Studio - Window, Floors and Doors
What used to be just a layer of glass to the outside was
turned into a closet.† Before any of the
pictures above were taken, the windows themselves were sealed off.
All told, from the outside in, the windows
were covered with:
- A layer of soundboard, painted white, was carefully fitted behind the
windows.† This is what shows on the outside now.
- 2 more layers of brown sound-board were added to the windows to
"even-out" the spacing (as they were "pull up" windows, there was an extra
2 inches to fill in for the top portion of each window. All gaps were
- A final full layer of brown soundboard fills in each window area
(with more caulk).
- A 2x2 frame was then made on the inside of each window area.
This was filled with insulation.
- 1/2" plywood then brought the windows areas flush with the columns between
them. More caulk.
- A sheet of brown sound board then was used on all interior surfaces
of the closet.
- An extra sheet of grey soundboard was added to the walls of the
- The interior of the closet was finished with 1/2" drywall.
So, all told, there are nine layers between the window glass
and the back wall of the closet.† Then,
if you count to the inside of the room, there is an additional layer of 1/2"
drywall, insulation, another layer of 1/2" drywall, and a layer
of the grey sound board.† Below
you can see a (current) photo of the solid-core door, hardware and
molding that I added to finish the closet.
Studio - Floor and Door
Wait!† Thatís not it.† Even though I already soundproofed
the attic, gabled ceiling, ceiling, and walls of the room, there were two more
crucial sound-proofing areas to consider: the floor and the door.
The thing with the floor is that itís important to
mechanically decouple it as much as possible.†
This means that the new floor should (a) not touch the walls, and (b) be
"floating" on a layer of some soft material.†
After pricing various alternatives, I finally settled on these snap together
1/2" rubber sheets.
On top of these sheets I laid an additional two layers of
3/4" plywood Ö very heavy Ö in such a manner as to ensure that there were no
overlapping seams, and that the plywood did not touch the walls.
The two layers of plywood were then screwed
together, taking care to not allow the screws to touch the original floor.
Thus I ended up creating a "floating"
On top of the plywood I added new padding and brought the
original carpet back in.
I also tossed the old interior door, and added a new 1 3/4"
solid core door to the room.†Because of the new raised floor,
it has to swing the other way (from the outside in), and I added
weather stripping so that when it is closed it is airtight.
