What is laminated glass?

Laminated glass is a high-performance safety and security glass composed of two or more layers of glass permanently bonded together with one or more plastic interlayers, typically Polyvinyl Butyral (PVB) or SentryGlas (SGP). The lamination process involves heat and pressure to ensure a clear, strong bond. The standout feature of laminated glass is its ability to stay intact even when shattered. If the glass breaks, the fragments adhere to the internal plastic layer, maintaining the integrity of the opening and preventing dangerous shards from scattering. This property makes it an essential component for security applications, as it provides a formidable barrier against forced entry, smash-and-grab robberies, and even ballistic threats depending on the thickness and number of layers. Beyond security, laminated glass offers exceptional sound insulation, significantly reducing outside noise, and blocks up to 99% of harmful UV rays, protecting interior furnishings from fading. It is commonly used in storefronts, airports, government buildings, and residential windows in high-traffic or high-crime areas. Because it remains in the frame after breaking, it also provides protection against weather events like hurricanes by preventing wind and debris from entering the building.
