ATL PVB ARCHITECTURAL Bird-Safe Series

The Bird-Safe PVB series interlayer film is developed specifically to prevent bird collisions with architectural glazing, using UV-reflective dot-pattern coatings on the film surface. By integrating micro-patterned ceramic or nanoparticle-based coatings that are visible to birds but nearly transparent to human eyes, this film enhances bird safety without compromising the building’s aesthetics or natural lighting. The pattern is applied inline during film extrusion, ensuring durability, precision, and cost-effectiveness.

Specification

Product Features:

Bird Collision Prevention: Uses scientifically spaced dot patterns (~5x5 cm) to break glass reflectivity, making it visible to birds’ UV-sensitive vision.
UV-Reflective Coating: Pattern designed with UV-reflective materials (e.g., silane-modified ZnO) that birds can detect, while remaining visually unobtrusive to humans.
Long-Term Durability: Resistant to weathering, abrasion, and UV degradation. Suitable for both indoor and outdoor facades.
High Optical Transparency: Maintains building daylighting efficiency with >85% visible light transmittance.
Easy Integration: Compatible with standard lamination lines; no need for additional glass surface printing or etching.
