Energy-saving doors and windows will become mainstream, and analysis of four major energy-saving doors and windows

The national “Twelfth Five-Year Plan” has more clearly defined the goals of energy conservation and emission reduction, and building energy conservation is also an important part of energy conservation and emission reduction and has also received attention from relevant departments.

Doors and windows as an important force in building energy efficiency also received much attention. Ya Zhi Xuan, said the person in charge of windows and doors: "Energy-saving doors and windows will become the mainstream products of the future door and window market. For some of our Yaxuan began research and development of energy-saving products as early as a few years ago, now the door and window products are in full compliance with the national energy-saving requirements."

The manager of Longma Wood Industry reminded us that if the installation is not standardized, even if the materials are properly selected, it is difficult to achieve the effect of energy conservation. At present, the energy-saving doors and windows on the market are divided according to materials, including steel doors and windows, energy-saving aluminum alloy windows, pure wood and aluminum-clad wooden doors and windows, and composite material windows.

The most significant characteristics of steel doors and windows with energy-saving plastic steel doors and windows are significant energy saving, excellent air tightness, watertightness, sound insulation and heat preservation, and good corrosion resistance, without frequent maintenance. However, the style of the window is small and single, the level of hardware is not high, and product installation and after-sales service are not in place.

The price difference between steel doors and windows is mainly determined by five aspects. The first is the quality of the profiles, good 18,000 yuan per ton, less than 10,000 yuan per ton; followed by glass, single glass, double glass, insulating glass prices are different; the third is the hardware, the difference between high and low prices 10 times; four seals, a few cents per meter, but also more than 1 yuan a meter; five is the installation and service. Various factors come together and the price is between 500 yuan and 700 yuan.

The energy-saving aluminum alloy window is expensive, and the aluminum alloy has light weight and high strength, corrosion resistance, small deformation, and long service life without any pollution. Energy-saving aluminum alloy profiles have been used since the mid-1990s. New technology has been used to separate the interior and exterior of aluminum window frames with reinforced nylon to block the exchange of internal and external energy. It is suitable for high-rise buildings, public buildings and other projects. The market price of aluminum alloy doors and windows with cut off heat is between 1,000 yuan and 1,800 yuan.

The wooden windows have undergone qualitative changes. Pure wood windows use glulam, and the wood undergoes special processing to improve its anti-corrosion capability. Although the quality of pure wood window is first class, but the cost is high, some of the market price of 3,000 yuan per square meter, generally suitable for villas and other noble low-rise housing.

Aluminium wood window is attached to aluminum outside the pure wood window. The aluminum alloy is fixed to the wooden product with a nylon lock, which greatly enhances the durability of the pure wood door and window.

Composite material window to increase strength Composite material main structure is energy-saving aluminum alloy, which combines the advantages of energy-saving aluminum alloy window and wood window. The interior decoration material is pure wood, showing the characteristics of advanced wooden doors and windows. The outdoor use of broken bridge aluminum alloy, aluminum alloy doors and windows to retain the excellent weather resistance. Due to the combination of aluminum and wood, it has a higher rigidity and greater lighting ventilation area. The price of such doors and windows is about 2,000 yuan per square meter.

The installation service pointed out that the person in charge of the gates and windows at the last Guanrui Gate stated that the door and window industry has a “three-point production seven-point installation” argument. Door and window quality problems are mostly caused by installation, and installation requirements for energy-saving doors and windows are more stringent. Under normal circumstances, manufacturers will come to the door measurement, design open, installation and other content, the purchase process is relatively long and more complex, and the new window used to maintain, after-sales items are also many, so the door and window service is particularly important. Consumers should clearly install materials and install labor costs in the contract.
