For the first time, a “laser upgrade” of façades, balustrades or windows in their installed state is possible by using mobile laser technology. Thermal insulation and other functional layers can be provided with new functions and even uncoated glass surfaces can be upgraded. This is made possible by laser-supported functional layer modifications and, alternatively, laser transfer printing.

By using special mobile laser equipment developed for outdoor use, the “laser upgrade” can still be carried out on buildings at a later date. This extends the service life of architectural glass products, as they do not have to be replaced due to new requirements for the building envelope or due to missing comfort functionalities.

Upgrading or legally required functions such as improving mobile phone reception or adding structures to minimize bird strike are examples of broad possibilities for laser doubling. This is the first time a sustainable solution for the use of architectural glass beyond a maximum or extended lifetime is presented.
