A: Good insulation properties --- The windows are distributing heat up the building site, can be said to maintain the structure of the weak link, according to a study measuring the construction sector, 40% of energy consumption in buildings is generally from the windows sporadically. Heat transfer are conduction, convection and radiation in three forms; conduction occurs mainly in the window frame and sash, convection occurs at the seal doors and windows and crevice, radiation mainly in the glass surface. Because wood is an excellent insulation material, low thermal conductivity, thermal bridge blocked. Modern wooden structure and effectively ensure the tightness and leakage of rainwater. Therefore, a high-performance wooden windows can be reduced by 15% of building energy consumption. In the cold winter indoor temperature above 20 ℃ and the outdoor temperature is below -25 ℃ using high-performance aluminum-clad wooden windows, the energy principle, same as reducing the transfer of heat and reduces energy consumption. B: Good insulation performance --- glass hollow glass, hollow glass hollow space of 12mm, after the whole window installation, indoor and outdoor air can not achieve communication, thus, making insulation, sound insulation performance live up to the desired results. Broken Bridge + hollow "structure makes doors and windows energy saving, environmental protection has been fully reflected. This structure enhances the sound insulation and sealing, insulation can play the role of insulation, greatly reducing energy consumption for heating and cooling. The main groove aluminum double-sealed insulating glass, hollow glass bead its flatness, good transparency, heat, noise and strong, filling an aluminum gutter molecular sieves, can fully absorb water between two layers of glass, Thus windows and doors will not appear Mist, Cream and so excellent noise performance, noise can be reduced by about 25dB C:.. appearance, good decorative properties --- in many construction materials, visual effects and tactile effects of the best wood, pleasant natural color of wood, different species have different style and color, unlike steel windows, aluminum windows, plastic window sparkling, cold feeling, it can create a very harmonious and pleasant environment D: corrosion resistance - - External aluminum window through high-tech surface treatment, resistant to salt, acid and alkaline corrosive substances, residents of coastal areas are particularly effective E: Strong --- tightness between the frame and the fan, glass and. How Road between sealing strip timber, greatly reduce the loss of indoor energy F:. watertight and strong --- bottom window mount aluminum gutters notch with internal drainage holes ensure runoff rainwater, thereby enhancing the water tightness Use insulating glass between the glass and the frame pad mat dedicated access, play a damping effect, fans outside the box offices with a special isolation tape lap isolation, to prevent rainwater directly into the interior G: easy to clean - - The selected profile is not affected by dust, adhesives and cement, maintenance probability is very small, even if somewhat dirty, clean water to H: long life --- Historically, China's ancient wooden structure. window after several centuries of vicissitudes, and preserved everywhere. From the point of view of modern, fifties and sixties of the last century building, the windows are all basically made of wood, and now continue to use it fully proved correct structure design, reasonable drying, preservation conditions, maintain regular repair and paint, wooden windows can achieve a long service life. outer aluminum afraid of the wind, not afraid of the sea climate and acid rain, will not rust, sun and rain not aging, so that the European Window longest life URL:. http: //www.zzhxmc.cn/ Zhengzhou factory doors and windows, closed balcony Zhengzhou, Zhengzhou bridge Cailv doors processing installation http: //www.zzglygf. com / Zhengzhou sun room, closed balcony Zhengzhou, Zhengzhou bridge closed balcony Cailv | Price Zhengzhou factory doors and windows, sun room installed in Henan, Henan bridge Cailv doors, closed balcony Zhengzhou, Henan factory doors and windows, Zhengzhou bridge Cailv windows and doors processing installation, Zhengzhou sun room, closed balcony Cailv bridge Zhengzhou, Zhengzhou closed balcony installation, Zhengzhou bridge closed balcony Cailv price, sun room installed in Henan, Zhengzhou bridge Cailv doors and windows processing, Zhengzhou sun room installed, Henan off Cailv bridge windows and doors processing, processing of Zhengzhou sun room, bridge Cailv windows prices Henan, Zhengzhou doors and windows processing, color aluminum doors and windows broken bridge price Zhengzhou, Zhengzhou closed balcony installation, Henan sun room, sun room prices Henan, Henan sun room installation
