Kawneer’s New 1630 SS IR Curtain Wall Delivers Performance Under Pressure

news1a-june2013We recently introduced our new 1630 SS IR Curtain Wall, an impact resistant, 3" sightline curtain wall system that offers an additional line of defense against high winds, heavy rains, hurricanes and more. Having undergone rigorous testing to hurricane impact and blast mitigation standards, the 1630 SS IR Curtain Wall meets increasing design pressure requirements and can deliver larger spans. And, screw-spline architecture with both dry and wet glazing options makes the 1630 SS IR flexible as well as easy and fast to install. 

Performance and Protection 

Impact tested products, which were predominantly being applied in Florida and along the Gulf Coast, are increasingly being specified down the Eastern seaboard and in Hawaii. Mounting design pressure requirements on buildings in impact zones, larger span needs, and ease of installation requirements have necessitated the movement to a new 3" sightline. Built on the success of the flagship 1600 curtain wall platform, Kawneer’s 1630 SS IR Curtain Wall meets those needs. 

The curtain wall has been comprehensively tested to ASTM 1886 and ASTM 1996 standards, the TAS 201, 202 and 203 test protocols to meet Florida Building Code (FBC), and Miami-Dade’s Notice of Acceptance (NOA) criteria. The product has been large and small missile impact tested and meets the even more stringent Level E (Enhanced Facilities) requirements.

To offer buildings and occupants additional levels of protection, the 1630 SS IR Curtain Wall has been tested to meet stringent federal requirements as outlined by the Department of Defense (DoD) and Interagency Security Committee (ISC)/General Services Administration (GSA) as well as testing standards for blast performance as set forth in ASTM F 1642 Standard Test Method for Glazing and Glazing Systems Subject to Airblast Loading. 

In order to provide a better thermal barrier, the separation of interior and exterior metal has been increased to lower the U-factor of the system to meet more demanding energy codes. And what’s more, the 1630 SS IR Curtain Wall is available in wet (silicone) glazed and dry glazed options, both of which have been tested up to 130 psf design load.

Visual Impression

Kawneer’s 1630 SS IR Curtain Wall delivers elite impact resistance without compromising aesthetics. The 3" wide profile presents clean, uninterrupted sightlines. Different mullion depths are available to address a variety of project-specific design needs including single-span and twin-span applications. For increased flexibility, dual color options provide the opportunity to vary interior and exterior finishes. 

Ease of Installation

To reduce installation time and effort, installers can leverage their existing knowledge of our flagship 1600 curtain wall platform fabrication and installation methods. Screw-spline fabrication of the curtain wall system allows for pre-assembly in shops and the ability to be installed in ladders. Straight cuts without notching also simplify fabrication. The system’s wider 3" profile provides deeper pocket depth, which creates more clearance between the glass edge and the mullion tongue, enabling easier installation of glass. The easy-to-install screw-spline fabrication curtain wall system features an interlocking mullion design, which eliminates the time-consuming effort of applying anti-buckling clips.
