Curtain wall is the external wall enclosure of a building, which does not bear weight and hangs like a curtain. Therefore, it is also known as "curtain wall" and is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. Curtain walls are usually used on the outer side of the main structure, usually covering the surface of the main structure; The relative main structure has a certain degree of micro motion ability in the plane.
Why build curtain walls?
The main reason is to protect the main wall, in addition to wind and earthquake resistance, fire and sound insulation, and decoration.
The construction materials of curtain walls should be able to meet the advantages of lightweight, flexible design, strong seismic resistance, and beautiful appearance. Acrylic (PMMA, organic glass) stands out.
The density of acrylic material is only about 1.2g/m3, which can save a lot of manpower and material resources in processing, design and installation. Its excellent processability also facilitates designers to realize their own creativity;
While achieving lightweight, acrylic also has ideal material strength. Its impact resistance is about 11 times that of ordinary glass, with excellent wind and earthquake resistance, effectively protecting the main structure of the building;
Acrylic has a beautiful appearance, is transparent and crystal clear, and is also superior to many other materials in terms of decoration. The light transmittance is over 93%, and the fully transparent acrylic curtain wall is the preferred choice for modern office buildings, which can be seen everywhere in large city CDBs.
The quality requirements for acrylic materials used in curtain walls are very high, and they need to be able to be used normally under outdoor conditions for more than 20 years. Therefore, it is best to choose brand new acrylic sheets for curtain walls from manufacturers. The processing of large parts required for curtain wall construction also needs to be provided by manufacturers equipped with relevant equipment.
