FAQ

Common questions about bird strike prevention film

How does Bird Divert film reduce bird collisions? +

Bird Divert uses a proprietary UV-absorbing and reflecting dot matrix pattern that is completely invisible to the human eye but appears as a black or violet warning signal to birds. Birds naturally avoid the pattern, reducing their tendency to fly directly into glass surfaces. The product achieves a threat level rating of 18 — the highest in the industry — as recognized by the American Bird Conservancy.

Does Bird Divert obstruct views or affect natural light? +

No. Bird Divert maintains 98% visible light transmission (VLT), which means your views and natural light remain virtually unchanged. The UV dot matrix pattern is invisible to the human eye under normal conditions, so building occupants and visitors will notice no visual difference. The film is designed to be a passive, invisible solution for both people and the built environment.

Is Bird Divert approved by bird conservation organizations? +

Yes. Bird Divert is the only window film product to achieve a threat level of 18 as recognized by the American Bird Conservancy. It is also endorsed by the National Audubon Society and is the leading bird-friendly glazing solution recommended for commercial properties. These endorsements reflect its proven effectiveness compared to other products on the market.

What is LEED Pilot 55 and does Bird Divert qualify? +

LEED Pilot Credit 55 is a certification credit under the USGBC's Leadership in Energy and Environmental Design program that rewards buildings for implementing bird-friendly design strategies. Bird Divert is one of the few products that qualifies commercial buildings for this credit, making it a smart choice for property owners and developers pursuing LEED certification or looking to strengthen their sustainability profile.

Is Bird Divert required by any local building codes in Philadelphia? +

Philadelphia and surrounding municipalities are increasingly adopting bird-friendly building regulations, particularly for new construction and major renovations involving significant glazed facades. Our team can advise you on current local requirements and help you select and install a compliant bird-friendly glazing solution. Getting ahead of these regulations is both responsible and cost-effective.

Where on a building is Bird Divert typically installed? +

Bird Divert is applied to the exterior surface of glass — no interior access is required. It is most effective on large, clear glazed surfaces such as curtain walls, floor-to-ceiling windows, atrium glass, and glass facades near green spaces, flight paths, or bodies of water. Our team can assess your building and identify the areas of highest collision risk for targeted installation.
