System 4500

REHAU's updated System 4500 tilt-turn architectural window design offers a high-end, multi-chambered window system engineered to exceed current window test standards. A high quality European-engineered dual sealing system forms a barrier against the elements, with an uninterrupted inner and outer compression seal around the entire window. A multi-point locking system improves overall aesthetics and provides consistency, while the multi-chambered design provides superior thermal insulation.
