Thanks to the latest technologies and years of work put in manufacturing timber windows and doors, we have created and developed windows for passive houses. Since the purpose of these houses is optimization of energy consumption and preservation of natural resources, timber windows have to contribute to this noble cause.


Window frames for passive houses are filled with special isothermal material, edge joints are extremely well insulated. Windows meet the European Union standards, they have very low thermal conductivity coefficient (U≤0.79) and the highest energy efficiency class A. In accordance with the standards of the European Union, window thermal conductivity coefficient must within 0.80 W/(m²K).


Such timber windows will allow to create not only an exclusive design, but also to achieve the maximum coziness while preserving warmth, naturalness and will allow to be nature friendly.
