Due to its high safety, laminated glass is gaining increasing attention. In the field of architectural glass, PVB laminated glass and SGP laminated glass are the most common. This article will provide a detailed introduction to the differences between PVB laminated glass and SGP laminated glass.
PVB stands for polyvinyl butyral, which has characteristics such as high transparency, sound insulation, cold resistance, impact resistance, and UV radiation resistance. PVB is currently the most widely used interlayer material for architectural and automotive glass. SGP stands for SentryGlas® Plus, an ionomeric interlayer material developed by DuPont, which is known for its high performance.
SGP laminated glass has twice the load-bearing capacity of laminated PVB glass of the same thickness; additionally, the deflection of SGP laminated glass under equal load and thickness is only 1/4 of that of laminated PVB glass.
PVB laminated glass is widely used in the following fields:
Construction industry: building curtain walls, sun rooms, doors and windows, stairs, railings, and other places.
Automobile industry: the windshield of a car usually uses laminated glass to enhance the safety and comfort of the driver and passengers.
Transportation facilities: such as glass curtain walls and soundproof screens in train stations, airports, bus stations, and other transportation facilities.
SGP laminated glass is widely used in the following fields:
Places prone to personal safety incidents: such as street-facing windows, building glass barriers, balcony doors and windows, airport terminals, glass canopies, glass atriums, and slanted glass windows.
Buildings requiring bulletproof, anti-theft, explosion-proof, and hail-resistant properties: such as banks, museums, exhibition halls, jewelry stores, etc.
Structures that need to withstand high pressure while meeting transparent observation conditions: floors, glass corridors, glass walkways, submarine windows, deep-water portholes, and viewing aquariums.
High-performance curtain wall glass: safety glass for high-rise buildings and large public buildings.
