Two items from the commercial glazing world this month, with what they mean for owners, architects, and contractors in Houston. The summaries are ours; follow the links for the full pieces.
Bird-friendly glass is moving into the codes
The National Glass Association’s 2026 advocacy brief, Saving Birds with Effective Glass Solutions, explains why clear and reflective glass causes bird collisions. Birds see reflected trees and sky, or a clear path through the glass, as open space. Glass with visible markers or patterns at the right spacing interrupts those reflections and reduces collisions.
The brief notes that NGA’s best-practice guide for bird-friendly glazing is referenced in language approved for the 2027 International Green Construction Code and ASHRAE 189.1-2026. Cities are adopting their own rules as well: Palo Alto’s bird-friendly design ordinance took effect in May 2026 and requires treatment on larger areas of glass.
Why it matters here: Houston has no general bird-safe glazing requirement today, but projects that pursue green building certifications, institutional and campus work, and owners with sustainability goals are starting to specify it. Bird-friendly glass is available as fritted, etched, or patterned glass and as insulated units for curtain wall and storefront systems. It affects appearance, performance data, and lead time, so it is best decided at design development rather than at bid.
What bird-friendly glass looks like
Most bird-friendly products work by putting a visible pattern on or in the glass, spaced closely enough that birds read the surface as a barrier:
- Ceramic frit (dots, lines, or custom patterns) fired onto the glass during tempering.
- Acid-etched or sandblasted patterns on one surface.
- Patterned interlayers or coatings inside insulated or laminated units, where the pattern is protected from weather and cleaning.
- Applied exterior films, often used to retrofit existing glass where collisions are already a problem.
When comparing options, ask for the product’s bird collision rating where one is published, how the pattern affects visible light and solar performance, and whether the treatment is on the exterior surface, where it works best for reflections, or inside the unit.
Award-winning commercial glazing
Canadian Architect covers the winners of the Guardian Glass 2026 Commercial Project Awards, which recognize projects where the glass and its fabrication are central to the design.
Why it matters here: award projects are a useful reference when an owner asks what is possible with large panels, coatings, and complex fabrication. Our commercial glazing services cover curtain wall, storefront, entrances, and specialty fabrication.
Planning a project?
If bird-friendly glazing or a specialty glass is under consideration, send us the drawings early. We can review the specification and the glazing details before the bid.
