Our wood/aluminum windows in the WD profile line are well suited to low-energy and passive homes. The combination of natural materials with aluminum cladding imparts the house with a special look. Our customers, architects and designers all like this combination due to the opportunity to select a color matching that of the facade and other construction elements, while at the same time on the interior you can enjoy the view of beautiful wood coated with natural glazing or a topcoat.

Wood/aluminum windows are easy to maintain and keep in good condition. The design of the wood/aluminum windows matches current trendswhile meticulous workmanship guarantees a very long service life and hence appreciation of your investment.

While buying our wood/aluminum windows you can also select a perfectly fitting entrance door with the same design/patterns.

Wood/aluminum windows are distinguished by their top-rate design and outstanding thermal insulating properties. Wood cladding with aluminum improves the resistance of the windows to the effects of weather, thereby extending their service life.


We offer 4 profiles of wood/aluminum windows, each with different frame design depths. The depth affects the window’s heat- and sound-insulating capacity.


  • All wooden interior structure
  • Aluminum cladding on the exterior side, welded or bonded in the corners.
  • Wood with first-class surface finishing on the internal side
  • Perfect workmanship, excellent design
  • Aluminum surface finish with a powder coat in approximately 20 colors

All our wood/aluminum windows are tailor-made to fit a specific building, in any shape and configuration. We use top-quality MACO and SIEGENIA fitting.

Please specify the desired fitting type, size, shape and configuration in your inquiry.


Our wood/aluminum windows consist of a massive wooden structure and aluminum cladding protecting the window from the exterior side.

You can select from a range of wood species, each differing in their thermal insulating properties and in the characteristic patterns. You may modify the wood color by selecting a glaze or topcoat. The wood species and properties affect the service life and price of the product.

We use high-quality aluminum profiles for the cladding, bonded or welded in the corners. The aluminum surface is coated with powder paint in nearly any color you wish. The natural aluminum properties along with the surface finish guarantee a high aesthetic value and outstanding use properties of our windows lasting for decades.
