Division 9 Ebook Page 95 Low Frequency Tuner

Product Data Sheet LOW FREQUENCY TUNER WALL AND CEILING PANELS APPLICATION 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. 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. 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. The following noise reduction coefficients were derived from tests in accordance with ASTM C 423 on a Type D5 mounting. NRC rating is 0.35. Frequency-HZ Absorption Coefficient 250 0.32 500 0.42 1000 0.27 2000 0.18 SAA 0.32 NRC 0.30 FIRE PERFORMANCE Each component has been tested according to ASTM E 84* and has a Class I/A rating. 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. 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. Values are reported to the nearest 5 rating.
