The standard sealed unit is 3-pane with a warm distance frame, low-emission glass and an argon filling in the void between panes.


Pine wood has a light colour and is an excellent base for water-based azure varnishes, which allow you to expose the natural grain. We colour the frames in fourteen different colours - from transparent and white, through light yellow and various shades of brown, to very dark colours. Colours are available in two price groups. Available as standard: colourless 666, white 9010, white 9016, bleached 1501, anthracite 7016, teak, nut and venge. For a small surcharge we offer such colours as: pine, graphite, rosewood, mahogany, cypress and aphromosia. An additional option is painting windows in RAL colours. This ensures that the window profiles have a uniform shade, without any visible wood structure.

For a small surcharge we can colour the profiles in such shades as: mahogany, rosewood, aphromosia, cypress, pine, graphite and venge. Another variant is the use of opaque lacquers in colours from the RAL palette, which allow you to obtain a uniform colour of the frames.
