- I've been considering blown insulation for the old (55 year) portion of
- the house Three separate salesmen all told me that the average paint
- buildup on walls old enough to have no insulation is quite adequate as a
- vapor barrier in metropolitan Wash DC. Glidden reportedly sells a paint
- (Insul aid) specifically formulated for impermeabilty to moisture. This
- paint would likely be the most cost effective way to add a measure of
- vapor resistance to your walls.
