Install stretched-fabric systems according to system manufacturer's written <br />instructions. <br />1. Provide continuous perimeter frames of each profile indicated, designed to be <br />inconspicuous when covered by fabric facing, with smooth edges, and with <br />surface finish that will not telegraph through fabric facing. <br />2. Install framing around penetrations. <br />3. Tightly fit framing to adjacent construction and securely attach to substrate. <br />4. Install core material with full coverage, flush with face of stretched-fabric <br />system frame. <br />5. Attach frame and core to substrate with adhesive or fasteners, or both, to <br />support system and prevent deformation of components. <br />6. Install stretched-fabric systems true in plane and with fabric square to the <br />grain. <br />7. Install jointed panels with butt joints and reveals as indicated. <br />B. Fabric Installation: Apply fabric monolithically in continuous run over area, without <br />joints or reveals, except where panel joints or midspan frames are indicated. <br />1. Fabric Direction: Run fabric as indicated on Drawings. <br />2. Fabric Sequence: Maintain sequence of fabric drops; match and level fabric <br />pattern and grain. <br />3. Fabric Alignment: Install fabric with patterns or directional weaves so pattern <br />or weave aligns with adjacent panels. <br />4. Fabric Seams: Sewn seams are not permitted. <br />5. Stretch and secure fabric to frame edges and so frame and frame attachment <br />method are concealed by fabric unless otherwise indicated. <br />6. Stretch fabric tightly and square without puckers, ripples, or distortions. <br />Acclimatize and restretch if recommended by stretched-fabric system <br />manufacturer. Repair distortions, wrinkles, and sagging. <br />3.4 INSTALLATION TOLERANCES <br />A. Edge Straightness: Plus or minus 1/16 inch in 48 inches. <br />B. Variation from Alignment with Surfaces: Plus or minus 1/16 inch in 48 inches, <br />noncumulative. <br />C. Variation from Level or Slope: Plus or minus 1/16 inch. <br />D. Variation of Joint Width: Not more than 1/16 inch in 48 inches from hairline or <br />reveal line, noncumulative. <br />3.5 CLEANING <br />A. Clip loose threads; remove pills and extraneous materials. <br />B. Clean panels on completion of installation to remove dust and other foreign <br />materials according to manufacturer's written instructions.
