We're going to be building again soon, and I am totally spooked by the engineered-wood floor trusses. Are they stable? Do they work? Do they squeak?
Engineered wood is great stuff, as long as you are absolutely, positively sure it will never be in a wet location. Once it is in a wet location, all bets are off.
So if you are doing interior work and you have a fair amount of confidence that the roof won’t have a chronic leak and you will not have any long-term plumbing problems, it is great stuff. Solid and stable and better than lumber, IMHO. But I had a 12x24 glue-lam beam that wound up under a small leak where I work, and the entire thing delaminated over time. By the time we detected the leak because of the deformation, it was too late, and the entire beam had to be replaced, which was a tricky process, to say the least.
