The best material, for the frames and wings of the windows, has always been and still remains wood. The disadvantages of the wooden structure include its fire hazard and high cost, and otherwise, in all indicators, wooden windows are largely ahead of metal and plastic structures. A big plus is that you can make windows of any shape; round or oval, trapezoid or triangular. Companies that produce high -quality wooden windows quite a lot, but I advise this.
Advantages of wooden windows
Wood structures have always been used in construction. Modern wooden wings are not deformed over time, and glued beam is material, it has greater strength than a whole.
Metal or polyvinyl chloride, unlike wood, cannot be called breathable materials. Wooden windows have an electrostatic charge, and the paintwork that the frames cover are absolutely safe.
The physico-mechanical properties of wooden frames are much stronger and more plastic, compared with metal or plastic structures. This means that wooden windows are very resistant to deformations and can withstand large tensile or compression loads. Most often used for the production of window frames by local wood, such as pine or oak. Some foreign breeds can be called popular-Merant and Mahagoni, which grow in Southeast Asia. The frames covered with a special fire resistance can withstand fire for a long time. Making their choice in favor of wood, manufacturers always take into account various positive qualities of the material.
Window frames made of wood have their positive properties:
light weight of the entire structure;
low sound conductivity;
maintainability;
High frost resistance.
How to choose a wooden window?
Only glued beam should be the material for the production of a wooden window. The varnishing and painting process should be strictly observed so that over time it is not necessary to repaint the frames. On the outside of the window, there must necessarily be tide for water drainage. Window installation should be as accurate as possible. Solid companies, I advise this, always give a guarantee for a certain period, during this period you can replace or repair the window for free.
