	** NOTE TO SPECIFIER ** Sound Seal; wood-veneered acoustic wall panel systems. . This section is based on the products of Sound Seal, which is located at: 50 H.P. Almgren Dr. Agawam, MA 01001 Toll Free Tel: 800-569-1294 Tel: 413-789-1770 Email: request info Web: www.soundseal.com [ Click Here ] for additional information. . Sound Seal manufactures acoustic wall and ceiling panel systems. Wall panels are specified in this Section; ceilings are specified in Section 09570. . Acoustical Wood Systems WoodTrends® Wood Systems offer the beauty of real wood with excellent acoustical performance. WoodTrends systems are available in six systems for walls or ceiling in many standard wood specie selections. WoodTrends systems are offered as both reflective and absorptive acoustical systems. Absorption is achieved by a series of slots, grooves, or perforations with standard or custom patterns available. All acoustic panels come with a standard black non-woven textile acoustical backing. Additional absorption can be achieved by back-loading with additional absorptive material. All WoodTrends products are available as Class A rated per ASTM E 84. . Acoustical Wood for Walls WoodTrends® Standard is a plank style wall treatment utilizing either perforations or grooves to achieve NRC values as high as .95. Standard Wall Panels are manufactured with either an MDF or chipboard core, and real wood veneer, finished with two coats of a UV-Polyacrylate lacquer. Many standard and exotic veneer species are available. Installation is typically by nail clip onto furring strips. A REVEAL EDGE-detail leaves a 5, 10 or 20mm groove between planks. This groove is typically filled with a real wood strip (provided) to hide the nail clip. A FLUSH EDGE-detail requires no wood strip as the edges butt together. A 2 mm bevel typically defines the seam between planks. . Tongue & Groove Plank System for Walls WoodTrends® Topline is a plank style wall treatment utilizing a series of grooves and slots to achieve acoustic results. Built on a 16mm thick MDF with a veneer thickness of .6 mm, it is typically finished with two coats of a UV-Polyacrylate lacquer.-Plank edges are in tongue and groove configuration to provide a monolithic finished look. Installation is by the use of nail clips onto furring strips. Topline Panels can also be installed on wood framed ceilings. Topline panels are also available in many standard and exotic veneer species. Five different groove patterns along with varying thicknesses and densities of backing materials provide for many acoustical options. . Tongue and Groove Plank System for Walls WoodTrends® Timbre is a plank style wall or ceiling treatment utilizing a channeled chipboard core with acoustic results depending on the number of channels relieved by grooves. Built on either a 24 mm or 31 mm thick base material with a veneer thickness of .6 mm, it is typically finished with two coats of a uv-polyacrylate lacquer.-Plank edges are in overlap configuration to provide a monolithic finished look. Installation is typically by gluing and nailing to furring strips. Timbre Panels are available in many standard and exotic wood species.
