budget. With this economy people are always looking for economical ways to
soundproof their home's.
These days many homes have home theaters or entertainment rooms. When
building a home theater, you want to make it as soundproof as possible so
that you can watch a movie at 2 AM and not bother the other occupants of the
house.
If you are soundproofing from scratch, there are many common building
material that can be used in place of more costly professional soundproofing
agents. For example, you could use rolled roofing as a sound barrier in place
of many vinyl barriers. The rolled roofing will not be nearly as effective as
mass loaded vinyl, but it is better thank doing nothing to soundproof.
In todays economy, even the professional soundproofing agents are quite
affordable. Mass Loaded Vinyl (MLV for short) used to cost as much as $10 per
sq ft, but these days, that same loaded vinyl costs around $1.10 per sq ft or
less. That would actually be less costly than the rolled roofing and would do
a much better job on both walls and ceilings.
Now this being said, high grade drywall itself is a decent soundproofer and
can he had at any hardware store or home improvement center. The combination
of mass loaded vinyl and drywall make for an excellent sound barrier wall
assembly, that would keep costs to a minimum.
If you are in to process of building and soundproofing a Home Studio or a
Home theater there are many economical things that can be done to soundproof
the room as well as to add very effective sound conditioning materials that
will reduce the echo in that space.
If you are willing to do the ultimate soundproofing job for your Home
theater or Studio, then you would be looking at floating your walls as well
as your ceiling using the RSIC-1 sound clips and furring channel system.
To properly float the walls and ceiling you will need to remove all existing
drywall in the room. You need to be working from the bare studs and joists.
The first step would be to add rock wool to the joist and stud cavities.
rock wool is a very effective sound batt insulation that would be placed in
the cavities. In the ceiling it is best to place the rock wool up against the
bottom of the sub floor above. It needs to contact the entire bottom of the
sub floor. Once the rock wool is installed in the joist cavities, you would
fill the rest of the cavity with regular fiberglass insulation.
Now we come to a crossroads. It would be very helpful to add a product to
both the walls and the ceiling called Mass Loaded Vinyl. MLV is a high grade
vinyl material that is impregnated with barium salts and silica which gives
it mass. The MLV would be stapled to the ends of the joists and studs to form
a soundproof membrane. You will need to caulk all of the seams of the MLV as
well as around the perimeter. Note, it would be best to over lap seams
wherever possible and then to caulk the peremeter of the vinyl membrane.
The next step would be to attach the sound clips to the joist assembly. The
RSIC-1 clips would be installed every 4 sq ft plus there would be clips at
the edges as well. Once the clips are installed as per the instructions, you
would then fit them with a metal furring channel. This channel should be a 25
gauge steel 7/8" furring channel that you will get from a local drywall
supply house. These channels will compress and fit tightly into the sound
clip.
Now that the sound clips and channels are installed, you would then screw up
a layer of 5/8" drywall. The screws must hit the center of the metal furring
channels.
As you install the drywall, make sure that you leave a small gap around the
perimeter of the drywall where the drywall ceiling does not contact the
adjoining walls. This gap will be filled in using a foam backer rod and also
acoustical caulk. Once the new ceiling is sealed around the edges, you would
simply tape mud and paint ot texture the new drywall ceiling.
Now that you ceiling is complete, you would use the same procedure to float
the walls.
