In the present domestic energy saving wood door occupies proportion in construction projects, from the initial some high-end projects will use energy-saving Windows and doors, now with the popularity of green building, also the people's standard of living increasingly improve, energy-saving Windows and doors also gradually entered the ordinary people home quickly, it also can see energy-saving doors and Windows has been completely consumption recognize and accept this.

Each year in China's development of 40 billion square 1000 square with a window of high-end villa project quantity, wooden window also accounted for only 30%. Not to be the main reason for the widespread use of the price. In Germany, wood plastic window is the price of 1.6 times, and the price of aluminum alloy doors and Windows above wooden window again. This is determined by the K value. General K value in the case of 1.5 to 2.0, the price of plastic window in the every - 800-1200 yuan, broken bridge aluminum alloy doors and Windows in the every - 1200-1500 yuan. K value in 1.0, the price of aluminum alloy doors and Windows to achieve 2500 per ping yuan, much higher than wood. So wooden window with the loss of the K value and cost performance is greatly increased.

Will replace the traditional energy-saving doors and Windows doors and Windows

In the past ten years, the rapid development of the real estate industry, and then there is a part of the real estate developers prefer to ignore the quality risk of short-term choose inferior quality of the doors and Windows to increase their wealth, the high quality doors and Windows. But this is a good year for wood door industry, on the policy to promote the domestic building energy efficiency has a higher request, in many green technologies, green building materials, wood doors and Windows is the most mature, and the effect is good, cost-effective products.

With government prudent attitude of the real estate industry, from land examination and approval to sell the intervention of the regulation and control all the way, don't already made a huge profit space compression, ignored the quality problem of the heavy desk. Door window is the frequently used in construction, quality difference is obvious, so the high quality energy-saving Windows and doors in the policy, or the opinion is. In the future by the quality of the public real estate developers to the superior quality of the energy-saving Windows and doors as a selling point.

Energy saving wood doors and Windows development direction

To increase daylighting ventilated area or performance characteristics of modern architecture, doors and Windows in the building area is more and more big more full glass curtain wall construction, and doors and Windows of heat loss accounts for more than 40% of the total heat loss of buildings, doors and Windows energy saving is the key to building energy efficiency, sensitive parts of the doors and Windows is not only an energy gain and loss, and relations to lighting, ventilation, noise, facade. It puts forward higher requirements on doors and Windows of energy saving, the main energy saving treatment is to improve the material of heat preservation and heat insulation performance and improve the airtight performance of doors and Windows.

On the development of the window, balcony window to the ground push-pull type development, the development of new type of suspension and the suspension type window; Main development transom, toilet is the line of sight and ventilation two functions; The kitchen window to strip window development, in the kitchen between condole ark and work station; Doors and Windows shading technology is suitable for widely in hot summer and warm winter area.
