Guardian Bird1st™ Etch glass features translucent acid-etched patterns designed to deter birds from collision. Achieve a wide array of looks while improving bird safety and meeting energy performance requirements.
Bird1st Etch glass products are available in six patterns – and in large sizes that make Guardian’s bird-friendly glass bigger and more beautiful than ever. Choose from directional, non-directional and randomized patterns as you design bird-friendly facades and curtain walls. Explore options below.
The acid-etched patterns of Guardian Bird1st Etch glass are strategically spaced to provide an effective deterrent for birds of different sizes and species. Based on guidance from the American Bird Conservancy, Bird1st Etch patterns spaced at least 2" x 4" or 2" x 2" apart to significantly reduce collisions. Learn more about the science.
Paired with SunGuard™ low-E coatings, Guardian Bird1st Etch glass also delivers on energy performance. Bird1st products may help you meet LEED Pilot Credit 55 and contribute to Toronto Green Standard Bird Collision Deterrence values.
