Goldray's Bird-Friendly Glass is a durable, pigmented glass enamel permanently fused to the first surface of a lite for use on the exterior of a building to deter birds from flying into the structure. Also referred to as First Surface Ceramic Frit, this product is available in many solid colors and patterns and has an exceptional chemical, UV and weather-resistant properties, which enable it to withstand the elements in exterior applications.
First Surface Ceramic Frit can be applied to glass for a cost-effective, low-maintenance solution to design needs as well as acting as a bird collision deterrence feature. All Bird-Friendly glass is subjected to the tempering process, where the ceramic paint is fused directly to the glass. This creates a highly durable, long-lasting, and abrasion-resistant product, that works for both interior and exterior applications.
Studies have shown that patterns covering as little as 5% of the total glass surface can deter 90% of bird strikes under experimental conditions. Most birds will not attempt to fly through horizontal spaces less than 2" high nor through vertical spaces 4" wide or less. Goldray recommends that patterns on the glass are designed to follow the 2" x 4" rule.
A newer study suggests using color to aid in avoiding bird strikes on glass. Red hues are statistically greater at deterring collisions than any other color. The science behind this is that red is a common color among predators in the animal kingdom. Instinctually birds will avoid flying headlong into a situation that they perceive to be dangerous. With that being said, using a pattern with the 2"x4" rule and a visible frit offers the greatest possibility of avoidance.
