could use it if it is safe. Definitely using metal studs on the wall.

What are the required clearances for the stove? You usually cant get down below 12 with shielding and where are you talking about using wood in the hearth?

The miminimum to wall with 1" air space and non combustible is 5 3/4" on back and 8" on sides by using 24 guage metal. I was thinking of using Duroc and metal on the sides and going out 6-7" from back wall with the stove.

I am considering using wood studs on the floor of the hearth for support and topping that with 3 layers of 1/2" Duroc with 24 guage in between layers and topping it off with ceramic tile.
