Guardian Bird1st™ Etch
Guardian Bird1st™ Etch
Guardian Bird1st™ Etch glass helps to prevent birds from colliding with buildings – by featuring striking and highly visible acid-etched patterns. With a choice of four distinct patterns the glass also offers enhanced design flexibility on façades and curtain walls.
Looks good, does good
Glass lends itself to sophisticated design, and is a timeless, integral component of architecture. Yet while humans use environmental cues to identify glass as a barrier, there is growing realization birds cannot. Up to a billion are estimated to die each year in collisions.* GuardianBird1st Etch glass visually signals an impending barrier to birds, helping to reduce this.

Counteracting collisions
Guardian Bird1st Etch glass features a choice of attractive acid-etched designs that help to warn and deter birds. To further defend birds, Bird1st also adheres to the 2" x 4"** rule accounting for different bird sizes and species. Helping to gain an 'Acceptable' Avoidance Index Score from American Bird Conservancy. **2″ x 4″ rule: Two inches or less of horizontal space or four inches or less of vertical space between etch markings.
Helps with performance
When paired with SunGuard® low-E coatings, Guardian Bird1st™ Etch also offers strong energy performance. It could also help you meet LEED Pilot Credit 55 and contribute to Toronto Green Standard Bird Collision Deterrence values.
