Historically, though, wood structures have been built (intentionally or not) such that the wood is dried by the heat escaping from within. Modern wood structures are paradoxically designed for energy efficiency, which is in conflict with the above. You can't have an efficient building where the interior heat escapes constantly. Since we're still in the early decades of this paradox, modern wood buildings tend to be designed to be water-tight, and when that inevitably fails the structure is destroyed.
- vlehto 11y agoOld adage of construction, if you think "but how could this ever get wet?" you're fucked. Everything will get wet at some point, so everything has to be self drying. The plastic film stuff has been tested pretty well for current structures. But as the insulation thickness increases there might not be big enough pressure gradient across the structure. Concrete does not get a pass though. Here in Finland we have had bit thicker insulation for a while. Even if you don't get wood rotting, you can get mold. That ruins indoor air quality.
