Product Data Sheet RESPOND DIFFUSERS: BARREL AND PYRAMIDAL DESCRIPTION & USES Conwed Designscape Wall Technology Diffusers are designed for use in performance areas, auditoriums and other facilities requiring enhanced quality and acoustical performance. Diffusers scatter and blend sounds for a broad range of frequencies and improve the quality of music environments. By reflecting and absorbing sounds, diffusers blend the sound field in a room resulting in a more pleasant listening experience. Various sizes of barrel and pyramidal diffusers are available to meet the most demanding project needs. These rugged and easy to install diffusers are supplied with hardware for either wall or ceiling applications. COMPOSITION Diffusers are constructed of 1 /8" thermoformed fire resistant plastic, and are molded to a one-piece barrel or a special offset pyramidal shape. The surface is white and lightly textured, or, fabric can be applied directly to the face forming a full finished edge with tailored corners. The internal portion can be lined with a 1- 1 /2" thick layer of glass fiber batt to enhance sound absorption. AVAILABILITY Diffusers are offered in a white lemon peel texture, or are available with fabric coverings. Contact Conwed Designscape Wall Technology for available fabrics and colors. Barrel Diffuser first dimension indicates the faceted side. * These sizes are available in rigid fiberglass only. Custom shapes and sizes are available upon request. PHYSICAL PROPERTY DATA Surface burning characteristics: Components have been tested in accordance with ASTM E84* and determined to have a Class I/A rating. EXCELLENT ACOUSTICAL PERFORMANCE Our products are constantly modified to achieve their maximum acoustical performance while providing the aesthetics desired in their applications. Panels are available in a variety of thickness, and their performances are tested in accordance to ASTM procedures in a NVLAP accredited laboratory. Please consult with your Sales Representative, or the Company's Technical Services Department for assistance in determining the proper panels, and their acoustical specifications, for your application. NOISE REDUCTION COEFFICIENT The NRC value for each product was determined in conformance with Test method ASTM C 423, using the D5 mounting (5mm airspace): Pyramidal NRC 4'x4' Thermoformed .10 Barrel NRC 4'x4' Thermoformed .10 Data is also available upon request for fabric covered, insulated interior and other mounting configurations. MOUNTING Wall Diffusers, which have a straight edge, mount using a combination of L-angles and hook and loop fasteners. Ceiling Diffusers normally come in a flanged configuration to fit standard-sized ceiling grid. Note that internally lined diffusers require heavy-duty grid. Optionally, Ceiling Diffusers can be supplied with straight edge and L-angles for direct mounting to solid surfaces. WARRANTY 3-YEAR WARRANTY 3-year limited warranty against manufacturing defects. See product warranty for details and 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. Type Nominal Size Pyramidal 2' x 2' 2' x 4' 4' x 4' Barrel 2' x 2' 2' x 4' 3' x 3' 4' x 2' 4' x 3' 4' x 4' * 4' x 8' * 6' x 3' * 6' x 4' * 8' x 4'
