The Impact Of Tariffs On Commercial Glass Projects

Tariffs are becoming an increasingly important consideration for contractors, architects, developers and building owners planning commercial glass projects. Curtain wall systems, storefront glass, glass entry doors and the aluminum or steel framing used to install them can all be affected by changing material costs and trade policies.

In 2026, U.S. tariff policies continue to place significant duties on certain imported steel and aluminum products and derivatives. The current rules can affect the cost of materials that are incorporated into commercial glazing systems, potentially increasing project costs and creating greater uncertainty when budgets are established.

For projects involving large quantities of aluminum framing—such as curtain walls and storefront systems—even relatively modest material-cost changes can have a meaningful impact on the overall project budget. Glass entry doors can also be affected when aluminum framing, hardware and related components are subject to increased costs.

For contractors and developers, the result can be more challenging estimating, longer lead-time considerations and the need to review material pricing closer to the time of purchase. The Associated General Contractors of America recommends that contractors carefully consider tariff provisions and their potential impact on construction contracts and material procurement.
