System 4500 Tilt-turn Architectural Windows

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