SMI-175 Impact system for 9/16”

The SMI-175 is a heavy walled, hurricane resistant impact window wall system capable of achieving very high wind load demands. Its thick walled construction allows Aldora to achieve the high loads with large glass panels and minimal mullion interruption. With just 4 extrusions, the simplicity in design of the system allows it to be easily fabricated. Its screw spline assembly creates the ability to factory pre-glaze storefront or window panels.. The SMI – 175 is a wet seal, non-weep system designed to not let water penetrate.
