After poking aroudn my house's basement, I found that I have
cantileveled floors(the floors over hang the foundation by almost 2 ft
on one side). The problem I found was that the underside of the house
is unsealed, although very insulationed, which allows for air movement
into the house where the floor registers penetrate the floor. (tiny
air gaps around the duct work and the subfloor) I saw on tv one day,
someone cutting holes for registers and paint a 'goop' on the subfloor
and an inch or two into the register. A comment was made it seals the
register to the floor agains drafts.
What is this? Can anyone tell me a product name, and any tips on how
to effectivly use it?
