¿Un techo de metal necesita una barrera de vapor??

A metal ceiling might need a vapor barrier depending on where it’s being installed and the possibility of moisture problems. Vapor barriers stop moisture from getting through to the insulation, which helps to decrease condensation and the growth of mold. Things to think about include where the ceiling is going, the building codes in the area, and if there’s a lot of humidity or moisture. It’s a good idea to talk to experts who can give advice that’s specific to the situation.
