The great environment of social trends has an indelible influence on the development of enterprises. Environmental protection is still an eternal theme in the long-term development of social development, and it is also an embodiment of the responsibility of production enterprises. In recent years, the construction industry has developed into the largest energy-consuming industry in China, accounting for 30% of the total energy consumption of the society. With the introduction of a series of standard measures in various industries, the concept of low-carbon energy conservation has penetrated the hearts of consumers and how to save energy. Environmental protection is a major problem for building materials companies to adapt to the needs of society.

According to statistics, more than 97% of the buildings in many cities in China are high-energy-consumption buildings. It is estimated that by 2020, the country's high-energy building area will reach 70 billion square meters, directly aggravating China's energy crisis. During the “Twelfth Five-Year Plan” period, Beijing proposed the “Design Standard for Energy Efficiency of Residential Buildings”, which clearly defined the heat transfer coefficient K value that has a judging effect on energy saving of doors and windows, and put forward higher requirements for energy saving of doors and windows.

Then, several major products in the door and window market - aluminum alloy windows, plastic steel doors and windows, broken aluminum doors and windows, aluminum wood composite doors and windows, solid wood doors and windows, how to rationally choose according to its energy saving and environmental protection?

First, aluminum alloy doors and windows

While aluminum alloy doors and windows still maintain market share, the shortcomings of heat conduction are still difficult to solve. In order to reduce the heat transfer coefficient, it is necessary to increase the coefficient and increase the length of the heat insulation strip and change the shape of the heat insulation strip. The difficulty is greater, which is one of the reasons for the low market share of aluminum alloy doors and windows in developed countries in Europe and America, so even though it is not cheap.

Second, plastic steel doors and windows

Plastic steel doors and windows are poor conductors in heat transfer, and the heat transfer coefficient is low. However, after the introduction of new energy-saving standards, such products have been difficult to meet the requirements. With the rise of raw materials and irregularities of operators, plastic doors and windows are also Faced with a severe test.

Third, broken aluminum doors and windows

The current aluminum door and window of the broken bridge has outstanding advantages such as high strength, good thermal insulation, good rigidity, good fire resistance, large lighting area, good atmospheric corrosion resistance, high comprehensive performance, long service life and good decorative effect. More and more favored by the market.

Fourth, aluminum wood composite doors and windows

In recent years, the aluminum-wood composite doors and windows on the market (with the main structure of the broken bridge aluminum inlaid with wood) have become the new expensive with its high energy-saving and environmentally-friendly cost performance and significant advantages.

In addition to the irreplaceable aesthetic effect, the biggest feature of aluminum-wood composite doors and windows is the “broken bridge + hollow” structure, which makes the energy saving and environmental protection fully reflected. This structure also enhances the sound insulation and sealing performance. Insulation and insulation greatly reduce the energy consumption of heating and cooling.

Five, solid wood doors and windows

Solid wood doors and windows have natural thermal insulation properties, but wood is also a non-renewable resource. From an environmental point of view, large-scale use of solid wood doors and windows does not meet energy conservation and environmental standards.

From the overall trend, the market with absolute advantages of aluminum alloy doors and windows has been transformed, and new energy-saving and environmentally-friendly broken aluminum doors and windows and aluminum-wood composite doors and windows have become the new favorite in the future. For the production enterprises, no matter which material the doors and windows, should be from a practical and reasonable point of view, under the premise of meeting the industry standards, reduce energy consumption, so that new technology as a true core competitiveness.
