Wooden windows
PRESTIGIOUS WOODEN SYSTEM
SOFTLINE and SOFTLINE XL windows. Classic solutions, modern form and natural beauty of wood - these are the most important features of Softline windows. Thanks to rounded edges and gentle shapes, we have given our windows an aesthetic design while maintaining very good technical parameters.
