Euro windows are wooden windows which we divide into depths of 68, 78 and 92 mm. This depth is connected to the depth of the insulated glass. For a 68 mm profile we use a 24 mm double insulated glass and for 78 and 92 mm profiles we use 36 and 44 mm triple insulated glass. The thickness of these glasses affects thermal insulation characteristics of the window. It can be stated that the thicker the profile, the better insulation characteristics of the window.
