United States Aluminum: Curtain Wall: Series 4500 Curtain Wall

Series 4500 Curtain Wall

The series 4500 & 4500SG Curtain Wall features pressure-relieved horizontals with a unique, integral UNIflash™ system to literally sweep infiltrated water to the exterior. UNIflash™ eliminates the secondary operation of installing rigid vinyl internal flashing in horizontals as required by similar systems. Exterior and interior members are internally joined by non-conductive injection-molded thermoplastic connectors providing total thermal insulation which allows superior thermal performance. Two-tone colors can be achieved by specifying different finishes for exterior face members and interior mullions. The system features either stick or panel type erection with no exposed joint fasteners. Series 4500SG is a stick- or panel-erected system combining the horizontal members with structural silicone-glazed vertical mullions.
