The Series 4500 Curtain Wall Lets You Put More Money in Your Pocket Without Sacrificing Performance

Curtain Wall 4500

In a competitive marketplace, you need high-performance glazing systems that will help you save money and speed up installations. The Series 4500 Curtain Wall does just that.

The Series 4500 Curtain Wall features pressure-relieved horizontals with a patented UNIflash™ system that literally sweeps infiltrated water to the exterior. The UNIflash™ system eliminates the need to install vinyl flashing, which reduces labor costs and saves you time in the field.

Exterior and interior members are internally joined with an injection-molded thermoplastic connector, providing total thermal isolation for superior thermal performance. The unique thermoplastic connector has been tested in accelerated weathering conditions to ensure strength and durability. The Series 4500 features either stick or panel type erection with no exposed joint fasteners. Available as captured glazed or two-sided structural silicone glazed; this zone-dammed, pressure equalized system delivers exceptional performance and value.
