A wooden vertical window that extends the sloping roof window. It is a great way to create a bright and spacious arrangement of the attic. The unique design uses a large glazing area to illuminate the interior with natural light. It has been designed to combine the advantages of a roof window with a facade window. The best effect can be obtained by combining such windows in groups (the so-called combi assembly – two or more windows next to each other). The specificity of the IKDU structure allows the sash to be tilted, thanks to which the rooms can be better aired.
