The Ultimate Guide to Toughened Laminated Glass

May 30, 2024

In the manufacturing and construction industry, glass is widely used for home design and improvement projects.

Among the myriad of glass options available, toughened laminated glass stands the test of time. This serves as a top choice for many designers due to its remarkable strength, durability, and versatility.

Today, TuffX will dive into the specifics and benefits of toughened laminated glass and its prevalence in the home.

What is Toughened Laminated Glass?

Toughened laminated glass is composed of two or more layers of glass that are bonded together with one or more interlayers of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA).

The individual glass sheets are heated to 620 °C and then rapidly cooled. This makes it five times stronger than untreated glass. After this tempering process, the glass sheets are cleaned and assembled with one or more interlayers of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA).

This is then subjected to heat and pressure in an autoclave, bonding the layers to create a single piece of glass. After lamination, this glass can be cut and finished for various applications.

The Strength of Toughened Laminated Glass

Toughened laminated glass is regarded highly for its exceptional strength. This makes it a widely used material for demanding applications in residential and commercial settings.

The factors that influence its strength include:

  • Impact resistance: When struck by a heavy object, the glass cracks without shattering as the interlayer holds the pieces together.
  • Thermal resistance: The tempering process increases its ability to withstand extreme temperatures without compromising its structural integrity.
  • Load-bearing capacity: This type of glass can bear heavy loads without bending or breaking, making it reliable in high-traffic areas.
  • Durability: The tempering process increases the glass’s resistance to physical stress. This means it can withstand substantial force without breaking.

The Safety Benefits of Toughened Laminated Glass

Toughened laminated glass is often used by architects and builders for various public structures. This is due to its wide range of safety benefits and long-lasting durability.

These safety benefits include:

  • Bullet and blast resistance: Toughened laminated glass can be designed to withstand bullets and blasts without disintegrating.
  • Fire resistance: Specialised interlayers can be incorporated into this glass to prevent the spread of flames and smoke.
  • UV protection: The interlayer in this type of glass can block up to 99% of harmful UV radiation, reducing damage to residents and the building itself.
  • Acoustic insulation: The interlayer in toughened laminated glass dampens sound vibrations, reducing noise pollution. This enhances safety in hospitals and situations where low noise disruption is essential.
  • Shatter resistance: Unlike standard glass, which breaks into large, sharp shards, toughened laminated glass is designed to hold together when shattered. This reduces harm to pedestrians during accidents.

Style and Design Flexibility

There are a variety of customised options for toughened laminated glass, allowing you to achieve the desired look for your application. Some popular aesthetics include:

  1. Clear, toughened laminated glass: This provides a clean and modern look and is ideal for windows, partitions, and doors.
  2. Tinted, toughened laminated glass: Tinted glass provides a layer of privacy and reduces glare, making it perfect for skylights and facades.
  3. Frosted, toughened laminated glass: This provides diffused light while maintaining privacy and is often used in bathrooms, decorative panels, and office partitions.
  4. Patterned and textured toughened laminated glass: This comes in a range of patterns for an appealing look, perfect for decorative applications.

Applications of Toughened Laminated Glass

This type of glass is widely used for various residential, commercial, and speciality applications. This includes:

  • Windows and doors
  • Balustrades
  • Skylights
  • Storefronts
  • Balconies
  • Public buildings
