Cost Considerations in Specifying Vitro Architectural Glass

Low-E Glass,
Choosing Glass Products,
Understanding Performance,
Specifying Glass

To make more informed decisions in the evaluation, selection and specification of architectural glass products, Vitro Architectural Glass (formerly PPG glass) recommends using an installed systems cost approach. The pie chart below indicates the approximate cost percentage of fabricated glass relative to a typical installed curtain wall total cost. The table, “Fabricated Glass Options,” indicates the relatively minor cost impact of selecting various Solarban® solar control low-e coated glasses by Vitro glass on the overall installed cost.

Fabricated Glass Cost Considerations

Architectural designs can be a significant driver of glass cost. Total fabricated glass costs can be significantly impacted by unit designs (square footage and aspect ratio), unit quantities (total units and number of unique sizes) and glass fabrication yield losses due to cutting, tempering, heat-strengthening and laminating. Special considerations such as frit or etched glass, spandrel glass, non-rectangular or oversized units and glass thickness can also substantially impact fabricated glass costs.

Glass Selection Conclusions

Selecting the proper high-performance Solarban® glass by Vitro Glass product for your project can provide improved solar and thermal performance, increased occupant comfort, reduced HVAC investment and enable a broad spectrum of design aesthetics.

The total installed cost impact of upgrading to various Solarban® glass coatings—whether on Clear, Starphire Ultra-Clear®, or tinted glasses by Vitro Glass—is minimal and represents, on a standard project, typically a 5-7% additional cost impact.
