ULTRASCREEN:
Sight and Sound Barrier
The Need
| |
Panels have been widely used for
many years to act as sight and sound
barriers in most of the highways and
in residential areas where visual
privacy is needed. Also, panels are
used by persons living close to
roadways and where it is desirable
to minimize distractions caused by
noise. The need of privacy fencing
around commercial property and
residential areas most of the times
can be satisfied with cement or
wood panels among others. |

UltraScreen Panels. |
The Technology
| |
The United States Gypsum Company,
early in the 1980's started
developing technologies to improve
and reduced costs using lightweight
cement panels. Recently, USG along
with AFM Corporation/R-control
introduced ULTRASCREEN: Sight and
Sound Barrier. This lightweight
panels require no special equipment
for installation, maintenance, or
replacement making them beneficial.
This latest development also creates
a system with good acoustical
performance and excellent strength
to weight ratio.
The USG (United States Gypsum
Company) pioneered major advances in
the development of Durock Cement
Board, which is an aggregated
portland cement board reinforced
with a polymer-coated glass fiber
mesh. These panels have been of wide
acceptance for a huge number of
systems used to clad the exteriors
of residential and commercial
structures all over the North
America.
The Sight and Sound Barrier panel
are sold under the name ULTRASCREEN.
The panels consist of a perform
guard termite, mold, and mildew
resistant EPS foam core with DUROCK
cement board laminated to both
sides. The panel may contain steel
strip or similar structural
reinforcement sandwiched between the
Durock and foam. The panel can be
engineered to resist a specific
design wind load by varying the
panel thickness, reinforcement or
number of cement board layers. The
Sight and Sound Barrier (SSB) is
pre-finished with a number of
finishes including Stone or Exterior
Texture Finish. |

Another attractive feature of the
panels is its low cost

Easy
Panel Installation.

Installation in Libertyville, where
curved walls were used. |

The SSB panels are designed to be
slid into place between steel or
pre-cast concrete wide flange
columns, and stacked to the desired
height. Standard panels are
approximately 4 feet tall and 12
feet long, but can be customized to
suit specific project requirements.
Panel edges interlock, and are
factory coated at this horizontal
joint. The top panel is then
finished across the top of the EPS
Form core. Due to their light weight
(a panel of 4' x 12' weighs 450
lbs.) the panels are lifted using a
conventional boom truck and a
function clapping jersey - wall
lifting unit.
This system is typically designed to
be used without a panel to post
connection. For the more typical
case where the panels is
friction-fit between the columns, a
high density polyethylene or hard
rubber shim is used to close the
small gap between the panel and the
column. In the absence of this panel
to post connection, the system is
designed to ensure that all the
loads are adequately transferred
from the panel to the post, and that
there is no possibility of slipping
out. Also, this system has many
features that withstand the harsh
environment in which it will be
placed. For example, the exterior of
the panels include: perform guard
top panel is finished, the EPS foam
at the panel ends is coated with a
weather resistant elastomeric
finish. All of the above to protect
it from ultraviolet degradation,
exposure to road salts, corrosion,
etc. |
The Benefits
| |
-
These light weight panels, can
be quickly and easily installed
using a boom truck. It takes
much less time to install than
masonry, therefore reduces
traffic interruption for
construction.
-
All the components of the
panels, are made from abundant
raw materials and have recycled
ingredients, such as fly ash,
and recyclable products such as
plastic and steel.
-
ULTRASCREEN acts as a sound
barrier because panels are
sound-reflective and can be
designed to provide even greater
noise reduction by adding
additional Durock Cement Board
face layers.
-
Another attractive feature of
the panels is its low cost,
because they are more
inexpensive than current systems
of screens. The costs are also
reduced because of the system's
rapid speed of installation.
-
With the field installations it
was demonstrated that signage
can be bonded to the system
successfully and how curved
walls can be created to enhance
design possibilities.

Status
| |
The performance assurance of
ULTRASCREEN Sight and Sound Barrier
was put to the test at USG Research
Center in Libertyville, Illinois and
at the USG plant at Santa Fe
Springs, California.
The next step in the development
process was to have the system
evaluated by an independent
engineering firm. Thus, ULTRASCREEN
underwent a two year evaluation by
the Highway Innovative Technology
Evaluation Center (HITEC) of the
Civil Engineering Research
Foundation (CERF). Five trial
installations were inspected during
or immediately following the
installation by the HITEC
consultants. The installations range
in size from four test panels
erected in Toronto, Canada, to a 110
panel installation installation on a
bridge along State Route 17 in
Courning, New York. The sites were
selected to cover a broad range of
geography and site conditions. |
