A HOW TO GUIDE
FOR FABRICATING FABRIC COVERED ACOUSTIC ABSORBER PANELS
This "how to" is an attempt to
provide ideas for a cost effective acoustic treatment for project studios and
smaller music rooms. This type of panel can also be used in choir rooms in
churches. These panels can be assembled rather quickly without
PREP: The most difficult part of
the whole project is
getting the fiberglass batting. Some local building supply companies can order
the Owens Corning 703 panels. It is difficult to describe to a clerk since
it is fiberglass, but is it not traditional expanded batting type
insulation. Here is a link to the manufacturer's cut
The example in the pictures is
the model 703 fiberglass boards. The 703 model is 1" and works well for
smaller rooms. It is also made 1.5", 2", 2.5", 3",
3.5" and 4" thick. These panels were reused from a previous treatment that became
dated and required a face lift. The panels were 2' wide and 4' high.
The lumber is all 1"x3"
pine furring strips. By providing some air space behind the fiberglass
boards enhances the effectiveness of the absorption characteristics.
The panel shown is 30" wide
and 48" high. The center rear support is to keep the fabric from
causing the side two bow.
The fabric we chose is a deep pile corduroy.
Many different fabrics are usable with the exception of vinyl, plastic or rubberized
yard goods. If you can breath through the fabric it will work
for this acoustic absorber.
STEP ONE: Determine the
size of the panel, measure and cut the 1x3s and form a box or frame. We assembled
all the frames with 1.5" brad nails. (Pneumatic tools are wonderful.)
Adding the 2.5" squares in
the corners provide adequate structural support, along with the center rear
STEP TWO: Measure the
fiberglass boards and trim to size with a sharp utility knife.
STEP THREE: Measure the
fabric and trim to size. The fabric will wrap around to the back side of
the wooden frame. A heavy duty staple gun is used to attach the fabric to
Our usual approach is to attach
the long sides first, keeping the lines of the corduroy square with the wooden
frame. When attaching the second long edge it is important to add a little
tension to keep a tight fit. Once the sides are secured, the shorter ends
can be stapled. Again we add some tension to keep the fabric tight.
STEP FOUR: The corners are then
wrapped around to either the sides or the top and bottom. In this
application the sides of the panels would be visible so we stapled the corners
to the top and bottom.
