After almost a year of development and consultation with architects and other building professionals, Walker has arrived at two designs crafted specifically to meet the market’s needs. The new patterns, 226 and 227, are acid-etched on the first surface of the glass. They are available on regular AviProtek® bird friendly glass, or on AviProtek® E with a Solarban® low-e coating from Vitro Architectural Glass.
Patterns 226 and 227 are an elegant solution to architects’ and glaziers’ needs for bird friendly glazing that is attractive, effective, efficient and easy to install. The designs comprise scattered patterns of 5mm squares. Both are non-linear and multi-directional, eliminating the need for pattern alignment. With markers covering less than 1% of the glass, they offer clear sightlines wherever the glass is installed. There’s no need to choose between views and bird safety!
Both designs satisfy the widely used 2×4 rule for bird deterrence, which stipulates that spaces between pattern markers must be no more than 2” tall or 4” wide. In addition, 226 meets the stricter imperatives of the 2×2 rule which stipulates that spaces between markers be no more than 2” in either direction.
The patterns have a Threat Factor of 25 from the American Bird Conservancy and a 95% avoidance rate based on field experiments by Dr. Klem.
Walker’s Director of Products and Business Development, Marc Deschamps, explains, “We have created these new non-directional pattern options to facilitate the fabrication process, improve cutting optimization and eliminate installation challenges, thereby reducing the overall glazing cost. We also like the fact that the patterns cater to prescriptive requirements such as the Bird Friendly Design Guide recently published by the National Glass Association, and the Canadian CSA standard published in 2019. They also meet a vast range of legislative requirements such as Local Law 15 in New York city and the Toronto Green Standard.”
Both patterns are available now. Ask your Walker Glass representative for samples, or request them on our website here.
