Now, in the manufacture of a window from wood, it is not necessary to leave special gaps between the details, designed for further fluctuations in the sizes of wooden parts. Thermal conductivity of wood is much lower than thermal conductivity of metal -plastic. Therefore, the tightness and thermal insulation of Euro -octos, made of glued wooden beam, have become larger than metal -plastic windows. Among other important advantages inherent in any products made of wood are their attractive, natural appearance, which is not amenable to the complete imitation of decorative films of metal -plastic windows. Despite the higher price, today wooden euro -windows are becoming a fashionable and popular brand.
