July 23, 2009 – Kawneer Company, Inc., has introduced its new AA 3350 ISOPORT Window, designed to enhance the views and energy efficiency of any commercial or institutional application.

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.


Architects and glazing contractors are asked to deliver buildings with unmatched performance and unrivalled results. 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 one-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 at the meeting rails and a push-button feature on sweep locks helps increase safety by preventing windows from being opened accidentally or unintentionally. In addition, an integrated locking system automatically secures the operable sash when closed, preventing upper sash drift on double-hung windows. It 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.

For enhanced quality control and reduced customer labour 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. 

To provide superior esthetics for any project, the window’s integrated extruded lift rails eliminate the need for surface-applied hardware, making sight lines sleek and appealing. Muntin grids enclosed in one-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 one-inch infills.

Finish options include anodized, fluoropolymer and solvent-free powder coat painted in a variety of colours. A dual-colour finish option is also available, providing the flexibility to vary interior and exterior finishes and reduce overall system cost.
