Sustainability
Built for birds. Built for buildings.
AviProtek® is a genuine environmental solution — not a marketing claim. Acid-etching eliminates the need for applied films that degrade over time and generate waste.
No Films or Coatings
The pattern is etched permanently into the glass surface itself. No film delamination, no replacement cycles, no waste — ever.

FAQ
Frequently Asked Questions
How is AviPortek T different from other AviProtek solutions?
AviProtek® T isn’t just different, it’s more discreet. Instead of acid‑etched patterns, we use Pilkington North America high‑performance pyrolytic UV coating and create contrast that birds can see but barely noticeable for people.
Do AviProtek® T patterns meet bird-friendly design standards?
Yes, the AviProtek T stock patterns do meet the industry-recognized 2×4 rule. Patterns like the 717 are also accepted under the Canadian Standards Association’s CSA A460:19 bird-friendly building design standard. The first surface UV AviProtek T has been validated through field testing by Dr. Daniel Klem of Muhlenberg College.
On which surface can low-e coating can be use with AviProtek T?
The pyrolytic coating is on surface 1 (the exterior-facing surface) of the IGU. It can be paired with the low-e glass of the building professional choice on surface 3, providing both bird-friendly protection and energy performance in the same unit.
What applications is AviProtek® T best suited for?
AviProtek T can be use in insulated glass units but also in guardrails, linkways, and shelters where applications are a highly transparent and minimally visible bird-deterrent surface is preferred over a more visually obvious pattern.
Does AviProtek® T affect visible light transmission?
Not especially, the UV coating doesn’t reduce in a meaningful way the visible light transmittance compared to standard clear glass.

What Professionals Say
Trusted by architects and fabricators
The permanence of the etching is what sold us. We’ve specified bird-safe film solutions before and the maintenance callbacks are a liability. AviProtek® is a specification we’re confident in for the long term.
Principal Architect
Mid-rise Commercial Practice, Chicago
Our fabrication team found the handling and tempering process completely straightforward. The etching holds up through secondary processing without any special handling beyond standard acid-etch protocols.
Operations Manager
Glass Fabricator, Pacific Northwest
For our NYC project we needed a solution that met Local Law 15 requirements and could integrate with our high-performance glazing system. AviProtek® E gave us both without any compromise on thermal performance.
