Eurospan Ceiling System C. Eurospan Ceiling System Fabric Mounting Devices: Rigid polymer high strength extrusions or aluminum extrusions for perimeter and mid seam profile tracks. 1. Track Height: [1] [1-1/2] inch nominal. 2. Perimeter Track Edge: [Square] [Bevel]. a. Cover exposed edges with matching fabric. b. Paint exposed edges, color to match the fabric. 3. Mid Joint Track Edge: [Square] [Reveal]. a. Flexible for achieving curved lines, or conforming to concave or convex surfaces. b. When core material is thicker than track profile, provide wood "grounds" or furring strips prior to mounting the track. 1) Provide fire retardant treated wood where required by Code. 2) Cover exposed edges with matching fabric. 3) Paint exposed edges, color to match the fabric. 4. Anchoring System: Provide 18 gauge wire staples with mechanical ability to diverge staples for attaching extrusions or other fastening systems, as approved by manufacturer. PART 3 - EXECUTION 3.1.1.1 EXAMINATION A. Examine the condition of the substrate and the conditions under which the work of this Section is to be performed. Notify the Contractor in writing of any unsatisfactory conditions. Do not proceed with the work until unsatisfactory conditions have been corrected in a manner satisfactory to the installer. B. Field measures each area which is to receive the ceiling system to establish the correct layout. 3.1.1.2 INSTALLATION A. Install materials in accordance with manufacturer's instructions, and comply with governing regulations, fire resistance rating requirements, as indicated, and industry standards applicable to the work. B. Apply the rigid mounting system tracks to surfaces that are to receive the treatment. Secure with pneumatic stapler using 1-inch staples spaced on 2-inch centers. 1. Other fasteners may be used as may be required for specific substrates, providing they are in accordance with the manufacturer's instructions and comply with governing regulations and fire resistance rating requirements specified. C. Install mounting system tracks level and straight, flush and in proper alignment. D. Install the acoustical core material, continuous and flush to the edge of the track in largest sizes practical and secure in place with appropriate staples or screw fasteners. 1. If the fabric is to be closer than " to the core then the joints shall be caulked and/or a white scrim or lining shall be used to prevent "read through." The scrim or lining shall not inhibit the acoustical performance of the system and meet all the necessary fire safety code requirements. E. Shop cut the fabric slightly over-sized for each area to be covered. Label each piece and package, loosely folded, in clean containers for transportation to job site. Larger projects may require full rolls to be shipped to the job site where a clean cutting and staging area must be maintained. F. Stretch the fabric and secure into the locking jaws so that it will be smooth, free of wrinkles or puckers. Trim off excess fabric at perimeter and tuck remaining material into storage channel of the extrusion. FABRIC WRAPPED CEILING PANELS 09 54 46 - 3
