LumiBird Protect®
Visible to birds, invisible to you
The invisibility that protects
In the design of modern buildings, transparency and natural light are essential elements for the comfort of those who live in them. However, large glazed openings present a security challenge. LumiAlarm® was created to resolve this dilemma, integrating cutting-edge technology into the very fabric of the material, without the human eye being able to detect it.
The Optical Illusion and Silent Mortality
Birds are unable to recognise glass as a physical barrier. They collide for two main reasons:
-
Reflection: The glass reflects the sky or nearby vegetation, creating the illusion of a clear path or shelter.
-
Transparency: In the case of building corners, glass balconies, or façades that allow a view of plants inside, birds attempt to fly through the material to reach what they see on the other side. Preliminary data from SPEA in Portugal indicate that around 64% of collisions result in immediate death, with migratory species (such as the spotted flycatcher and the warbler) being the most vulnerable when crossing urban areas with mirrored façades.
Reflective Dot Technology (LumiBird Protect)
Solutions such as LumiBird Protect® solve this problem by breaking the continuity of reflection and transparency.
-
Visual Contrast: The small three-dimensional reflective dots create “visual noise” that signals the presence of an obstacle to the bird.
-
Dynamic Glint Effect: As they catch the light at different angles, these points shine and sparkle. This movement of light is detected by birds’ visual systems (which are highly sensitive to movement and brightness), allowing them to change course in time.
-
2x2 or 2x4 Rule: Effectiveness depends on spacing. These solutions usually follow international standards that ensure the mesh is dense enough to prevent birds from attempting to fly through the gaps.
A balance between aesthetics and conservation
One of the greatest advantages of this type of glass is its minimal impact on architecture and human comfort:
-
Selective Visibility: Whilst birds easily detect the dots due to their superior vision, to the human eye, at a short distance (generally from 3 metres), these elements become almost imperceptible, preserving transparency and natural light.
-
Sustainability: The availability of bird-deterrent treated glass is a competitive advantage in projects requiring environmental certification or located near wooded areas and watercourses, where the risk of collision is significantly higher.
