These windows guarantee the highest energy efficiency. This is achieved through a thick wooden frame, a deeper embedded triple sealed unit and additional elements such as triple gaskets, low-emission glass, a warm spacer and the filling of the void between the panes with argon. This results in a very low heat transfer Uw coefficient of 0.8 W/m²K. Thanks to aluminium overlays on the outer surface, your windows will serve you for decades.

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.
