More about this product

C.R. Laurence U.S. Aluminum’s Series 4500 Curtain Wall features pressure-relieved horizontals with a patented UNIflash™ System that sweeps infiltrated water to the exterior and eliminates the need to install vinyl flashing. Coupled with a pressure-bar-free design, the Series 4500 Curtain Wall can provide material savings of up to 15% to maximize value.


Exterior and interior members are internally joined with an injection-molded thermoplastic connector that provides total thermal isolation for superior thermal performance. The Series 4500 Curtain Wall delivers U-factors as low as 0.24 and has been tested for water infiltration to 20 PSF. Additional advantages include:

  • Material Savings of up to 15%
  • Faster Project Completion Times
  • Less Expensive than Conventional Pressure Bar Systems

The Series 4500 features either stick or panel type erection with no exposed joint fasteners. It’s available in captured glazed or two-sided structural silicone glazed configurations. This zone-dammed, pressure equalized system delivers exceptional performance and value.
