Bird-Friendly Glass Treatment
Exterior marker patterns that make glass visible to birds while staying almost invisible from inside.
How it works
Birds cannot see glass. Markers give them something to read.
Birds collide with glass because reflected sky and vegetation look like open flight paths. The fix is a visual marker pattern that breaks up that reflection at a spacing tight enough that a bird will not attempt to fly through the gap.
Two things determine whether a treatment actually works. First, position: markers belong on the first surface, meaning the outside face of the glass, because a pattern behind a reflective outer surface disappears. Second, spacing. Guidance has tightened over the years from the old two-by-four inch rule toward a two-by-two inch approach, and the Canadian standard CSA A460 sets out marker size, spacing and the height of glazing that should be treated.
Municipal and rating-system requirements add their own numbers, including the Toronto Green Standard and the LEED bird collision deterrence pilot credit. We install to the standard your project is being assessed against, so tell us which one applies before we quote.
-
First surfaceMarkers applied outside, where the bird actually sees them.
-
Tight spacingModern guidance moves toward roughly 50 mm spacing in both directions.
-
Treated heightStandards define how far up a facade requires treatment.
-
View retainedPatterns are designed to read to birds while barely registering inside.
Where it belongs
Typical applications
Glazing that reflects sky or vegetation, or that birds can see through.
-
New commercial builds
Projects targeting a green standard or municipal bird-safe requirement.
-
Glass near vegetation
Elevations facing trees, green roofs and landscaped courtyards.
-
Glazed link corridors
See-through walkways and corners that read as open flight paths.
-
Known collision hotspots
Retrofits at facades with a documented strike history.
-
Rating-system projects
Buildings pursuing LEED pilot credit or municipal green standards.
-
Homes and low buildings
Most collisions happen at low-rise and residential scale, not towers.
Specification
What to specify
Bird-friendly is a measurable requirement, not an aesthetic preference. Confirm which standard governs your project and we will install to its numbers.
