The application of architectural curtain walls in China began in 1984 years. After nearly two decades of development, so far, the annual output and ownership of architectural curtain walls in China have ranked first in the world. But in recent years, with the intensification of competition, the saturation of the market, the decline of prices and the reduction of profits, everyone in the curtain wall industry is thinking: What kind of curtain wall does the market need? The editor believes that energy-saving and environmentally friendly curtain wall products will be the stars of the future market.

Some energy-saving and environmental protection measures currently adopted in the design and application of building curtain walls are:

　　1. Insulating glass, especially LOW-E insulating glass technology

Ordinary white glass 6 mm, k value is about {{{{{{{}} 0}}}} w / ㎡k; {{{{1 0}}}} + {{ 0}} + {{{{{{{}} 0}}}}} ordinary insulating glass, K value is about 2. 6 ~ 3. {{{{{{ 12}} 0}}}} w / ㎡k; if LOW-E insulating glass is used and filled with argon, the K value can reach {{1 0}}. 6 ~ {{{{ 12}} 0}}. 8 w / ㎡k. LOW-E insulating glass has obvious energy saving and environmental protection effects. In winter, it can effectively prevent the heat radiation of indoor heating from leaking out; in summer, it can prevent outside heat radiation from entering the room. 00 {{1 0}} 00 {{1 0}} 0 nbsp;

Double energy savingbuildingCurtain wall glassIt is mainly divided into internal circulation and external circulation systems, which have their common points and different points. The common feature is that a greenhouse effect is formed between double glazing, and the superheated air in the greenhouse in summer is excluded from the outdoor, and the solar thermal energy is linked in winter The system is discharged into the room, so that the winter and summer seasons have a lot of energy.

In summer, it is necessary to require sunshade for the protection against ultraviolet rays and strong heat radiation, and the inner circulation and outer circulation systems.

At present, China has introduced two production process technologies and complete sets of special equipment: "injection plastic method to cut off heat aluminum profile" and "insert strip method to cut off aluminum profile". In terms of market demand, the market share of thermally insulated aluminum doors and windows has been rising in the past two years.
