How much do storefront windows cost?

Commercial storefront window installations generally average between $700 and $3,000 per window panel, which translates to roughly $30 to $60 per square foot of glass area. The wide variance in pricing is driven by several customizable architectural elements. The choice of aluminum frame profile, including thermal-break configurations designed to minimize heat transfer, plays a massive role in the initial material cost. Furthermore, the type of glass required heavily impacts the total, with options ranging from standard tempered safety glass to laminated impact glass, insulated double-paned units, or specialized low-emissivity (Low-E) energy-efficient glass. Finally, complex structural installations, such as high-span ground floors, hard-to-access perimeters, or projects requiring structural silicone glazing and heavy crane machinery, will noticeably push installation costs higher.
