APPLICATION
FIRE PERFORMANCE
Conwed Designscape|Wall Technology Low Frequency Tuner
wall and ceiling panels are designed for areas requiring special
control of low frequency sound without over-damping highs.
This is one product with a truly “balanced” absorption across
the entire audio spectrum! Used in critical music practice and
performance areas, often in conjunction with standard A100
Series panels.
Each component has been tested according to ASTM E 84*
and has a Class I/A rating.
CONSTRUCTION
The core construction is a dimensionally stable 6-7 PCF glass
fiberboard with resin hardened edge protection laminated
with a special un-perforated vinyl member that allows selective
acoustical transparency. Fabric finish is completely adhered to
the face of the panel and returned to the back for a full finished
edge. All corners are fully tailored.
RECYCLED CONTENT
Low Frequency Tuner panels can utilize an Owens Corning
fiberglass board core that is third-party certified for recycled
content. The board is certified by SCS to contain at least
57% recycled glass.
And for your LEED® project, our acoustical panels can help
you qualify for recycled content points under the Materials and
Resources section. Other LEED® categories may also apply
depending upon the project requirements.
SIZE AVAILABILITY
The special acoustical purpose of this product requires a 2”
core. Maximum size is 4’x12’.
EDGE DETAIL
All edges are resin hardened, unless otherwise specified.
Available choices include: square, radius, and bevel.
FINISHES
A wide variety of fabrics are available from all major brands,
including Guilford, Maharam, Knoll, Carnegie, and Designtex.
MOUNTING
Standard mountings include spot and perimeter adhesive, Z-clip,
concealed splines, impaling clips, hook & loop, and magnetic
fasteners.
ACOUSTICAL PERFORMANCE
Low Frequency Tuner wall and ceiling panels provide a
balanced acoustical absorption for the common problem of
over-absorption of “highs” and under-absorption of “lows.” The
special under-fabric layer traps lows while selectively reflecting
high frequencies.
WARRANTY
3-YEAR WARRANTY
Low Frequency Tuner panels have a limited 3-year warranty.
The panels are warranted to be free from defects in material
and workmanship for a period of three years from the date of
purchase.
See product warranty for limitations.
* The ASTM E 84 standard should be used to measure and describe the properties
of materials, products or assemblies in response to heat and flame under controlled
laboratory conditions and should not be used to describe or appraise the fire hazard or fire
risk of materials, products or assemblies under actual fire conditions. However, results of
this test may be used as elements of a fire risk assessment, which takes into, account all of
the factors, which are pertinent to an assessment of the fire hazard of a particular end use.
