Tempered Glass Windows: A Guide To Strength, Safety And Easy Installation

In modern architectural design, glass plays an integral role in enhancing aesthetics and functionality. Among the various types of glass available, each offering unique features and benefits, tempered glass stands out for its incredible strength and safety.

Tempered glass is fabricated to provide remarkable safety and durability, making it a superior option for varied architectural applications. The different types of glass - like lacquered, frosted or tinted - can be tempered to enhance structural integrity.

Why Choose Tempered Glass for Windows?

Tempered glass undergoes a special heat treatment (tempering) process, that makes it significantly stronger than annealed glass. This process involves heating the glass to high temperatures followed by rapidly cooling it, thereby rendering it with remarkable strength.

Needless to say, among the most important applications of this robust glass are windows as they are a building's external safety barriers. Sealing and securing windows effectively is crucial to protect people and property from external impact. Thanks to its exceptional durable properties, tempered glass is ideal, and its compatibility with all types of frameworks, including UPVC, aluminium, and steel, makes it the preferred choice.

Advantages of Tempered Glass Windows

Unmatched Strength

Tempered glass is significantly stronger than standard glass, allowing it to withstand external forces such as wind, hail, or accidental impacts​. This incredible strength makes it perfect for large window installations. Read our blog about top 10 advantages of sliding glass windows.

Enhanced Safety

The primary advantage of tempered glass is that it is designed for safety. Despite its remarkable strength, in the rare event of breakage, it breaks into small, blunt pieces, therefore lowering the risk of injury.

Heat Resistance

Tempered glass can withstand high temperatures, maintaining its strength and performance even under extreme heat making it suitable for safety applications, such as reinforced windows for high-rise offices and apartment buildings.

Versatility

Most types of glass, such as solar control, tinted, or frosted, can be tempered to enhance durability, providing a wide range of design possibilities with added safety. Tempered glass can also be lacquered to add opacity and vibrance. Its strength allows for frameless installations, perfect for creating a modern, minimalist aesthetic​.

Installation Tips for Tempered Glass Windows

Tips for Tempered Glass Windows

Installing tempered glass windows requires meticulous planning and execution to ensure a flawless and safe result.

  1. Quality Check: To ensure the authenticity of the toughening process, look for Saint-Gobain’s logo followed by the authorised glass processing partner logo on the toughened glass.
  2. Inspect Glass Panels Carefully: Before installation, thoroughly inspect all tempered glass panels for scratches or edge defects. Even minor flaws can compromise the glass's structural integrity, leading to breakage during installation.
  3. Smooth and Precise Cutting: For tempered glass, opt for precise cutting in controlled factory settings to have smooth, polished cut edges and avoid breakage. The glass should be tempered post-cutting to the desired size and shape.
  4. Modifications only Before Tempering: All the processing, surface treatment etc need to be completed prior to the toughening or tempering process. Any modifications after the tempering process, like drilling or edge shaping, disrupt the internal balance of tempered glass, which can lead to breakage. 
  5. Snug fit into Frame: Ensure the glass fits perfectly within the UPVC or metal frame. The glass shouldn't move independently within the frame. Use tempered glass-specific hardware such as clips, brackets, or rubber gaskets to securely hold the glass in place without applying undue pressure.
  6. Handle with Care: Transport and handle tempered glass with care. Store the glass panels upright with sufficient padding along all edges to prevent damage. When handling large panes of glass, use suction cups for a better grip and reduced risk of dropping the glass.

Conclusion

Tempered glass windows offer a unique combination of strength, safety, and style, making them the perfect choice for modern homes and commercial spaces. Discover Saint-Gobain’s Tempered glass solutions for your next project to meet modern design and safety needs.

 

FAQs about Tempered Glass

What is tempered glass?

Tempered glass undergoes a controlled thermal treatment process that significantly increases its strength compared to ordinary glass. This treatment makes it more resistant to impact and temperature changes, enhancing its durability and safety.

Where is tempered glass commonly used?

Tempered glass is commonly used in a variety of applications, including doors and windows, partitions, glass tops for tables, railings, and areas that require security. Its strength and durability make it a popular choice for both residential and commercial projects.

What is the difference between tempered glass and regular glass?

Tempered glass is significantly stronger than regular glass due to a treatment process that involves heating the glass to extremely high temperatures and then rapidly cooling it. Also, in the unlikely event of breakage, tempered glass shatters into small, blunt pieces instead of sharp shards averting the risk of injury.

Can tempered glass be cut?

No, glass cannot be cut or drilled after it has been tempered. Any cutting, shaping or drilling must be done before the tempering process.
