New member here but long time reader. After extreme frustration on finding solid information on building a hearth & wall protection for my Alaska Kodiak 100,000 btu nut coal stove I came up with this idea. The construction is steel studs, two 1/2" layers of hardibacker screwed to the steel studs with fire caulk on joints, topped with ceramic grouted tile. The size is overkill, the actual floor protection im not so sure about. Please tell me what you think. Also please check my piping, i just did a barometric damper with two 90 elbows, i feel like im missing something. I also did a little science experiment because there seems to be alot of debate about hardibacker vs cement board, i put a torch directly on the hardibacker for 35 minutes, im confident that it will never catch on fire but not so sure about the heat that radiates through it. Its built now so maybe this is late but i want to make sure im not doing something really stupid here before i fire it up.
