2. SOUND PANELS

2.1 GENERAL

In order to establish the level of design and quality required, the SonaGuard® Absorptive Noise Barrier System has been designed around the following manufacturer with the following performance specifications:

“SonaGuard® Absorptive Noise Barrier System” manufactured by Sound Fighter Systems, L.L.C., P.O. Box 7216, Shreveport, LA 71137. 318-861-6640

2.2 ACOUSTICAL PANELS

SonaGuard® Absorptive Sound Panels: The panels shall consist of a durable tongue-and-groove glass reinforced thermoset composite structural shell with a UV resistant coating. The panels are also resistant to effects of ozone and freeze-thaw cycles. The front face of the panel is perforated with round holes to create an open area of approximately 25%, and filled with sound absorbing material to increase NRC absorption performance.

A. Longitudinally arranged channel sections on the bottom of the panel form a tongue and groove interlock joint when stacked.

B. End connections shall be a tongue and groove design to fit into a 2-7/8 slot created on an appropriately-sized beam. No screws or bolts are needed to install the panels to structural steel columns.

C. Internal absorptive fill material shall be 6.0 pounds per cubic foot density mineral acoustic fiber packed under not less than 5% compression to eliminate voids. It shall be moisture and corrosive resistant, vermin proof, non-combustible, smokeless, and odorless. The mineral fiber fits into the panel cavity against the perforated face.

D. Physical Properties:

i.Width: The maximum nominal width of panels shall be specified on each order.

ii.Height: The tongue and groove panels are a nominal height of 12 inches each.

iii.Thickness: The panels shall have an overall thickness, measured on the panel ends, of 2.75" maximum.

iv.Weight: The finished panels shall not weigh more than 5 lbs per sq/ft

E. Mechanical Properties:

The panels shall have minimum mechanical properties as follows:

F. Color:

The Customer shall specify the color. The panels shall be coated with a UV resistant polymer.

G. Temperature Resistance:

When assembled per manufacturer’s instructions, the panels shall not exhibit any cracking, deformation or separation when cycled from a temperature of -40o F to +140o F and back again.

H. Flame Resistance:

The panels shall have a Class C flame rating; enhanced ratings of Class B or Class A available when required.

I. Acoustic Performance:

i.Noise Absorption: The panels shall have a noise reduction coefficient of 1.05 or greater according to ASTM Test Method C423-90a.

ii.Sound Transmission: The panels shall have a sound transmission class of 35 or greater according to ASTM Test Method E90-90 and E413-87.

3. STEEL FABRICATION

A. All structural steel design, fabrication and erection shall conform to the latest edition of the AISC manual of steel construction, “Allowable Stress Design”.

B. Steel for wide flange shapes and built-up column members shall conform to ASTM A572 Grade 50 or ASTM A992. All other structural steel base plates and braces shall conform to ASTM A36.

C. All anchor bolts shall conform to ASTM A36 galvanized unless noted. The anchor bolt length will depend on the type of anchor used.

D. All welding shall conform to American Welding Society D1.1 and Electrodes shall be E70XX.

E. All fabricated steel members are to be hot dip galvanized after fabrication per ASTM A123 unless otherwise noted.

F. Steel columns shall be spaced to accommodate the panel length.

G. All support steel and foundations shall be designed to meet the wind load requirements, wall height and soil conditions for each specific wall project and location. Soil conditions and footing design will vary depending on location of wall system. Each wall project will be uniquely designed because of this.

4. INSTALLATION

A. The SonaGuard® Absorptive Noise Barrier System shall be installed per the manufacturer’s recommendation to the lines and grades shown in the contract documents or otherwise specified.

B. Environmental Requirements:

i.Do not install structural steel until concrete and anchors have been set and cured.

ii.Do not install sound panels until structural steel has been anchored and plumbed.

C. Manufacturer's Installation Instructions:

i.Comply with manufacturer’s product data, including product technical bulletins, product catalog installation instructions and product carton instructions for installation.

ii.Extreme care shall be exercised to protect the wall components from damage during shipment or erection.

iii.The installer shall, before ordering any wall component, inspect the job site and verify in writing to the manufacturer that site conditions permit the original plan of installation and erection of wall components.

a.Verify that center distances for structural steel columns are per manufacturer’s exact specifications.

b.Do not install SonaGuard® sound panels until unsatisfactory conditions are corrected.

c.Installer shall identify any underground utility or overhead obstruction that could affect job site safety. The installer is responsible to correct any site conditions that would compromise site safety and cause an accident.

iv.Installer is responsible for accepting and inspecting delivered components prior to installation.

v.The installer shall notify the manufacturer of any wall components received in damaged condition. Any damaged wall component installed without proper manufacturer notification and site inspection is the responsibility of the installer.

vi.Installer acknowledges the importance of accurate footing and post spacing. A spacing to large or too small will require either an extra footing/post or customized panels from the manufacturer, which may result in the need to have the wall inspected by an engineer for approval for structural stability.

5. MAINTENANCE

No routine maintenance (painting / staining) is required with the SonaGuard® System. Most graffiti (paint) can be washed off with minimal effort via the use of a mild, citrus-based cleaning solvent.
