Window Slavona PROGRESSION GRP

The company Slavona will start the production of a significantly innovated window PROGRESSION at the beginning of 2020. The most important change is the use of a different material for the production of the external window frame.

Unlike the original design, where the external frame is made of a thermowood profile combined with a thermal insulation material CompacFoam, the PROGRESSION window uses a special composite profile with insulation filling. The window will therefore be not only more energy-efficient but also practically maintenance-free. Another benefit will be greater variability when integrating the window into the building – the builder can decide whether to completely hide the frame under the facade or leave a certain part visible.
