I left some of my scrap board outside for the winter with many pounds of weight on it. It seemed to survive fairly well. I know what you mean though - when I was leveling my hearth bricks with wet fire clay, it was tearing it up pretty easy. With that said - I try very hard to keep any rain off the product. I have a huge vent cap and I place a piece of tile over the vent when I'm not using it.

Which refractory board are you using? The only problem like this we've heard reported is Ken's problem with Kaowool:

Both the Cal-sil board and the stuff I used (H-W insbloc19) will stand up to occasional wetness.
