How much does commercial glass cost?

Commercial glass pricing varies significantly based on the type of glass and its performance specifications. Standard tempered glass — the most common choice for interior partitions and basic commercial windows — runs approximately $8 to $16 per square foot. Insulated glass units (IGUs) with two panes and an argon-filled cavity range from $15 to $35 or more per square foot depending on the low-e coating, spacer system, and glass thickness. Laminated safety glass adds another layer of cost due to the interlayer. Structural or specialty glazing — such as spider-fit glass facades, electrochromic panels, or fire-rated glass — can reach $50 to $150 or more per square foot. These figures cover the glass unit only; aluminum framing, structural silicone, setting blocks, installation labor, crane or lift equipment, and permitting are all additional costs that can double or triple the material-only price on a large project.
