General: Series 900 windows (Thermal Barrier Single-slide) are designed to
meet or exceed AAMA performance requirements both thermally and structurally.
This window carries a thermal rating, and the AAMA/NWWDA 101/I.S.2-97
structural rating of HS C-65.
Finish: The standard finishes are acrylic white, black, bronze, green or beige,
electrostatically applied and baked-on acrylic finish. Other architect specified
finishes may be available at an additional cost.
Material: The aluminum used is of commercial quality 6063-T5 alloy, with a
minimum ultimate tensile strength of 22,000 psi, free from defects impairing
strength and durability. Series 900 windows feature standard wall tolerances
as defined in the Architectural Aluminum Manufacturers Association Master
Specifications for Aluminum Windows HS C-65. They utilize a urethane thermal
barrier material as a separator in conjunction with rigid vinyl adaptors to
complete the thermal barrier separation.
Glazing: Operable sash glazing is a heavy, vinyl wrap-around “marine”
type, and dead panel is tape/bead glazed to satisfy a good glazing condition
between metal and glass. The primary glazing is for 7/8” double glazed to
assure the best thermal barrier insulation.
Spacer: Quanex's Super Spacer® contains NO-Metal and is one of the most
thermatically efficient IG spacers available today. Super Spacer® reduces seal-
ant stress while improving heat flow resistance, glass surface temperature,
condensation resistance and sound absorption. Super Spacer® is the only poly-
mer foam, NO-Metal warm edge spacer.
Weatherstripping: The weather seals provided are of polypropylene pile
with fin seal. Fin seal type weather seal is used in combination with bulb or
rigid vinyl to achieve maximum weather tightness.
Hardware: Inside rolling panels are equipped with spring type locks that
strike side jambs for positive automatic locking. Optional “oversized” handles
are available. The vent sash rolls on tandem stainless steel, self-lubricating
axles with bronze wheels, held in place by a two-position, rust-proof housing.
Frame/Sash: Master frames and sashes have dual-screwed overlap
joints. Master frame head, sill and jambs are designed to receive stacking con-
dition by way of thermal break mullions. (Note: All metal-to-metal joints must be
back sealed in the field if the windows are field mulled.) Master frame sill is of
“Tank Sill” design for high water performance rating.
Screens: The screen channel design in the Master frame allows the use of a
half-screen. 18 x 16 fiberglass mesh is attached to the screen box frame by a
spline lock in the screen channel. WARNING: Insect screens are intended to
provide reasonable insect control, and are not intended to provide for the reten-
tion of objects or persons from the interior.
