Vapor Barrier for blow in fiberglass in an attic.
We currently have an asbestos abatement contractor removing vermiculite from the attics of two 1930s era houses. Which will leave them without any insulation in the ceilings.
I plan to go in after they are done and blow in fiberglass. There was no vapor barrier in the original construction. The encapsulent the abatement contractor is applying may be impermeable enough to function as a vapor barrier. I have written the encapsulent manufacturer for thier advice to find out.
But, assuming the encapsulent isn't a sufficient vapor barrier, does anyone have suggestions on what we could use that isn't going to be too difficult to install in an enclosed attic?
