Walker Glass will introduce new bird-friendly glass design options to help meet increasing requirements for bird friendly building products in cities throughout North America. During GlassBuild America, the company is launching three new dot patterns—219, 220 and 221—with visual markers on surface No. 1. They are part of the AviProtek product line and are typically used for guardrails, rain screens and insulated glass units, which usually feature a third-surface low-E glass. Booth #807
