Optium's SC7650 Series

The Window Man is pleased to carry Optimum's steel vertical sliding windows. Optimum's SC7650 Series carry either an MEA and or Underwriters Laboratories, Inc. (UL) label for fire resistance rating of 45 minutes, in accordance with the standards for Fire Tests of Window Assemblies, ANSI/ UL9 (NFPA 257, ASTM El63).

All principal cold rolled formed members are ASTM A528 Low Carbon Steel. Frame members have a minimum thickness of 20 gauge.

Sliding sash panels have EPDM gaskets throughout the entire perimeter (unless otherwise noted).

All units are reasonably free from scratches and blemishes and have the following:

* Zinc Coating (ASTM A525 Z200) on both surfaces, applied by a continuous hot dipped process (The Sendzimir System), followed by a "skin pass" (smoothing) procedure which eliminates roughness.
* Primer consisting of epoxy-ureic paint, applied at a thickness of 5 microns on both surfaces.>
* Baked polyester powder coating, (baked at 180-200 degrees C for 18-20 minutes) with an average thickness of 80 microns.

Windows are factory glazed with obscure or clear 1/4" wire glass. Lites have a minimum of 24 gauge wire with a maximum mesh size of one square inch as per Underwriters Laboratories requirements. Individual lites of glass shall not exceed a daylite dimension of 895 square inches each. Glass complies with ANSI Z97.l and ASTM C1036.

Frame are formed from 20 gauge steel sections, with corners which are mechanically assembled and reinforced. Sash members are 20 gauge formed sections which are coped and assembled. Corner joints are fully scaled to prevent leakage. Horizontal muntins, when required, consist of two sections of 20 gauge forming an "H" Section. Approved 1/4" wire glass are held in 3/4" uniform edge bite.

Lower sliding panel are furnished with standard pull handles and sweep lock at meeting rail. A fusible link assembly is attached directly to the front balancers and functions as the self-closing mechanism.

The Window Man sets all window frames in a level, plumb and square condition without distortion. Units are promptly anchored, flashed and caulked in accordance with good window installation practice.
