Architectural Decorative Glass


Volare is a barely visible bird friendly glass solution offered by Pulp Studio. The subtlety of the visual markers is an appealing proposition as a bird safe glass. Markers on surface #1 that are visible to birds but hardly visible to human eyes.
This transparent product can be used in insulated units and can be
combined with a low-e glass on position 3.

Bird collisions with building glass facades occur all across North America and is the major cause of bird mortality, claiming the lives of millions of birds each year. While bird mortality caused by wind turbine strikes, vehicle road-kills and domestic cats are important, collisions with buildings tops the list.

The level of awareness and the magnitude of the problem is such that the need to make buildings much more bird friendly has become an important design consideration.

An increasing number of states, counties, provinces and municipalities in Canada and United States have adopted voluntary or mandatory bird friendly glazing guidelines. Ultimately, the need to use bird friendly glazing materials is based on risk factors specific to the building and its location.

More specifically, the factors to consider are:

Risk factors directly associated with glass are:

Bird casualties are documented at panes of all sizes in single and multilevel residential and commercial buildings, throughout the day and seasons of the year, and during all types of weather conditions.

Here are specific high risk glass applications that present a threat to birds:

In designing the best glazing system while reducing the risk of bird collisions, architects must consider both functional and performance properties.

Bird Friendly Properties

Birds have many more sensors and color filters than humans but even with their astounding abilities, countless research and experiments indicate they are not capable of seeing clear and reflective glass but rather what is reflected by the glass pane.

Studies further indicate that the bird’s midbrain is not as sensitive to signals or visual markers while in motion but it is quite sensitive to contrast.

With that in mind and based on experiments conducted by the American Bird Conservancy and Professor Daniel Klem as well as real life applications, bird friendly properties must beable to respond to the following:

Functional and Solar Properties

The ultimate bird friendly solution should deter collisions without having to compromise significantly on other properties that are otherwise very critical. They include:
