Optimum Window manufactures custom steel and specialty metal windows and doors for residential, commercial, heritage, and architectural applications. Its product range includes narrow-profile steel systems, thermally broken frames, stainless steel, aluminum, fire-rated products, and custom configurations designed around the requirements of each project.
Optimum Window has manufactured custom steel windows and doors since 1985 and has developed a broad portfolio for residential, institutional, commercial, and specialty architectural projects.
Its systems are available in hot-rolled and cold-rolled steel, thermally broken steel, stainless steel, bronze alloy, and aluminum, depending on the product line. Optimum also manufactures products for specialized requirements including fire-rated, impact-rated, heritage, and other high-performance applications.
Unlike more standardized residential window lines, Optimum products are often selected where narrow sightlines, larger glazed areas, custom configurations, or specialized performance requirements are central to the design.

Optimum is particularly suited to projects where the window or door system is an important architectural feature rather than simply a standard building component.
The strength of steel allows for relatively narrow frames and larger glass areas, while Optimum’s broad product range allows designers and homeowners to address different requirements for appearance, thermal performance, heritage compatibility, and specialized building conditions.
