Guardian Bird1st™ Etch

Guardian Bird1st™ Etch

Guardian Bird1st™ Etch glass helps prevent birds from colliding with buildings – by featuring striking and highly visible acid-etched patterns. With a choice of four distinct options, 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 that 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: Design that accomodates two inches or less of horizontal space or four inches or less of vertical space between etch markings.

Counteracting collisions

Helps with performance

When paired with SunGuard® low-E coatings, Guardian Bird1st™ Etch also offers strong energy performance, helping you meet LEED Pilot Credit 55 and contributing to Toronto Green Standard Bird Collision Deterrence values.
