Wood and wood-aluminium windows are identical in their structure. Unlike wood window where the bottom part of sash and frame is covered with aluminium profiles, the outer structures of wood-aluminium windows are fully covered with aluminium profiles to ensure the most efficient protection against the effects of external environment.

Inward opening (the so-called German type) windows are manufactured from finger jointed 3 or 4 layer glulam pinewood. Cuctomized orders include other types of timber: spruce, oak, merant, mahogany, etc. Also, glulam timber without finger joints can be ordered.
IV78 profile combines good thermal insulation as well as diverse design options. Various shapes and colours (based on RAL color chart, glazes based on glaze catalogue) open up diverse architectural solutions.

- to ensure weather and waterproof properties, horizontal wooden parts are fully covered outside with aluminium water bars
Standard solution:
- glazing type: triple glazing with two selective glasses and argon filling (3K 4sel-16ar-4-16ar-4sel)
- thermal insulation: Uw= 0.88W/m²K
- finishing: one colour
