United States Aluminum: Storefront: Series 400 Center Glazed Storefront

Series OST451 and OST451 SSG Thermal Storefront System

The Series OST451 Thermal Storefront System is engineered for optimal thermal performance and California Title 24 compliance. Offset glazing produces a flush appearance, while a slim 2" face trim and 4-1/2" depth offers a material cost advantage. The OST451 Storefront is a straight cut and stack system. No notching is required, which expedites installation and reduces labor.

Additional features include injection molded water deflectors, a continuous head and sill, and a top-load EPDM gasket that permits interior or exterior glazing. The available OST451 SSG model provides uninterrupted horizontal glass spans for a streamlined aesthetic.
