Alcoa (NYSE:AA) announced
today that its Kawneer business, the leading manufacturer of architectural aluminum
building products and systems for commercial construction, introduced its new
AA®3350 ISOPORT® Window, designed to enhance the views and energy efficiency
of commercial and institutional applications. Available in single-hung, double-hung
or fixed with an innovative polyamide thermal break design and factory glazing,
the AA®3350 ISOPORT® Window is highly versatile, leading the way in
thermal performance at a competitive price.
Kawneer’s AA®3350 ISOPORT® Window combines distinctive features,
superior aesthetics and simplified fabrication and installation to provide architects
and glaziers with a product that meets their needs. The unique shape of the
polyamide thermal break enhances the performance of the window by maintaining
the continuity of the thermal break throughout the window frame and sash. Adding
to the energy efficiency of the window is 1-inch insulating or laminated glass,
which provides high thermal performance and enhances STC and OITC (sound resistance)
performance. AA®3350 ISOPORT® Window features powder coated die-cast
sweep locks and keepers for maximum security and a push-button feature on sweep
locks prevents windows from being opened accidentally. In addition, an integrated
locking system automatically secures the operable sash when closed, preventing
upper sash drift on double-hung windows.
The AA®3350 ISOPORT® Window has been tested to meet North American
performance standards, including thermal transmittance, condensation resistance,
condensation temperature index and sound transmission, and multiple sill heights
are available to meet both 10 pound (CW) and 15 pound (AW) psf water performance
requirements.
Factory Assembled and Glazed
For enhanced quality control and reduced customer labor costs at the job site,
AA®3350 ISOPORT® Window is factory assembled and glazed. Factory silicone
glazing improves window quality and performance while eliminating the time investment
and costs of field glazing. Removable stops ensure easy re-glazing with no disassembly
required. Multiple installation options, designed to accommodate a variety of
installation methods, include a frame flange/nailing fin, strap anchors and
receptor system.
Superior Aesthetics
To provide superior aesthetics to any project, the AA®3350 ISOPORT®
Window’s integrated extruded lift rails eliminate the need for surface-applied
hardware, making sight lines sleek and appealing. Muntin grids enclosed in 1-inch
insulating glass provide a traditional design option that is virtually maintenance-free.
The 3-1/2-inch frame depth results in a narrower interior to exterior transition
and the window also provides the minimum overall window depth to achieve structural
performance and accommodate 1-inch infills.
Finish options for AA®3350 ISOPORT® Window include anodized, fluorpolymer
and solvent-free powder coat painted in a variety of colors. A dual color finish
option is also available providing the flexibility to vary interior and exterior
finishes and reduce overall system cost.
