1. Curtain wall: The external wall of the building is closed, bearing no load, and hung like a curtain.

2. Window: an opening in a wall or roof that allows light or air to enter a room.

Second, the characteristics are different.

1, curtain wall features:

(1) Curtain wall is an independent and complete whole structural system.

(2) Curtain walls are usually used on the outside of the main structure and generally cover the surface of the main structure.

(3) The curtain wall has a certain micro-motion ability relative to the main structure on the plane.

2, the window function:

(1) adopts heat-insulating aluminum alloy profiles, and the internal and external aluminum alloys are combined with heat-insulating tape by rolling.

(2) Insulating glass is used to improve heat insulation performance and sound insulation effect.

(3) The sliding window adopts independent sealing structure, and the sliding window adopts double rubber strips, double tops and four sealing structures; The flat window adopts the principle of equal pressure and adopts the structure of one hard, two soft and three seals, which has good air tightness and water tightness.

(4) High-grade accessories are selected, which are beautiful in appearance, flexible in operation, safe and reliable, and beneficial to the thermal insulation effect of windows.

Third, the roles are different.

1, curtain wall function:

(1) Lightweight

Compared with the same area, the mass of the glass curtain wall is about1/kloc-0 ~112, the mass of the wet wall decorated with marble and granite is about115, and the mass of the concrete hanging board is about/kloc-0. The mass of the internal and external walls of a general building is about 1/4 ~ 1/5 of the total building weight. Curtain wall can greatly reduce the weight of buildings, thus reducing the cost of foundation engineering.

(2) Flexible design

The artistic effect is very good. Architects can design various shapes according to their own needs. They can present different colors, coordinate with the surrounding environment, cooperate with the lighting and so on. , so that architecture and nature can be integrated, thus reducing the sense of oppression of high-rise buildings.

(3) Strong earthquake resistance.

The wind-resistant and earthquake-resistant flexible design is the best choice for high-rise buildings.

2, the window function:

(1) Windows need to be able to transmit light, so extra heat will come with sunlight.

(2) Windows need ventilation, so the circulating air may bring dust and mosquitoes.
