Versatile Window for Commercial and Institutional Applications Increases Thermal Performance, Safety and Security

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.
