In Europe and America, most building glass uses PVB laminated glass. This is not only to avoid injury accidents, but also because PVB laminated glass has excellent seismic intrusion resistance. The interlayer film can withstand continuous attacks from weapons such as hammers and firewood knives. Special PVB laminated glass can also resist bullet penetration for a considerable period of time. Its level of security protection can be said to be extremely high.
Whether the sound insulation effect of modern residences is good or not has become one of the important factors for people to measure the quality of housing. Laminated glass with PVB film can block sound waves and maintain a quiet and comfortable office environment. Its unique function of filtering ultraviolet rays not only protects people's skin health but also keeps valuable furniture, display items and other items at home from fading. It can also reduce the transmission of sunlight and lower the energy consumption for cooling.
PVB laminated glass can also have unexpected good effects when used in home decoration. For instance, many household doors, including those in the kitchen, are made of frosted glass. When cooking rice, the kitchen fumes tend to accumulate on it. If laminated glass is used instead, this problem won't occur. Similarly, large areas of glass partitions at home pose a safety hazard to naturally active children. If laminated glass is used, parents can rest assured.
PVB laminated glass can break safely. It may shatter under the impact of a heavy ball, but the entire piece of glass remains intact, and the broken pieces and sharp small fragments still stick to the interlayer film. Tempered glass requires a considerable impact force to break. Once it breaks, the entire piece of glass shatters into countless fine particles, leaving only a few broken pieces in the frame. Ordinary glass shatters easily upon impact, presenting a typical breaking condition and generating many long, sharp-edged fragments. When laminated glass breaks, mirror-toothed fragments surround the opening, and there are many glass fragments left around the penetration point. The lengths of the broken metal wires vary.
