2.2.1.2 Drapery Lining

None; At privacy curtains, mount two drapes back-to-back for finished appearance on both sides at each location to receive privacy drapes.

2.2.1.3 Flame Resistance

NFPA 701 . Drapery fabric and lining must pass the small and large scale test. Treatment to enhance flame resistance must be permanent type. If treated, fabric must pass the small and large scale test after being subjected to the accelerated dry cleaning or laundering cycles specified in NFPA 701 .

2.2.2 Sewing Thread

Pre-shrunk mercerized cotton (50/3) or monofilament in equivalent size, except do not use monofilament in the heading.

2.2.3 Heading

2.2.3.1 Heading Hooks

Slip-in-type, nickel-plated steel, and of a size adequate to hold the heading upright. Provide one hook for each pleat. Provide 10 percent surplus hooks for possible lost or damaged hooks.

2.2.3.2 Snap-Tape System (Ripplefold)

Heavy vinyl or nylon tape with locking fasteners attached to tape to form desired pleat spaces and fullness. Cut tapes to size and sew to drapery fabric to form the heading.

2.2.4 Drapery Hardware

At Privacy Curtains provide ceiling mounted tracks of heavy-duty type.

Traverse rods or tracks must be manually operated, one-way draw . Rods and tracks must be cold-rolled, commercial quality steel minimum 0.030 inch thick or extruded aluminum minimum 0.050 inch thick. Rod and track cross section width and depth must be sufficient to carry the drapery without

SECTION 12 22 00 Page 4 sagging. Track configuration (number of channels) must be such so as to permit drapery operation as specified or indicated. Finish steel components with a white baked enamel, vinyl, or epoxy coating as standard with the manufacturer. Finish aluminum components with an anodic clear (natural) coating as standard with the manufacturer. Provide smooth and non-sticking sliding surfaces. Provide one-piece rod and track up to 16 feet long. Provide steel brackets and intermediate supports. Provide one manufacturer's design throughout.

At Thermal Curtains in Datacenter/Server Rooms provide aluminum tracks designed to receive clear urethane curtains, attached to acoustical ceiling grid, including pre-fabricated corners and shapes required for continuously sealed installation.

2.3 FABRICATION

Prior to cutting and fabrication, field measure each drapery location paying particular attention to field conditions affecting the work.

2.3.1 Drapery Fabrication

2.3.1.1 Panels

Privacy Curtains: Make from full or half widths of fabric to give a minimum of 120 percent fullness. 120 percent fullness is defined as 1.2 times the rod width plus overlaps and returns. Provide ripplefold.

Draperies must be floor length. Floor length draperies must hang 1 inch above finish floors. Provide table-sized drapery panels with a plus or minus tolerance of 1/4 inch accurately laid-out before cutting. Cut fabric to allow for pleats and for outside ends to return to the walls.

For traverse draperies, allow for a minimum overlap of 3 inches at the center. Accurately match patterned fabrics to provide identical designs horizontally and vertically on each window within each room. Where variations in length or placement of windows occur in a room, match patterns horizontally. When fabricating panels from fabrics which require special methods or instructions, conform to the workroom instructions provided by the fabric manufacturer. Sew seams and hems using a firm interlocking stitch at a stitch rate per inch appropriate to fabric being sewn. Sew with enough slack present so that thread shrinkage due to laundering and dry cleaning will not pucker seams and hems. Do not expose seam and hem raw edges.

2.3.1.2 Headings

Pleat evenly to required widths. Make headings 4 inches high with triple french pleats, and double fold. Include permanent finish stiffener of buckram, crinoline, or pellon across entire heading. Paper stiffening is not acceptable. Machine stitch pleats for a depth of at least 3-3/4 inches.

Do not use horizontal stitching across the width of the heading.

SECTION 12 22 00 Page 5

2.3.1.3 Seams

Join widths by serging, overlock, and safety stitch. Retain selvage when practical.

2.3.1.4 Hems

Double fold hems (top and bottom) and blind stitch so as not to show on the panel face. Make side seams 1-1/2 inches wide and bottom seams 4 inches deep with weights sewn 1/2 inch above hem bottom. Provide weights at corners and each vertical seam. When lining is attached to the drapery fabric, single fold heading is acceptable, however, double fold the bottom hem.

2.3.2 Thermal Curtains

Fabric to ensure continuous seal at top and bottom of curtains. Ensure that curtains are of sufficient length to achieve seal at raised access floor surfaces.

PART 3 EXECUTION

3.1 EXAMINATION

Ensure that work of other trades and cleaning operations are completed.

Test completed installation to ensure smooth and continuous operation of all draperies, hardware and accessories.

3.2 INSTALLATION

Install draperies in rooms and areas indicated . Include all material indicated, specified, or necessary for a complete finished drapery installation. Contractor is responsible for the required quantities of draperies and hardware.

Do not install building construction materials that show visual evidence of biological growth.

3.2.1 Hardware

3.2.2 Draperies

Install with a minimum clearance of 1/4 inch between the ceiling and top of drapery heading. Floor length draperies must hang 1 inch above finished floors; sill length, 1/2 inch above window sills and heating-air conditioning units; and apron length, 1 inch below bottom of window aprons. Insert heading hooks at rear of each pleat, placed to obtain the clearance specified. Press well before hanging, except fiberglass.

Dress-down and adjust hung draperies to provide best form and appearance.

Traverse draperies must operate smoothly and easily over the full range of travel. Remove incorrectly sized drapery and remake to correct size.

Remove damaged, spotted, or otherwise defective fabric and repair to original state or replace with new material.
