Bird Friendly Glass For Commercial & Residential

The Problem with Birds and Glass: 

According to the American Bird Conservancy, millions of birds die each year after collisions with glass from buildings and homes. The visibility of most birds in North America is often obstructed from reflective windows during both day-time and night-time. Most birds simply can’t see the glass well enough to distinguish shine, reflection, or deception to steer clear. In addition to endangering the life of these precious animals, birds colliding into windows can often cause damages to property resulting in paying for replacement windows and other associated costs. 

The Bird Friendly Glass Solution: 

Bird friendly glass can be created during manufacturing or post-production to help birds in flight see the glass ahead. This also helps businesses and families avoiding the glass on their property being damaged. Bird friendly glass is strategically designed to be more visible by incorporating lines, dots, or other visible patterns into the glass using glass printing techniques. Research shows that the most effective way of protecting birds is by using lines spaced two inches apart for horizontal rows or four inches apart for vertical rows. When printed correctly, bird-friendly glass is not visible to the human eye but is extremely visible to birds across North America.

Diving Deeper into 
Bird Friendly Glass:

Ceramic dots, lines or other types of “frits,” can be printed, or otherwise applied to glass surfaces. This is often done to reduce the transmission of light and heat and can also provide design detail. In some cases, frit patterns are hardly visible, but when designed according to the 2 x 4 rule (where marker spaces should not exceed 2" in height by 4" in width) patterns on glass can prevent birds from hitting your glass. This can be illustrated below.

Properties of Glass 

Glass can appear very differently depending on a number of factors, including how it is fabricated, the angle at which it is viewed, and the difference between exterior and interior light levels. 

Combinations of these factors can cause glass to look like a mirror or dark passageway, or to be completely invisible. Humans do not actually “see” most glass, but are cued by context such as mullions, roofs or doors. Birds, however, do not perceive right angles and other architectural signals as indicators of obstacles or artificial environments.

Help save birds with Bird Friendly Glass

Birds are an essential part of our everyday world. They help by pollinating plants, distributing seeds, and eating insects. Birds are also useful for pest control and pollination for agriculture and forestry. Birds are important for keeping nature in the city and add to our quality of life through their song and colorful appearance. We can help save millions of birds every year by using bird friendly glass for our windows.

”We used to have to replace our windows every couple months as a result of birds flying into them. Since working with HPGlazing, we haven’t had a single bird collision in over 1 year”
