4BIRD is a permanent marking on fully tempered safety glass with tested designs and harmonised colours. Being tempered, it allows for use in any construction application and in combination with laminated safety glass it also provides safety against falling. Achieving up maximum transparency – up to 94 % of the glass surface can remain transparent, but still retaining their maximum effectiveness. 4BIRD designs fulfill Category A and are therefore “very effective”. Discreet and effective, permanent and economical.


4BIRD is a  bird friendly solution. Every year, hundreds of millions of birds die in Europe as a result of collision with transparent glass. New test requirements have caused us – through systemisation of special colours and patterns – to develop the product 4BIRD. ECKELT designed the internationally protected 4BIRD designs for maximum transparency. These have been coordinated with the Vienna Environmental Agency (WUA) as well
