PART II - PRODUCTS

2.01 Manufacturer and Product Description

A. Acceptable product: LouverDrape Zirlon Wheeled Vertical Blind System manufactured by Levolor Home Fashions.

B. Materials:

  1. Headrail shall be of extruded anodized aluminum alloy 1-5/16" wide x 1-7/16" high with capped ends, provided with Delrin, or equal, sprocket wheels. End caps shall be equipped with covers to enclose sprockets and rotation rod ends and rollers for traverse cord.
  2. Carriers shall be made of Delrin, 5/16" wide and traverse on Zirlon wheels to reduce draw force. No glides or sliders shall be allowed. The vane stem shall be of snap-out design to yield when subjected to interference without damage to the blade or any part of the carriage assembly. The stem shall be replaceable without demounting headrail.
  3. Spacer links of flexible stainless steel 1/4" wide shall space and stabilize carriers by passing smoothly between stabilizer guides on each carrier.
  4. Vanes shall rotate 360 degrees and pack, when traversed, into no more than 5/16" per vane. When rotated, 2-1/8" vanes shall overlap not less than 1/4"; 3-1/2" vanes shall overlap not less then 3/8".
  5. Rotation mechanism shall consist of a #6 nickel-plated bead chain to synchronize and actuate 360-degree rotation by turning a keyed aluminum rod actuating Delrin worm and spur gear in each carrier. Gears shall provide no less than 8-to-1 mechanical advantage and keep vanes fixed until reset by control. No cord or 1-to-1 ratio mechanisms will be allowed. Spur and worm gear shall slip under extreme loading and be able to be realigned with no damage.
  6. Traversing mechanism shall allow vertical blinds to traverse left to right, right to left or split. Blinds shall traverse by means of a non-stretch traverse cord. With the AutoWand option, vertical blinds shall traverse left to right or right to left by means of a composite plastic wand.
  7. Cord Weight shall be of molded ABS plastic filled for weight. Cord weight shall be readily removable without detaching cord from headrail.
  8. End Caps: Control and return end cap assemblies shall be molded to match aluminum extrusion profile and provide contemporary aesthetic appearance.
  9. Installation Brackets shall be provided for overhead or surface installation using thumb clamps and angle brackets. Brackets shall be designed to facilitate installation and removal of track.
  10. Vane Spacing: A nylon spacer arm integral with the carriage body shall be used to provide visually uniform vane spacing when the blind is fully drawn. Normal vane spacing on center is a fraction of an inch less than the vane size. For example:
      Vane width: 2-1/8" Spacing on center 1-3/4"
      Vane width: 3-1/2" Spacing on center 3-1/8"
  11. Vanes shall be selected from the following (select one): Control location and Stack Draw must be specified.
    a. Vanes shall be extruded of 100% GEON solid vinyl or equal. The vinyl shall also contain ultra violet inhibitors. Calcium carbonate content will not exceed 15% on standard colors. Vanes shall withstand 140 degree heat chamber for thirty minutes without distortion, and with no more shrink and stretch and 1/2 of 1%. A ten-foot vane suspended from the center of one end shall hang straight with no twist, warp or bow. Vanes shall be permanently flame resistant, if unaltered.

    Vanes shall be selected from the following:
    1. Nominally 2-1/8" wide. Perforated option available.
    2. Nominally 3" wide.
    3. Nominally 3-1/2" wide. Perforated option available.
    4. Nominally 4-3/8" wide
    5. Nominally 5" wide

    An optional keyhole punch with a corrosion-free chain may be specified to control swaying and keep unit functioning as a whole.

    b. Fabric vanes shall be available in two styles:

    1. Free Hanging: Vanes shall be free hanging woven or slit to 2-1/8" or 3-1/2" (select one) wide, and color fast. Vanes shall have a steel weight inserted into a sewn pocket at bottom of vane. An optional clip-on corrosion-free, nickel-plated steel chain shall be attached to weights to control swaying and keep unit functioning as a whole (if specified). Certificate of flame resistance must be provided.
    2. EverClear Louver Groover: Vanes shall be of colorfast fabric slit to appropriate width, slid into groover channel. Groover shall be extruded of 100% GEON vinyl or equal and shall be guaranteed not to crack or yellow for six years. Groovers should have clear edges that hold fabric in place. Certificate of flame resistance must be provided.
  12. Options shall include:
    a. Zirlon with AutoRotate: additional specifications include
    1. Vanes shall rotate 180 degrees and stack, when traverse, into no more than 5/16" per vane. When rotated, 2-1/8" vanes shall overlap not less than 3/8"; 3-1/2" vanes shall overlap not less than 3/8". Adjustments can be made to allow a 360 degree rotation.
    2. Auto Rotation is activated by traverse cord being spooled on sprocket extension. When traversing is attempted with vanes in closed position, the spool is turned rotating the rotation rod and opening vanes before traversing. Self-alignment is not acceptable.

    b. Zirlon with AutoWand: additional specifications include

    1. AutoWand Rotation consists of a fiberglass wand with Lexan handle to synchronize and actuate 360 degree rotation through a keyed aluminum rod actuating Delrin worm and spur gear in each carrier. Gears shall provide not less than 8-to-1 mechanical advantage and keep vanes fixed until reset by control. No cord or 1-to-1 ratio mechanism will be allowed. Spur and worm gear shall slip under extreme loading and be able to be realigned with no damage.
    2. Traversing of vertical blinds shall be left to right or right to left. A fiberglass wand with Lexan handle shall traverse the lead carrier and gear assembly.

    c. Headrail color: Anodized aluminum is the standard headrail color. Deep Bronze and Ivory are also standard colors available for a minimal per foot upcharge. Custom colors are available at an additional charge.
