Advantages of Lumen Wooden Windows:
SOFTLINE Window. Classical solutions, modern form and intrinsic beauty of wood-these are prime features of Softline product range. Thanks to their rounded edges and gentle shapes we gave our windows austhetic design maintaining very good window performance.
For both window frame and casement, the heat transfer coefficient is U=1.3 -:- 1.4 W/m2K, depending on the wood species, which means excellent heat insulating properties. This is conditioned by: wood structure (porous and fibrous), profile shape and thickness (68 mm), structural groove system and the shaped solution of seal places between casement frame. This provides an excellent protection against rain, wind, impurities and noise-maintaining optimum ventilation of enclosed spaces.
In the manufacture we use such wood species as pine, oak and meranti.
Window profiles are made of 3-4 layer laminated cant. Now, this is the best way to eliminate timber tendency to warp due to variable ambient humidity. The planks are bonded and so laid that internal stress in the layers is mutually compensated and the profile remains unwarped. Before bonding they are subjected to disiccation (following the optimum procedure for each species) and antifungal, especially antimould, preservation to increase the final product longevity.
There is also the possibility of providing the windows with additional decorative elements, such as divisions, arches, stained glass, carved components, as well as handles in various shapes and colors.

Perfect - on the casement outside edge there is an extra aluminum shield to protect this part of window against solar radiation and rain.
