Acoustic Enclosure Systems

Panel enclosure systems shall be insulated double-wall construction and shall be provided as indicated on drawings. Panels, components and accessories shall be provided by a recognized manufacturer with published standards of construction and technical performance. The manufacturer shall have produced a standard factory-fabricated panel system and components for at least 10 years. Performance of the fabricated and installed system shall conform to all specifications listed herein.

All panels and their components shall be pre-fabricated, sectional, all-metal clad, modular and designed for easy and accurate field assembly. The panels and components shall not be susceptible to damage due to extended exposure to vibration, air temperature or humidity with the passage of time.
Panel Construction

All panels shall be (4) / (6) inches thick, as noted on drawings, with a solid galvanized steel type G90 exterior shell, a septum skin and a perforated/solid galvanized steel type G90 interior shell. The panels shall be connected together by means of a tongue and groove connection and held together rigidly by the use of self-drilling sheet metal screws, to be installed on maximum 18" centers on the inside and outside of the enclosure.
The panel shells, framing members, and internal reinforcements shall be welded and/or riveted together to form a metal-sheathed panel of sufficient strength for maximum operating loads specified in the structural performance section of these specifications.
The outer galvanized steel shell thickness shall be 16 ga. minimum and the inner galvanized steel shell shall be 22-ga. minimum thick.
Where perforated materials are indicated, all perforations shall be 3/32" dia. holes on 3/16" staggered centers and shall result in an open area of no less than 23 percent.
All panel internal and external reinforcing members shall be minimum 18 ga. galvanized steel.
Each panel shall be filled with sound-retardant and absorbing materials that are inert, mildew-resistant, verminproof and incombustible.
Where indicated on drawings, septum panels shall consist of a solid 16 ga. minimum galvanized outer skin, a septum skin and a 22 ga. minimum galvanized inner skin.

All accessory trim items shall be of 18 ga. minimum galvanized steel and shall be furnished in factory- standard lengths to be field cut to specified dimensions. Locations and quantity of sheet metal screws and trim requirements shall be in accordance with the manufacturer’s installation details.
Base channel shall be installed on a level and true steel or concrete surface.
All external panel connectors, trim items, accessories, base channel/panel interfaces/base channel/floor interfaces, and other sections as noted on the drawings shall be sealed with an acoustical sealant that shall not harden and prevent disassembly in the future.

Any special external panel loading conditions including wind, snow and equipment shall be provided for as per specifications.
Under the indicated loading conditions, the entire enclosure system shall be self-supporting and/or will be supported as per the specifications. The installer shall furnish and assemble all structural members in strict accordance with drawings and manufacturer’s installation details.
Under the above loading conditions, the assembled acoustical structure shall not exhibit any panel joint deflection in excess of L/240, where L is the unsupported span length of any panel section in the erected structure.

The manufacturer shall provide certified testing data indicating sound absorption and transmission loss characteristics of the panel assembly.

Doors, windows, electrical systems, ventilating systems, accessory components, etc., shall be provided in accordance with drawings.

All materials shall be provided by Kinetics Noise Control, Inc. - Vibron Products Group.
