| Building an oversized curtain
enclosure to reduce and absorb noise has never been a problem. Building an
oversized curtain system without a lot of support columns has always been a
challenge. Until now. A 2 1/2" x 2
1/2" x 3/16" thick heavy duty steel frame that easily supports large
enclosures was developed. A ten foot square curtain enclosure only requires four
corner posts instead of the usual support columns installed at five foot intervals.
A local steel fabricator is very pleased with the results.
According to the shop's engineer, the product grinder was the
most noise offensive piece of equipment in the company's entire operation. Noise
levels exceeded 100 dB(A). Because the unit was relatively small (3' x 4' x 6'), we
knew we could easily reduce the noise level with a curtain enclosure. However, the
steel pieces moving in and out of the roll shop are so big that a full 10' x 10' access
area was required.
The new heavy duty frame system and BBC-13-2" Acoustical
Curtain Panels solved the problem. Even at a height of 10 feet, the enclosure only
required four corner posts - no middle post. Even large fork trucks have easy
access!
The structure was rugged enough to accommodate a partial roof
over the grinder. Because only a partial roof was used, there was no need to
consider ventilation, lighting or sprinkler systems.
The pre-drilled and tapped frame made it quick to assemble
and easy to install.
BBC-13-2" Acoustical Curtain Panels feature a heavy
duty, reinforced loaded vinyl noise barrier exterior and a two-inch thick quilted
fiberglass sound absorption interior. The panels were installed on sliding double
tracks on two sides for quick and easy access. The remaining two sides were attached
directly to the frame thus saving the cost of track and rollers. The result? An
overall noise reduction of 17 dB(A).
In addition to significantly reducing noise levels, the
curtains are durable enough to withstand the punishment we know they'll get in that busy
area.
But we think the most outstanding feature about our new heavy
duty frame is it's versatility. Virtually any large area can now be enclosed without
compromising access. Because the structure is so sturdy and quick to assemble, it'll
go up easily and stay up.
The next time you're confronted with a large, noisy piece of
equipment that looks impossible to enclose with acoustical curtains, don't hesitate.
Think big!

A 10' x 10' acoustical curtain enclosure using only four
corner posts and top cross pieces was built. No middle post, no access problem, no
additional supports necessary!
Our new 2 1/2" x 2 1/2" x 3/16" thick
heavy duty steel frame is rugged enough to support heavy acoustical panels without sagging
or strain to the structure.
Because the frame is pre-drilled , assembly is quick and easy.
The panels were installed on a sliding double track on two sides allowing
complete access to the entire 10'x10' area.
When all was said and done, the overall noise reduction was 17 dB(A).
