    I am a building contractor in my other job. We use a few different types of MR drywall (moisture resistant). I do not see it working out well at all in a sugarhouse. Drywall does not hold up well in damp environments especially an unheated building like a sugarhouse. Also washing and cleaning walls would not work well. If I was building a new sugarhouse I would use FRP sheets anywhere that would be exposed to steam, water or potential mold. I have pine walls with poly and they are showing water stains and are hard to clean and definitely looks far from new. The FRP cleans right up.

    I also work in the construction industry. I'm a commercial and residential construction cost estimator. I second the FRP panel! there is also another product that is called "trusscore" that I would recommend. they are easy to install and come in long lengths and can be used without a plywood backer. the FRP is a good product also however!

    Our sugar house is timber framed in hemlock and walls are hemlock tongue and groove. Rough sawn side out, milled side facing the interior. Nothing on it at all and after 8 years still looks like new. I think any stain or finish may be a problem with the steam; with plain wood the steam seems to keep it all looking new and fresh. I hose it all down at the end of the season also.

    Sorry morningstarfarm, I'm unclear on your responce. You've had what on your walls for five years? Bluerock or FRP? Ted

    We went with FRP on the walls and ceiling and are really happy with it and so was the State inspector. We also used solid vinyl firing strips and trim so everything was washable. All screws and fasteners used are stainless steel.

    White steel liner panel is good too. We have a few areas done with it, and it cleans up easy. The FRP is a good choice also, I just can't whole heartedly​ endorse it because I HATE installing it. The MR might be ok if you use the right paint

    Bluboard or green board moisture resistant sheetrock will grow mold...It it resist moisture....I'm a drywall contractor of 15 years....If you use a gypsum product go with the E2xp from national gypsum or a comparable, it's an exterior sheathing board wrapped with fiberglass, I'd you paint use an epoxy grade Industrial coating.....Your better off with frp it will never cause an issue

    "Au-naturel" , it can't be bad to use untreated timber. If it was then we couldnt make maple syrup from free ranging maple trees. I'm with Jonh on this one and someday my dream shack will have that same look and style.
