Silk-screened ceramic frit patterns on glass can reduce bird collisions with windows as they are always visible, even with strong reflections. GlasPro’s frit pattern glass is a long-lasting solution that blends bird-friendly function with performance and aesthetics. This cost-effective glass can reduce the transmission of light and heat while providing design detail on a building.
The Bird Safe Frit Pattern includes options with white ceramic dots covering 20 percent of the glass or 1/8” lines on the outermost (1st) surface of the glass. The line and dot patterns comply with the bird-friendly 2 x 4 rule.
The 2×4 rule describes the distance between elements making up a pattern applied to windows for the purpose of preventing bird strikes. To be effective, the pattern must uniformly cover the entire window and consist of elements of any shape (lines, dots, other geometric figures, etc.) separated by no more than 5 cm (2 inches) if oriented in horizontal rows, or by 10 cm (4 inches) if oriented in vertical columns. These patterns reduce bird-window collisions when applied to the outer surface (Surface #1) of reflective panes. Greater spacing between pattern elements increases the risk of a strike and casualties.
