An example I often use for the purpose of these discussions is Mirage. I've ben to their facility in Quebec and it's impressive as hell. they're people are what really impressed me the most. Everybody there is just a font of knowledge. Now they specifically tell people to NOT acclimate other than for temp. Why? Because you'll ruin the wood if you do it in a place unsuited for wood. That's really what it gets down to...the environment, not the product. Unless you're in some freakish place like Arizona or New Mexico, you aren't going to be drying the wood out any more by acclimating it. If you're in a place that's reading 12 -14 %, guess what, it's not a suitable environment for wide solid wood. Sorry, them's the breaks. So what to do? Get the wood wet? No. Dry the dang house out. The bottom line on acclimation can be seen in the dual reccommendations most everyone copies and pastes from NWFA. On the one hand, they say to "acclimate" by dropping the material off a couple days before you install. (aka, Jump through a stupid hoop) and then immediately after that they go on to describe the environmental requirements. They are between such and such degrees and such and such RH (45-55%, i seem to recall) well guess what. If you refer to the US Forestry Service matrix showing MC at various temp/RH combos, what they prescribe just happens to land right around 8%. 8% is what the wood (all wood) is when it shows up in the box. So, in short, they require you to have an 8% environment and also to acclimate the 8% wood to the aforementioned 8% environment. It's a joke.
