With us, top quality is standard.

Everything goes unto the test bench.

Everything goes onto the test bench

Before new materials and profile types are used, they are subjected to extensive internal and external testing. In particular, the heat and sound insulating properties of our profiles are verified by appropriate certification.

We also supply shot, explosion or break-in resistant roller shutters; naturally, with the required certificates.
