And how do you keep the wood from being exposed to moisture without petroleum derivatives? Like technically it is possible but to build enough homes to that standard for even 1/1000 of the population is unreasonable
The house I’m sitting in right now is made out of bricks, with the roof being a untreated wood frame covered in ceramic shingles. No hydrocarbons involved (except for the insulation but that came a good sixty years after initial construction). There are other construction methods besides the American “just wrap it all in vinyl” approach that aren’t necessarily more expensive, such as covering the outside insulation layer with clay/mortar.
The problem isn’t air moisture, at 60 % air RH wood is like 10 % humid and won’t rot. What causes wood to rot is pooling water, something that’s easily avoided by decent house building.
