Industry development: China's energy saving doors and windows show three characteristics

All doors and windows with thermal insulation performance and air permeability performance and other physical performance indicators are equal to or higher than the Ministry of Construction's "Environmental Energy Efficiency Design Standards for Civil Buildings" and the building doors and windows products issued by the provinces, municipalities and autonomous regions issued technical requirements, all collectively known as Energy-saving doors and windows. It is understood that China's energy-saving doors and windows industry has emerged in three aspects more obvious features.

The scale of the industry continues to expand into the 21st century, the annual demand for doors and windows in China is nearly 500 million square meters. At the same time, national government departments have repeatedly issued new policies for building energy efficiency, and provinces, municipalities, and autonomous regions have also formulated local building energy conservation design standards. Under such circumstances, the building doors and windows industry has accelerated the pace of technological innovation, product upgrading, and quality improvement, and has introduced a wide range of new types of environmental protection and energy-saving products to the society, enabling the industry to achieve unprecedented development.

It is understood that the proportion of door and window products that meet the energy efficiency design standards for buildings across the country is about 50%. According to experts from the China Construction Machinery Corporation Building Doors and Windows Curtain Wall Design Institute, due to the higher technical content of energy-saving door and window products than ordinary products, the State Administration of Quality Supervision has inspected and inspected them to a large extent, resulting in a higher value-added of energy-saving door and window products than ordinary products. product. The profit rate of general qualified energy-saving door and window products is about 12%-15%. Compared with traditional door and window products with less than 5% profit margin, energy-saving doors and windows are obviously favored by enterprises. Therefore, in recent years, many profile manufacturers and curtain wall enterprises with a certain strength have joined the energy-saving doors and windows industry, so that the scale of the industry continues to expand.

The backbone strength has formed for the energy-saving doors and windows market, which has the characteristics of centralized engineering and large amount of invested capital. It requires companies to have relatively high design capabilities, exquisite processing technology and mature construction technology, which forms a financial barrier for small-scale enterprises. . Large-scale backbone enterprises have rapidly occupied a large number of markets with their strength and reputation, and their scale advantage has been highlighted.

The potential of innovative products is huge. It is understood that although China's energy-saving doors and windows industry has achieved considerable development, compared with market demand, there are still some problems, its main forms of expression are two aspects: First, all-weather issues of the product, and second, price-performance issues . All-weather products refer to door and window products that can meet the requirements of China's vast areas and different climatic conditions. They can meet the requirements of winter insulation and summer heat insulation in the northern regions, and can meet the seawater corrosion and solar radiation prevention standards in the southern coastal areas. The issue of cost-effectiveness refers to how to make more new energy-saving door and window products into the homes of ordinary people who still live in old houses.
