Hi everyone, I'm living in a house that I've been building for the last year and a half. My next project will be a hearth pad and wood stove. the stove will be a Hearthstone Heritage. The online manual says I need an R-value of 1.2 for the pad. I was going to try and keep the pad as close to the height of the yet uninstalled floor. The floor will be 1/2" floating floor. If I go with wonderboard (.40 R-value per 1/2") and natural slate I would have close to a 2" pad. The manual gives 1/8" horizontal still air .92 and mineral wool insulation 3.12, but I can't get my head around how I would incorpoate these into the pads consruction. Ideas? Also, I called for a price on this stove and he quoted me the MSR price as set by Hearthstone. I asked if this was negotional and he said that it wasn't less $100 if they don't have to deliver it. I'm 55 miles away. Is this the norm? I've rarely seen an industry that wouldn't dicker a little but demand would dictate I suppose. Thanks, Dan.
