From raw material acceptance to profile production, from ready-to-wear manufacturing to double glazing production, complete and uninterrupted quality control at all stages of production ensures continuous safety. The impact of external factors such as sunlight, rain, humidity, seasonal temperature differences on the PVC profiles and the durability of the profiles are tested in Kompen's laboratory environment with high technology devices.

With the aging test, we observe the change of our profiles in years, and we make adjustments to the production stages according to change benchmarking results.
