The use of laminated glass for building curtain walls is mainly based on its advantages in safety, impact resistance, sound and heat insulation, optical performance and so on. The following is a detailed introduction:
1. high safety: laminated glass is made of PVB (polyvinyl butyral) and other polymer materials sandwiched between two or more pieces of glass. When the glass is impacted and broken, the PVB film will stick the broken glass fragments together and will not form sharp fragments splashing around like ordinary glass, thus greatly reducing the risk of injury to people and objects, especially for high-rise building curtain walls and other occasions with high safety requirements.
2. strong impact resistance: laminated glass has good impact resistance and can withstand the impact of large external forces and is not easy to crack. This enables the building curtain wall to maintain good integrity in the face of natural disasters such as strong wind, rainstorm, hail and possible man-made damage, reduce the possibility of glass breakage and falling off, and ensure the safety of the building.
3. good sound insulation and heat insulation effect: the film layer in the middle of the laminated glass can effectively block the transmission of sound, has good sound insulation performance, can reduce the impact of external environmental noise on the indoor, and provide a quiet and comfortable indoor environment. At the same time, it can also block the transfer of heat to a certain extent, reduce the energy loss of buildings, play the role of heat insulation and energy saving, and help reduce the energy consumption of air conditioning and other equipment.
4. excellent optical performance: laminated glass can have good transparency and optical performance, can maintain a clear visual effect, so that the interior of the building can obtain sufficient natural lighting, at the same time, it can provide a certain degree of privacy protection, and avoid the complete peeping of the outside world on the indoor situation. In addition, by selecting glass and intermediate film with different colors and characteristics, the light can be filtered and adjusted to meet the needs of different architectural designs and functions.
