Durwin Line - wood aluclad window.

This outward opening windows have been developed in view of recipients from the Northern Europe where this type of joinery is most popular. Their carefully designed, slim construction gives the impression of simplicity and sublime elegance.

Characteristic for these windows is their design and the method of opening the joinery – to outside, which increases the amount of space available in the room. Thanks to this solution, items may be left on the sill when opening the window.
Additional sealing in windy conditions is provided by the profile structure, where the window sash is pressed against the frame. As a result, the harder the wind blows, the more tightly the gasket adheres, and the more secure is the window.

The use of high quality materials: selected glued scantlings, multi-clamp ferrules, heat protection glazing units, and modern production technology allows obtaining a product with excellent aesthetic and functional parameters.

Such a unique design allows for easy maintenance and ensures every window stays in optimum condition for longer periods of time. They are perfect for buildings that are more exposed to weathering: mountain areas, coastal zones.
