ASC-WallDamp is a double
sided, self adhesive sheet of material and it's two step application
is simple and quick. Just remove the release paper and place WallDamp
between every joint, every connection in your wall. The pressure
sensitive adhesive of WallDamp glues the wall together and that
improves it's overall structural integrity but more important is
the polymer compound of the WallDamp sheet itself. WallDamp located
between the wallboard and the framing members of the wall improves
the soundproofing in three ways.

It is helpful to learn more about these three types
of sounds. They can be easily stimulated in any wall. Try a few
experiments. Have someone stand on the other side of a wall and
scratch the surface, lightly with a pin. The scratching noise you
hear is due to the conduction of sound through the structure of
the wall. The sound starts in one sheet of wallboard, it passes
into one side of the stud, through the stud, out the other side
of the stud into the wallboard on your side of the wall. WallDamp
placed between the wallboard and the framing greatly reduce the
conduction of sound through the wall.
Here's another experiment. Make your fist and stick
the middle knuckle out a bit. Now, walk slowly along a wall knocking
on it and listen to the sounds. Where the sound seems dull, is where
a stud is located. The sound will seem louder and more hollow at
positions halfway between the studs where the wallboard is unsupported
and freely vibrates. When WallDamp is sandwiched between the studs
and the wallboard the hollow twang of plate vibration is damped
out and the wall begins to sound more like an old, lath and plaster
wall.
Finally the last experiment. Make your fist tight
and notice the hard thickness at the heel of your fist. Walk along
the wall and thump middle of a stud wall, about half way up with
the tight heel of your fist. That low boom you hear is due to structural
vibration of the whole wall. Wall shudder is caused when the upper
and lower edge of the wall is pinned at the plates. The unsupported
mid section of the wall is easily stimulated into a low frequency
shudder. WallDamp sandwiched between the wallboard and framing damps
out this whole wall motion.
ASC-WallDamp improves the soundproofing of any wall
in three distinct ways with one simple application. Adding WallDamp
strips between the wallboard and the framing glues the wallboard
to the framing and then damps out conductive, plate and structural
borne sound and vibration. |
