Series 4250 & 4250T Curtain Walls are a stick-erected, interior-glazed curtain walls utilizing a pocket set design and E.P.D.M. compression glazing gaskets. The system features the Poly-Aluminizer™ thermal break technology. It was especially engineered to satisfy the increasing demands for energy conservation.
