New line of defense for building curtain wall safety: seismic performance of EVA laminated glass
EVA laminated glass is made of two or more layers of glass and EVA film bonded under high temperature and high pressure. EVA film has good flexibility and adhesion. When encountering earthquakes and other vibrations, it can act like a "cushion" to absorb and disperse the impact force generated by the earthquake. Even if the glass breaks, the EVA film can firmly stick the broken glass fragments so that they will not scatter, avoiding secondary damage and effectively ensuring the safety of people inside the building and pedestrians outside.
From the actual application effect, the seismic advantage of EVA laminated glass is very significant. In some construction projects in earthquake-prone areas, the curtain wall using EVA laminated glass only has a small amount of glass cracks after experiencing medium and low-intensity earthquakes, and the overall structure remains intact, effectively reducing the building damage and maintenance costs caused by earthquakes. Compared with ordinary glass curtain walls, EVA laminated glass curtain walls are more stable in terms of seismic resistance, greatly improving the seismic resistance level and safety of buildings.
In addition, EVA laminated glass not only has excellent earthquake resistance, but also has good sound insulation, heat insulation and optical properties. While providing earthquake protection for building curtain walls, it can also create a quiet and comfortable indoor environment, improve the energy efficiency of buildings, and reduce building energy consumption.
Nowadays, more and more modern buildings choose EVA laminated glass in curtain wall design. With its reliable earthquake resistance and comprehensive advantages, it is protecting the safety of buildings and becoming a new choice for the construction industry to ensure safety and pursue quality.
