What is the best way to inexpensively vapor barrier a wall?
Hi,
couple questions -
what is the best way to vapor barrier a wall with non toxic materials to prevent mold and moisture
and
how do you make sure that the furniture and bed in a place does not absorb a lot of mold?
A vapor barrier or vapor retarder is any material that slows or stops the migration of moisture, so there are some options. But there are a lot of variables to consider when choosing the best way to manage water vapor in walls, so first start with understanding, and I suggest this page -
Understanding the difference between vapor barriers and air barriers
We would need a bit more information to answer your question accurately, so first let us know where you are building or your climate zone.
Also let us know what the wall currently is, and why you're asking. Is there a mold issue? Is it a basement or an above grade wall? How old is the home? And what is the current wall assembly, is it a stud frame wall with batt insulation and any membranes? I'm assuming it has no vapor barrier if you're asking, so fill us in a bit with what you've got and what you want to achieve.
