Aluminum uses a lot of energy in its production and is highly conductive; not at all energy efficient. If using aluminum windows, specify thermally broken frames only.

Provide improved construction tolerances and weatherstripping to limit air infiltration to 0.10 cu. ft. per min. per ft. of crack at edge of operable sash; tested by ASTM E 283, for 20% of pressure resulting from design wind loading.

Provide horizontal blind insert where indicated, between sheets of double glazing with one sheet removable for cleaning interior; coated aluminum slats, polyester cords, remote operator for tilt and raising/lowering.

2.07 INSECT SCREENS

Provide manufacturer's standard aluminum framed units for each operable sash (vent), with 18 x 14 replaceable mesh and vinyl retainer spline.

2.11 POLE OPERATOR

Manufacturer's standard unit; provide one pole and one hanger bracket for each room or space where windows require pole for operation, except provide one pole per living unit for residential construction.


PART 3 — EXECUTION

3.01 INSTALLATION/ERECTION

Preglazed Construction: To greatest extent possible, glaze window units at shop prior to installation. Comply with requirements of "Glass and Glazing" section for type of glass and glazing materials.

Delete following if not required. Possibly specify as "Miscellaneous Metal" if not supported by window units.
Coordination of Fabrication: Check actual window openings in construction work by accurate field measurements on final shop drawings. However, coordinate fabrication schedule with construction progress as directed by the Contractor to avoid delay of work. Where necessary, proceed with fabrication without field measurements, and coordinate installation tolerances to insure proper fit of window units.

Anchor Window units securely in place, with permanent separations to prevent electrolytic corrosion. Seal entire perimeter of each unit as shown; comply with applicable requirements of "Joint Sealer" section.

Adjust and lubricate operating sash and hardware for proper operation. Clean aluminum surfaces promptly after installation; do not damage protective coating; repair minor damage of finish. Clean glass promptly after installation.

Additional Material Supplied to Owner: Supply to owner insulating glass lites identical to those installed as follows:

Add required extra lites; if none, delete.
