i have a detached garage. it has 2x4 walls, and i insulated with r-15. i plan on heating this in the future. my question-- do i need to put up a vapor barrier? menards salesman says he wouldn't, this way the walls can breath. | |
Answers:
From: horsegal
houses have vapor barrier. why wouldn't they want the walls of your house to breath?
cars can create moisture, but if you are heating it, i kind of doubt that it is for the comfort of a car.
rain is moisture. that would be good to keep out.
i do not have an experienced answer for you. i sleep in an uninsulated horse trailer. during the night the moisture from my breath gathers on the ceiling and can cause rust ( and a wet head when i sit up. ) insulation alone will stop that problem.
keeping a window open is not enough air flow to stop this.
vapor barriers are meant to stop rain and mold from forming. (to my knowledge)
From: ISULATION PROFESSIONAL OF S.C.
as long as the wall material is un faced ( no paper ) and the exterior walls have no protective barrier on them putting poly on the interior wall poses no problem.
