Product Solution
South Star, through its Glaspedia bird safe glass portfolio, offers advanced solutions that integrate safety, durability, and design flexibility:
-
1. AvianSafe Grey Dot 01
A ceramic frit dot pattern fired onto the glass surface, providing high-contrast visibility while maintaining daylight transmission. The frit is permanently bonded, ensuring resistance to UV, abrasion, and weathering, and complies with ASTM and EN standards.
TF = 25 -
2. AvianSafe BIPV 40
A building-integrated photovoltaic solution that combines renewable energy generation with bird-safe grading. CdTe thin-film cell patterns deter collisions while supporting vision transparency, energy efficiency and bird-friendly compliance.
TF = 30 -
3. Laminated Glass with Bird-Safe Interlayers
Incorporating Kuraray BirdSecure™ Pro and Eastman Saflex® FlySafe™ 3D Laminate, these laminates embed deterrent patterns within the glass, offering permanent bird protection alongside acoustic insulation, impact resistance, and UV filtering.
TF from 10 to 29 -
4. Digitally Printed Glass
Using durable Ferro S1de One Series ceramic inks, South Star offers white lines or blue dot patterns fused into the glass, delivering long-term performance and design versatility.
TF from 17 to 21

Conclusion
Frequently Asked Questions
QWhat is the Threat Factor (TF) and why does it matter for bird-safe glass?
The Threat Factor (TF) is a standardized rating used to measure how dangerous a glass product is to birds. A lower TF indicates fewer bird collision risks. Products with a TF below 30 are generally considered acceptable for bird-safe building certification, while those below 10 offer the highest level of protection.
QWhat is the difference between AvianSafe Grey Dot 01 and AvianSafe BIPV 40?
AvianSafe Grey Dot 01 uses a ceramic frit dot pattern fired onto the glass to create high-contrast visual markers for birds, with a TF of 25. AvianSafe BIPV 40 integrates CdTe photovoltaic cells to combine solar energy generation with bird deterrence, achieving a TF of 20. BIPV 40 also supports renewable energy goals for green building projects.
QAre bird-safe interlayer laminates (Trosifol / Saflex) compatible with standard laminated glass systems?
Yes. Both Kuraray BirdSecure™ Pro (Trosifol) and Eastman Saflex® FlySafe™ 3D PVB are designed to be fully compatible with standard laminated glass configurations such as 6mm/PVB/6mm. They can be applied on surface #2 or #3, and additionally provide acoustic insulation, UV filtering, and enhanced impact resistance.
QHow long is the warranty on South Star's bird-safe glass products?
All bird-safe glass products in the Glaspedia portfolio — including AvianSafe Grey Dot 01, AvianSafe BIPV 40, Trosifol Bird Secure Pro, Saflex FlySafe 3D PVB, Dip-tech Frit, and Pilkington Avisafe — come with a 10-year warranty, ensuring long-term reliability and performance.
QWhich bird-safe glass option is the most cost-effective for large curtain wall projects?
For a 3,000m² curtain wall project, AvianSafe Grey Dot 01 is the most cost-effective option at approximately HK$600/sqm, followed by Dip-tech 1st Surface Frit at ~HK$800/sqm and Trosifol Bird Secure Pro at ~HK$900/sqm. AvianSafe BIPV 40 is the premium option at ~HK$2,000/sqm, justified by its dual function as both a bird deterrent and energy-generating system.
QDo South Star's bird-safe glass products comply with international standards?
Yes. South Star's Glaspedia bird-safe glass solutions are engineered to comply with internationally recognized standards including ASTM E2947 and EN standards for bird collision deterrence. The ceramic frit patterns are permanently bonded and resistant to UV, abrasion, and weathering, ensuring long-term compliance and performance in diverse climatic conditions.
