1. Curtain wall is an independent and complete overall structural system;
2. Curtain walls are usually used on the outside of the main structure, and are generally covered on the surface of the main structure;
3. The curtain wall has a certain micro-movement ability in the plane relative to the main structure.
The ventilation height of the curtain wall may be the height of a single storey, a multi-storey or even an entire building, or some combination of the above. The most common is the single-storey height structure, the advantages of single-storey double-layer curtain wall: separate fire, smoke, smell and noise between floors, and easy to achieve standardized design and production of curtain wall units. In temperate climates such as continental Europe and the United Kingdom, double-layer curtain walls are widely used in the construction industry. Experts in the construction industry believe that double-layer curtain walls can reduce cooling load, facilitate good natural ventilation, facilitate lighting, control noise, and reduce thermal energy consumption.
The development trend of curtain wall:
1. From bulkiness to lighter panels and structures.
2. Gradually move towards more types of plates and richer colors with fewer varieties.
3. Higher security performance.
4. More flexible and convenient construction technology.
5. Higher waterproof performance, extending the life of the curtain wall).
6. Environmental protection and energy saving.
The economical double-layer ventilation curtain wall adopts the structural form of an integral unit system, and the spacing between the inner and outer curtain wall panels is 155mm. The whole system structure is light, concise and economical. The curtain wall frame adopts aluminum alloy keel, which is processed, produced and assembled in the factory; the surface material is made of insulating glass, single-layer glass and lined with thermal insulation decorative board; The hardware accessories of the alloy contact parts are made of stainless steel. It is then transported to the site and hung directly on the main structure of the building.
A curtain wall is a non-load-bearing exterior wall cladding that is hung to the exterior of the building, usually spanning from floor to floor. Curtain wall vertical framing members run past the face of floor slabs, and provision for anchorage is typically made at vertical framing members only.
Generally speaking, there are two main types of curtain wall systems, unitized curtain wall and stick curtain wall.
Whereas curtain walling is usually made from an aluminium frame with large glass panes, cladding can be made from a variety of different materials. Some popular cladding materials include wood, metal, concrete, and reinforced PVCu.
