New StormWall® XL Hurricane-Resistant Curtain Wall from CRL-U.S. Aluminum

High–Performance Curtain Wall Provides Exceptional Protection Against High Winds, Airborne Debris, and Water Infiltration

CRL-U.S. Aluminum—a leading manufacturer and supplier of architectural glazing systems–has introduced its StormWall® XL Hurricane–Resistant Curtain Wall.

The curtain wall is engineered to provide steadfast protection against severe weather while meeting stringent building code requirements.

It is NFRC–rated, Miami–Dade Certified (NOA), has Florida Product Approval, and is fully tested to ASTM and TAS Standards. The system will premiere at GlassBuild America this October in the CRL-U.S. Aluminum booth (#1528).



The StormWall® XL Curtain Wall measures 2-1/2" x 7-1/2", and is glazed with 1-5/16" insulating laminated glass. It is thermally improved using a continuous thermal spacer that is interlocked within the horizontal and vertical pressure bars.

With U–factors as low as 0.38, the system easily satisfies the Florida Building Code Fifth Edition (2014) Energy Conservation requirement. The system offers shear block assembly with no exposed fasteners for improved aesthetics and installation flexibility.

Additional performance features include:

• Large and Small Missile Impact and Cycling
• Design Pressures: Up to +100/-100 PSF
• 15 PSF Static Water Resistance
• Front Set/Exterior Glazed
• Dry or Wet Glazed
• Structural Silicone Glazed Option (Two-Sided)
• Twin Span Capability

“Our engineering experience gives us the ability to develop innovative systems that meet unique regional requirements,” said Gerald Hendrick, president of U.S. Aluminum. “StormWall® XL presents a credentialed, impact–resistant glazing solution for coastal communities that completes a comprehensive product offering. This allows us to not only compete, but also lead in specialized markets across the nation.”

StormWall® XL Curtain Wall can be integrated with CRL-U.S. Aluminum hurricane-resistant windows and doors to provide a complete building façade solution. For more information, call (800) 421-6144 ext. 5305, or email usalum@crlaurence.com.
