Why Choose Laminated Glass?

What is laminated glass?

Laminated glass is a type of safety glass constructed from two or more glass sheets bonded together with an interlayer, typically PVB (a kind of film made by polyvinyl butyral). This creates a strong, unified structure that offers unique safety benefits compared to ordinary glass.

How is laminated glass manufactured?

• Glass Preparation: Two or more sheets of glass (often annealed or tempered) are cut to the required size. And then thoroughly cleaned by removing dust from the glass surface.

• Interlayer Placement: A sheet of PVB interlayer is placed between the glass sheets, holding the glass together.

• Deairing: The glass-interlayer stack is fed through a roller press or vacuum bag to squeeze out air bubbles and ensure the interlayer makes close contact with the glass surfaces. This prevents gaps that could reduce strength.

• Pre-Bonding: The assembly is heated (around 70–100°C) in an oven or with heated rollers. This softens the interlayer, allowing it to partially adhere to the glass and seal remaining small air pockets.

• Final Bonding: The stack is placed in an autoclave-a high-pressure, high-temperature chamber. Here, heat (120–140°C) melts the interlayer, and pressure (10–15 bar) forces it to fully bond with the glass, creating a single, unified panel.

What are the advantages of using laminated glass?

• Enhanced Safety

• When broken, the interlayer holds shattered glass pieces in place
• Prevents dangerous shards from falling or scattering

• Maintains structural integrity even after cracking

• Durability & Security

• Resistant to impacts, making forced entry more difficult
• Withstands temperature changes and weather conditions

• Performs well in both indoor and outdoor environments

• Additional Benefits

• Sound insulation: Reduces noise transmission between spaces
• UV protection: Blocks up to 99% of harmful UV rays, preventing furniture fading
• Design versatility: Available in various colors, tints, and finishes

• Glare reduction: Tinted options improve comfort in bright conditions
