Combing glass with Heliatek brings several key advantages regarding the competition. First one is the performance in low light conditions. The second one is aesthetic because the product looks very nice, but on top of it, it can be partly transparent. The last one is the low-temperature dependency.

We believe the future of function and facade systems is a combination of film and concrete. Heliatek’s products are powerful and can be attached directly to the concrete facade. Without any need of cooling and ventilation systems.

Bernd TrompeterManaging Director Reckli Germany

We are pleased to have created another eco-friendly solar façade with Heliatek in Germany. The building exterior of duisport received a second skin, one that generates energy. With each new project, we gain experience in installation, and also in terms of handling. The current short installation time of just a few minutes per film is impressive.
