The PVB laminated glass is also known as laminated safety glass or laminated security glass. It consists of two or more layers of glass bonded together with a PVB film, which is a specialized plastic material possessing exceptional properties of adhesion, elasticity, transparency, and resistance. This type of glass exhibits high strength and provides dual protection against severe injuries. Due to the presence of the PVB film, even when the glass shatters, the fragments remain adhered to it instead of falling onto the floor with sharp edges. Furthermore, the shattered pieces stay within the window or frame, effectively preventing forceful break-in attempts and heavy impacts.
Additionally, its energy-saving properties are noteworthy. The PVB film reduces solar heat transmission, lowering cooling costs in warm climates. For architectural applications, it allows natural light penetration while minimizing glare and UV damage to interiors. The material's versatility extends to customizable tints and patterns, offering aesthetic flexibility without compromising safety. Its durability also reduces long-term replacement costs, making it a cost-effective solution for high-impact environments.
The application of PVB laminated glass is extensive. It is widely used in architectural glazing for both structural and decorative purposes, including:
| Inter-layer material | PVB |
| PVB color | clear, white, milky white, any pantone colors |
| Shape | flat laminated glass |
| Glass color | clear laminated glass, acid etched laminated glass, printed laminated glass, blue laminated glass, green laminated glass, gray laminated glass, bronze laminated glass etc |
| Single glass Thickness | 3mm to 19mm |
| PVB Thickness | 0.38mm, 0.76mm, 1.14mm, 1.52mm, 1.9mm, 2.28mm |
| Glass size | Maximum 3300x13000 mm |
PVB laminated glass, also known as laminated safety or security glass, consists of two or more layers of glass bonded together with a PVB (polyvinyl butyral) film. It provides high strength, elasticity, and transparency.
When the glass shatters, the fragments remain adhered to the PVB film instead of falling with sharp edges. This keeps the shattered pieces within the frame, effectively preventing forced entry attempts and reducing injury risks.
The PVB interlayer reduces solar heat transmission, which lowers cooling costs in warm climates. It also allows natural light inside while minimizing glare and shielding interiors from harmful UV damage.
Single glass thicknesses range from 3mm to 19mm, while PVB film thicknesses range from 0.38mm to 2.28mm. Glass colors include clear, acid etched, printed, blue, green, gray, and bronze, with various customizable PVB colors.
The maximum production size for flat PVB laminated glass is 3300x13000 mm, allowing it to meet large-scale architectural and structural specifications.
