Laminated Glass

 

Introduction to Laminated Glass

Laminated glass consists of two or more layers of glass with a Poly Vinyl Butyral (PVB) interlayer, which bonds chemically and mechanically to the glass, providing both safety and performance features. This glass type is essential for applications where impact resistance and protection from UV radiation are required, effectively blocking 99% of UV light.

Key Features and Applications

PVB, a flexible and clear resin, enhances the glass's properties, making it suitable for critical areas like automobile windshields and architectural facades. Common brands of PVB include BUTACITE, SAFLEX, and TROSIFOL, with the interlayer typically starting at 0.38 mm in thickness.

Detailed Properties

  • PVB Variations: Thickness options include 0.38mm, 0.76mm, 1.14mm, and 1.52mm

  • Color Choices: From transparent to a spectrum of colors including greens and blues

  • Performance Ratings: High visible light transmittance at 89%, with a shading coefficient of 0.92

  • UV Protection: Effective UV screening up to 99%, crucial for protecting interiors from sun damage

Enhanced Safety and Security

Laminated glass is engineered to remain intact on impact, significantly reducing the risk of injury. It is also a deterrent against break-ins, providing a persistent barrier even when cracked.

Noise Reduction and Environmental Control

With superior sound dampening qualities, laminated glass is ideal for urban settings where noise reduction is paramount. It also excels in controlling solar heat gain in combination with other glass treatments, maintaining interior comfort while allowing ample daylight.

Protection Against Natural Elements

Specifically designed to withstand severe weather conditions, laminated glass is a reliable choice for coastal and other high-risk areas, preventing damage and injury from storm-driven debris.

Optical and Aesthetic Benefits

Laminated glass is preferred for architectural applications where minimal visual distortion is required, offering clearer and more accurate reflections compared to other glass types.
