Noticed that part of the sill had rotted away, the problem is that I can only find the right dimensions in untreated timber, 100x100mm. Treated timber is available, so the question is, does the risk still remain in modern treated timber like in what was installed in houses from the 60s to 80s?
Well, that's positive because a friend of mine had treated wood in the joists, and there was a water leak in his kitchen, and then it started to smell from the cuprinol, but you should probably check with a carpenter because they must know about it. When we've replaced parts of the sill, it's gone fine with untreated wood. Good luck. =)
According to hearsay, in the past, impregnated wood was used for the sill in houses with crawl space foundations so that it would withstand higher humidity without rotting. The downside being that it gives off quite a smell in this rather enclosed environment.
Not infrequently in modular houses from the 1950s to the 1970s, the sill was impregnated, the subfloor panel was made of asbestos cement, and the support plank for the subfloor panel was impregnated.
Today, it is considered a bigger problem if there is such high humidity in the crawl space that untreated wood risks starting to rot, that it is more important to solve that problem in the long term.
Go for untreated wood, but don't forget to place sill paper underneath!
