I'm looking to put a gas fire pit on my wood deck. The plan is to frame out the walls, cover with duroc, put stone veneer on the outside, cap with 2" sandstone slab, fill the middle with gravel, install a gas fire ring, then top with decorative recycled glass. Does this sound ok? With all of the heat being generated above the actual fire pit I'm thinking the heat transfer will dissipate before it gets to the wood.
gas burns at a fairly low temp so it sounds ok to me but i'd add a layer of mineral wool insulation to be more assured,,, you might ck w/your ins co or local fire dept,,, heat rises but will also transfer thru solids fairly easily
