Glass Lamination Unit

Product Specification

Glass Lamination Units (GLUs), a cornerstone of modern architectural and safety glass applications. We’ll delve into their composition, various types, applications, and benefits, including both the industry-standard Polyvinyl Butyral (PVB) and Ethylene Vinyl Acetate (EVA) lamination methods.

Understanding the Building Blocks:

  • Glass Lites: The foundation of a GLU. These can be tempered glass (shatters into blunt pieces for safety), annealed glass (standard glass), or other specialized types depending on the desired properties of the final product.
  • Interlayer: The invisible hero holding everything together. Here’s a breakdown of common interlayer materials:
    • Polyvinyl Butyral (PVB): The most widely used interlayer, offering a good balance of adhesion, clarity, and UV resistance.
    • SentryGlas® (ionoplast): A premium choice known for exceptional clarity, superior strength, and heightened safety compared to PVB.
    • Ethylene Vinyl Acetate (EVA): A cost-effective alternative to PVB, gaining popularity for its fast processing times and good adhesion properties. However, EVA may have slightly lower UV resistance compared to PVB.

A World of GLU Types:

The type of GLU is determined by its purpose:

  • Safety Glass: The workhorse, utilizing PVB or EVA interlayers to hold shattered glass together, minimizing injury risks.
  • Security Glass: Fortifies buildings against break-ins. Often uses thicker PVB, SentryGlas®, or EVA interlayers for superior strength and may even offer ballistic protection.
  • Hurricane Glass: Engineered for regions prone to severe weather. Utilizes thicker glass plies and robust interlayers (typically PVB) to withstand powerful winds and debris.
  • Decorative Glass: Integrates decorative films or fabrics within the interlayer, transforming a functional element into a design statement. Both PVB and EVA can be used for decorative purposes.
  • Soundproof Glass: Employs specialized interlayer materials (often PVB with acoustic properties) to significantly reduce noise transmission, creating a quieter environment.

Unlocking the Value of GLUs:

  • Enhanced Safety: GLUs prevent catastrophic shattering, minimizing the risk of injuries from falling glass.
  • Elevated Security: Increased resistance to forced entry compared to single-pane glass, offering peace of mind.
  • Improved Soundproofing: Specific GLUs significantly dampen unwanted noise, creating a more serene atmosphere.
  • UV Protection: The interlayer helps block harmful UV rays, protecting people and furniture from sun damage.
  • Design Versatility: Decorative GLUs add a unique touch to any space, incorporating aesthetics alongside functionality.

Choosing the Right Lamination Method:

  • PVB Lamination: The traditional and versatile choice, offering excellent performance in most applications.
  • EVA Lamination: A cost-effective option with faster processing times, well-suited for high-volume production and some architectural applications. However, consider the slightly lower UV resistance compared to PVB.

Applications for GLUs:

  • Architectural glazing (windows, doors, curtain walls)
  • Skylights and overhead glazing
  • Shower enclosures and partitions
  • Bullet-resistant glazing
  • Architectural and decorative applications (laminates with colored films or fabrics)

GLUs: A Wise Investment

By understanding the composition, types, applications, and benefits of GLUs, you can make informed decisions when specifying glass for your architectural, safety, or design needs. GLUs offer a powerful combination of safety, security, functionality, and aesthetics, making them a valuable investment for any project.
