PART 2 PRODUCTS

2.1 WINDOW BLINDS

2.1.1 Provide each blind, including hardware, accessory items, mounting brackets and fastenings, as a complete unit produced by one manufacturer. All parts must be one color, unless otherwise indicated, to match the color of the blind slat. Treat steel features for corrosion resistance.

2.1.1.1 Horizontal Blinds

a. Provide horizontal blinds with 2 inch or 1 inch slats as indicated. Blind units must be capable of nominally 180 degree partial tilting operation and full-height raising. Blinds must be inside or outside mount as indicated. Furnish tapes for Type I slats with longitudinal reinforced vinyl plastic in 1-piece turn ladder construction. Tapes for Type II slats must be braided polyester or nylon.

(1) Head Channel and Slats

(a) Provide head channel made of steel or aluminum with corrosion-resistant finish nominal 0.018 inch for Type I or 0.024 inch for Type II. Provide slats of aluminum, not less than 0.008 inch thick, and of sufficient strength to prevent sag or bow in the finished blind. Provide a sufficient amount of slats to assure proper control, uniform spacing, and adequate overlap. Enclose all hardware in the headrail.

(2) Controls

(a) The slats must be tilted by a transparent tilting wand, hung vertically by its own weight, and must swivel for easy operation. The tilter control must be of enclosed construction. Provide moving parts and mechanical drive made of compatible materials which do not require lubrication during normal expected life. The tilter must tilt the slats to any desired angle and hold them at that angle so that any vibration or movement of ladders and slats will not drive the tilter and change the angle of slats. Include a mechanism to prevent over tightening. Provide a wand of sufficient length to reach to within 5 feet of the floor.

(3) Intermediate Brackets

(a) Provide intermediate brackets for installation, as recommended by the manufacturer, of blinds over 48 inch wide.

(4) Bottom Rail

(a) Provide bottom rail made of steel, corrosion-resistant, with baked-on polyester paint, color coordinated with slats, and formed with a double-lock seam into a closed oval shape for optimum strength. Provide end caps to match the rail in color.

(5) Braided Ladders

(a) Provide braided ladders of 100 percent polyester yarn of a color to match the slat color. Space ladders a maximum of and a minimum 15.2 slats per foot of drop in order to provide a uniform overlap of the slats in a closed position.

(6) Hold-Down Brackets

(a) Provide universal type hold-down brackets for sill or jamb mount where indicated on placement list.

2.2 COLOR

Provide color, pattern and texture as indicated on the drawings or as selected from manufacturer's standard colors. Color listed is not intended to limit the selection of equal colors from other manufacturers.

PART 3 EXECUTION

3.1 IDENTIFICATION

3.1.1 In accordance with the numbering plan, mark each opening and the corresponding window treatment with identical numbers. For multiple windows separated by mullions, the space required by each blind must be numbered separately. Use brass, aluminum, plastic, durable paper plates, or stamp to place corresponding numbers on unexposed surfaces of openings and inside or on top of the headrail track.

3.2 INSTALLATION

3.2.1 Horizontal Blinds

3.2.1.1 Perform installation in accordance with the approved detail drawings and manufacturer's installation instructions. Install units level, plumb, secure, and at proper height and location relative to window units. Furnish and install supplementary or miscellaneous items in total, including clips, brackets, or anchorages incidental to or necessary for a sound, secure, and complete installation. Do not start installation until completion of room painting and finishing operations.

3.2.2 Valance

3.3 CLEAN-UP

3.3.1 Upon completion of the installation, free window treatments from soiling, damage or blemishes; and adjust them for form and appearance and proper operating condition. Repair or replace damaged units as directed by the Contracting Officer. Isolate metal parts from direct contact with concrete, mortar, or dissimilar metals. Ensure blinds installed in recessed pockets can be removable without disturbing the pocket. The entire blind, when retracted, must be contained behind the pocket. For blinds installed outside the jambs and mullions, overlap each jamb and mullion 0.75 inch or more when the jamb and mullion sizes permit. Include all hardware, brackets, anchors, fasteners, and accessories necessary for a complete, finished installation.
