The innovative SR6700 Series window system from Graham Architectural Products is designed to replicate the steel windows used in many historic structures built in the early- to mid-20th century.
These windows feature an available floating vent and large openings with minimal site lines. Historic concave true muntins and applied grids add to the authentic steel window look.
This aluminum window system has played a vital role in attaining National Park Service approvals for many projects due to its ability to restore the original beauty to retrofit projects while delivering high performance.
