My
clothes dryer makes a lot of noise. Not long ago, I decided to do a little
laundry room soundproofing to quiet things down a bit. I drilled several holes
in the side edges of the hollow-core door to the laundry room. I then got some
spray foam insulation from the hardware store and sprayed it into the holes to
fill the inner door cavity. A half hour later, the door self-destructed and
oozed foam from every corner. Needless to say, I’ve installed a new
solid-core door.
