I'm about to take possession of a condo and one thing I plan on doing
is laying down hardwood. Condo policy is that there needs to be a sound
insulation barrier. I'm trying to figure out whether I need a plywood
barrier or do I go boards onto the cork directly. THis is what they did
in my parents' unit for instance, and I think that the floor planks were
simply glued to a cork underpad. The other way would be to put cork
down, then plywood, then nail the boards to the plywood.
Question is, what are the advantages/disadvantages of each approach? If
not using the plywood, and just gluing a floor down was hands down
cheapest, then everyone would be doing that, but some people nail a
hardwood floor to plywood.
THanx in advance
