Laminated glass is a type of safety glass that consists of two or more layers of glass with one or more layers of thin polymer material in between. This design prevents the glass from forming sharp fragments when it breaks, ensuring safety. Even under impact, the glass breaks in a “spider web”-like crack that keeps the fragments adhered to the interlayer.
Main Application Areas:
Laminated glass is widely used in a variety of fields, including:
Architecture: Used in windows, curtain walls, and exterior storefronts, especially in areas that require hurricane protection.
Automotive: Commonly found in windshields and skylights, providing greater safety.
Photovoltaic Equipment: Used in solar panels to improve performance.
UV Protection: Effectively blocks harmful ultraviolet rays to protect the indoor environment.
Artistic Expression: Show unique effects in art installations and designs.
Interlayer Materials
The interlayer of laminated glass is usually made of the following materials:
Polyvinyl butyral (PVB)
Ethylene vinyl acetate (EVA)
Ionoplastics
Cast-in-place liquid resins (CIP)
Thermoplastic polyurethanes (TPU)
Among them, TPU, PVB and EVA can effectively block almost all UV rays. For example, thermosetting EVA can block up to 99.9% of UV rays.
Sound insulation effect
Laminated glass performs well in sound insulation, especially when using EVA or TPU materials, and usually does not require additional acoustic materials. If PVB is used, a special acoustic PVB composite material is required to enhance the sound insulation effect.
Main advantages
The main advantages of laminated glass include:
Increased safety: In traffic accidents, laminated glass can remain intact, preventing glass fragments from injuring passengers, and it can also effectively prevent intrusion.
Reduced noise pollution: Compared with single-layer glass, laminated glass significantly reduces external noise at the same thickness.
Energy saving effect: Laminated glass can reduce solar radiation, keep the room cooler, and reduce energy consumption.
Natural Disaster Protection: Laminated glass can remain intact during natural disasters such as hurricanes or earthquakes, reducing the potential risk of casualties.
Conclusion
Laminated glass has become an indispensable material in modern buildings and transportation due to its superior safety, sound insulation and energy-saving properties. Laminated glass has demonstrated important value in improving passenger safety and reducing energy consumption and noise pollution.
