[ Click Here ] for additional information. .Sound Seal manufactures acoustic wall and ceiling panel systems. Ceilings are specified in this Section; wall panels are specified in Section 09800. .Acoustical Wood Systems
WoodTrends wood panel systems offer the beauty of real wood with excellent acoustical performance. WoodTrends systems are available in six different systems for walls and/or ceilings in a variety of popular as well as exotic wood veneer species. WoodTrends systems are offered as both absorptive and reflective acoustical systems. Absorption is achieved by state of the art CNC machinery producing a series of elongated perforations (slots) or round perforations with regular or irregular patterns or a series of linear grooves with a perforated or slotted backside. All absorptive panels come with a standard black, non-woven textile acoustical backer. Additional absorption can be achieved by back loading the panels with additional absorptive material. NRC's as high as 0.95 can be achieved. WoodTrends systems are constructed using a MDF core and are available with chipboard or plywood cores. WoodTrends systems are available as Class A rated per ASTM E 84. WoodTrends Panels are finished with 2 coats of clear poly-acrylate UV enhanced lacquer. Custom staining is also available.

          ** NOTE TO SPECIFIER ** 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 26 standard and 40 custom veneers. See perforation options for complete styles. Delete if not required. Refer to Section 09710 - Acoustical Wall Treatment for wall system.
