This might be a dumb question, but I see a ton of how-to videos that use wooden edges on hearth pads. My question is, when the pad requirements say “eight inches to sides of stove,” I’m assuming that is for a 100% non-combustible pad, which means all these pads I see being made with wooden edges won’t be to code unless the wood is at least as far away as the stove’s required distance to combustible walls. Am I interpreting that incorrectly? Also, if the stove specs say .47 r-value (jotul 602 v2, for instance) how do I know what materials will be sufficient? On a tiled floor installed over wooden subfloor, would a layer of 1/2” cement board covered in 1/2” tile be sufficient? I was originally going to build it with an oak surround but now I’m thinking it might need to be angle iron or aluminum (ugly). Any advice? I don’t want to just buy one premade because the required footprint for the stove is 43 1/2” long by 28 1/2” wide and all the premade ones that meet the length requirements are way too wide. Thanks!
