I'm fastening my cement board to the floor over the Micore300. Has anyone heard of the screws compromising the integrity of the Micore's insulating value where the screws penetrate to the sub-floor? They are coated metal screws for cement board, but could they conduct enough heat down to the wood to cause a problem?
My instinct is the answer is NO, and there would not be enough heat down to the point of the screw to endanger the sub flooring. But metal is a great conductor of heat, and the screws will take whatever heat comes through the stone and mortar I suppose. I could NOT screw the board down directly under the stove footprint as an option, but I'd weigh that with the need to have the board tidy and snug for my tile work.
Thanks.
