PVB Laminated Glass

Product Introduction

PVB Laminated Glass is a type of safety glass made by bonding two or more layers of glass with a polyvinyl butyral (PVB) interlayer under heat and pressure. This construction creates a single, solid sheet that holds together upon impact, reducing the risk of injury. Known for its durability, security, and acoustic insulation, PVB laminated glass is widely used in architecture, automotive, and interior design applications.

Product Features

High Safety Performance: If broken, the glass fragments remain bonded to the PVB interlayer, minimizing injury risks.

Sound Insulation: The PVB layer dampens sound transmission, making it ideal for noise-sensitive environments.

UV Protection: Blocks up to 99% of harmful UV rays, helping to protect interiors and furnishings from fading.

Durability: Maintains structural integrity even after breakage, offering protection against forced entry and weather impacts.

Customizable Appearance: Available in clear, tinted, frosted, or colored interlayers for aesthetic flexibility.

FAQ

Q1: What happens when PVB laminated glass breaks?

A: The glass cracks but remains intact, held together by the PVB interlayer, preventing shattering and injury.

Q2: Can laminated glass be used as structural glass?

A: Yes. With the right glass combination and thickness, laminated glass can be used for load-bearing applications like floors, stairs, and glass beams.

Q3: Is PVB laminated glass suitable for outdoor use?

A: Absolutely. It resists UV and weathering, making it ideal for facades, canopies, and skylights.

Q4: What colors are available for the PVB interlayer?

A: PVB interlayers are available in clear, milky white, bronze, grey, green, blue, and custom colors on request.

Q5: Is laminated glass heavier than normal glass?

A: Yes, due to the additional layers and interlayer, it’s heavier and requires appropriate structural support.
