At present our country the proportion of thermal insulation energy-saving Windows accounts for only 0.5% of the total, compared with Europe and the United States developed countries still there is a big gap. Europe in the early 80 s the development of high performance insulation energy-saving Windows and doors, 2003 European doors and Windows energy saving standards specified in the K value is not greater than 1.4, and the highest standards in our country at present is the K value is not greater than 2.8. Building energy efficiency is the key to doors and Windows energy saving. Therefore, building energy-saving Windows and doors technology and promotion and the growth of the huge space, also is the inevitable trend of market development.

At present, our main use of heat preservation and heat insulation performance and thermal insulation energy-saving Windows sealed performance is good material, in addition to choose good heat preservation effect of the doors and Windows material, the enterprise itself also needs to strengthen research and development of new resources as doors and Windows material, so as to meet the diverse needs of consumers. Reasonable design a good energy saving effect of energy-saving insulation Windows and doors, ensure high performance and high quality.

The stand or fall of quality, not only directly affects the heat loss and reserved, at the same time also determines the doors and Windows of life. While the doors and Windows installation technology to determine whether the doors and Windows can ease of use, etc., the technical level, an important part is to ensure that the building energy saving. Visible, energy-saving doors and Windows is widely used in the construction industry, vigorously develop energy-saving Windows and doors, the economic and social benefits, are extremely optimistic.
