Studio - Attic and Ceiling
The work actually started in the attic. The attic consisted of insulation lying on
the drywall that was the ceiling of the studio, and then an air space, then the
plywood that made up the roof.† So all told, in the attic, the only thing stopping
the sound was 1/2" drywall, a little insulation, and 3/8" plywood.
Itís a shame that I didnít take any "before" pictures of the
attic. However, hereís some "after" pictures.
I glued-and-screwed 1/2" plywood onto the floor of the
attic above the band room, insulated the roof and walls, and then
screwed 3/8" plywood to them.† I also used 1/2" drywall
in some places.†All cracks were sealed with flexible silicone caulk.
The air-co guys
installed the blower unit and ran the piping to the ducts in the various rooms.
Once again, itís hard to explain how much hard work went into the attic
above the studio.† All the materials had to be cut down to 2 ft sections
that would fit thru the portal to the attic, and hauled up from the ground
floor the second floor, then hauled up a ladder to the attic, and maneuvered
around in the tight spaces there. In the end there were 8 full sheets of 1/2"
plywood, 6 sheets of 3/8",† 2 sheets of 1/2" drywall and a
whole pallet of insulation cut down and man handled in that way.
It was nearing summer and the attic would often be 105 degrees or hotter,
and you could only work for a couple of hours before nearly passing out.† The
glue and caulk was a mess, there was no room to swing a hammer, and you would
get little holes in your head from bumping up against the roof nails. I was
itchy for a several weeks from the loose insulation and breathing the
fiberglass and dust was injurious to say the least.
When it was all done I had added 2 more layers of plywood
and a layer of insulation, and almost a 1000lbs of mass to the attic. Plus I
had sealed off all of the air leaks that would let sound out, so I think the
work significantly helped the sound-proofness of the final studio.
Studio - Gabled Roof and Window Box
Before starting on the studio, I yanked the carpet and
padding and threw them out the front window.†I saved the carpet,
but threw away the padding.
As I mentioned, there was this odd shaped gabled roof at the
front of the room. Above the window was, the best way to describe it, a hollow
box.† I cut into the walls of the hollow box and stuffed it full of insulation.
Also hard to explain is the area behind the attic wall shown in the photo above.
It was another empty box which was stuffed full of insulation before this picture
was taken.† Finally, before this picture was taken, we got a "drywall lift" and
added a layer of 1/2" drywall and a layer of 1/2" sound board to all
interior surfaces.† Every time I'd add a layer of drywall or soundboard, all
the gaps were sealed with silicone caulk.
I then built a "drop ceiling" into the gabled roof.
Below you can see one of the two 4x4s
and the 2x4 rafters for this new ceiling.
Note the air conditioning duct tubing that comes out of the
After this photo was taken, I topped the rafters with 3/8"
plywood and stuffed the whole space full of insulation.
More insulation was then placed between the
rafters and 1/2" drywall was put into place for the ceiling. Later, in the
finishing of the room, two more layers of 1/2" sound board were
Note that there were two kinds of soundboard used in the
studio, the brown stuff, shown above is very light and easy
to work with, but doesnít really do that much for sound-reenforcement.†
The grey stuff, shown in other photos below, is very heavy and provides
much better sound-insulation characteristics.
