The company puure.vision carries out reconstructions of original historical steel windows and their conversion into thermally insulated windows.

The original windows are professionally refurbished, i.e. dismantled from the building and repaired in the workshop - stripped of the original paint, repaired by metalwork, sandblasted, provided with an anti-corrosion zinc layer and the missing and damaged fittings are replaced. The original frame is supplemented with a thermal bridge break and the window is fitted with insulating double glazing. The steel industrial window refurbished in this way has a total heat transfer coefficient Uw of approximately 1.46 W/m2K.

This technologically and time-consuming repair is suitable for steel windows in historically valuable buildings, breweries, traditional historical industrial buildings, etc.
