Mar 5, 2014 at 7:07 | comment | added | Keith Hoffman | Sorry about all the criticisms. Not trying to be a jerk. But ... you only want one vapor barrier. So an 'extra' vapor barrier is probably a bad idea. | |
Mar 5, 2014 at 7:01 | comment | added | Keith Hoffman | Because we don't know where the air barrier plane is in his house, I'd be reluctant to put an air grille into the wall space. The wall could connect to a furnace room with exhaust byproducts, it could connect to an unconditioned basement or crawl space vertically (another source of moisture). it could connect to exterior air, it could even allow insects in. Yes, in his drawing it looks like it is an interior partition wall but I'd want to know more. | |
Mar 5, 2014 at 6:59 | comment | added | Keith Hoffman | But I think your physics comment on condensation is flawed. In most older homes, the drywall and the polyethylene vapor barrier behind it are the only air barriers. Inside the exterior walls (and we don't know how this interior wall is tied to the exterior), you can have plenty of air moving. So the cold pipe would continuously pull humidity from warm passing air. | |
