Problems existing in building doors and Windows industry

In the national science and technology support plan of the eleventh five-year, twelfth five-year window scientific research topic research and the promotion and application of building doors and Windows, through in-depth research, summed up the following problems in the door and window industry:

1. Because the research and promotion of building doors and Windows lags behind the requirements of building energy saving work, the current external doors and Windows products can not fully meet the needs of energy saving engineering, and the proportion of energy saving external doors and Windows is low.

2. The research and development system of building doors and Windows is mainly based on profile factory as the leading enterprise. Profile factory often does not understand the engineering application technology of doors and Windows; Doors and Windows factory to assemble doors and Windows, research and development of technical strength is insufficient. The imported products can not meet the climatic conditions of large area in China, so it is difficult to form a perfect product system.

3. The design, production, installation and construction acceptance of the doors and Windows of the building are not systematic, and the standards are not matched. Lack unified design requirement, product standard does not consider installation requirement, and check and accept standard requirement too simple, make door window manufacturer do not know what to do.

4. Poor market environment leads to low-price competition, and inferior products flood the market.
