vapour between drywall

muscle's picture

Currently renovating a house built in 1952. (located in Ontario, Canada).

Removed all drywall on out side walls in insulate and wire.

Wanted to save money by leaving drywall and Insulation on ceiling!

-Can I put poly over old drywall and then just re-drywall over?

I will use acoustic seal also. The current product is two layers of drywall aprox 2ft x I guess 8ft

There's probably already so much oil paint on the ceiling that you don't need an added vapor barrier.

Of all the preposterous assumptions of humanity over humanity, nothing exceeds most of the criticisms made on the habits of the poor by the well-housed, well-warmed, and well-fed.  --Herman Melville

There's probably many coats of lead based oil paint on the lath board.

Hope he used some of the methods of containment outlined in the
