Air tightness is fine, because when it's done anywhere close to the right way it comes with filtered heat recovery ventilation.
You're right about building materials, but that's true regardless of the air tightness: engineered woods, all kind of glues, all kind of foams, paints, sealants, hard to tell how nasty they are but they for sure aren't beneficial.
- amluto 2y ago> all kind of glues Glues are getting better over time. Slightly nasty polyurethanes [0] and quite nasty solvent- and bitumen-based products are gradually being replaced with STPE, and STPE seems to be considered quite safe. It doesn’t even have a prop 65 warning! [0] Polyurethane may well be harmless when fully cured, but the uncured isocyanates are most definitely nasty. Fortunately, they’re so reactive that they will aggressively react with water (even just moisture in the air) or almost any alcohol and produce much safer products.
