Durwin

The offer of DURWIN windows is addressed mainly to customers in the UK, Ireland and Scandinavian countries where outward opening windows dominate.
Wood-aluminum windows combine positive features of wood that is naturally beautiful and perfect construction material and aluminum resistant to external conditions.
 
Clever design and appropriate combination of these two different materials give excellent results.
DURWIN windows – nature inside and indestructible aluminum cladding outside.
 
Wood-aluminum windows virtually require no maintenance and are an investment for future generations.
They are perfect for buildings that are more exposed to weathering: mountain areas, coastal zones.
