Can Both Laminated and Tempered Glass Be Used in Exterior Applications?


Glass is a fundamental material in architecture, offering not just transparency and natural light but also contributing to the aesthetic and functional design of a building. Among the various types of glass, laminated and tempered glass stand out for their unique properties, making them suitable for a wide range of exterior applications. This article delves into whether both laminated and tempered glass can be used in exterior applications, examining their characteristics, advantages, and suitability for different architectural needs.

Understanding Laminated Glass

Laminated glass consists of two or more glass layers bonded together with an interlayer, typically made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This composition enhances its safety, acoustic insulation, and UV protection properties. Commonly used in car windshields, laminated glass is also prevalent in exterior building applications, such as skylights, balustrades, and facade glazing, providing both safety and energy efficiency.

Exploring Tempered Glass

Tempered glass, known for its strength, is created by heating glass to a high temperature and then rapidly cooling it, a process known as tempering. This treatment significantly increases its strength and changes its breakage pattern, making it safer than regular glass. Tempered glass is widely used in exterior applications like doors, windows, and curtain walls due to its durability and resistance to environmental stresses.

Comparative Analysis: Laminated vs. Tempered Glass

When comparing laminated and tempered glass for exterior applications, several factors come into play, including safety, energy efficiency, and aesthetic preferences. Laminated glass offers enhanced safety features due to its ability to hold together when shattered, reducing injury risk. Tempered glass, on the other hand, excels in strength and thermal resistance, making it ideal for areas exposed to temperature variations and physical impact.

Safety Considerations and Building Codes

Both types of glass are subject to building codes and standards, which dictate their use in exterior applications. These regulations ensure that the glass used in buildings meets safety, durability, and energy efficiency requirements, guiding architects and builders in their selection process.

Innovations in Glass Technology

The glass industry continues to evolve, with innovations in both laminated and tempered glass offering improved performance and new applications. These advancements include enhanced thermal insulation, self-cleaning properties, and increased resistance to impact and weather conditions, broadening the scope of their use in exterior applications.

Environmental Impact and Sustainability

Sustainability is a growing concern in construction, and the glass manufacturing process is under scrutiny for its environmental impact. Both laminated and tempered glass have pathways to sustainability, including recycling initiatives and the use of eco-friendly materials in their production processes.

Case Studies: Successful Exterior Applications

Numerous iconic buildings and innovative projects showcase the successful use of laminated and tempered glass in exterior applications. These case studies highlight the versatility and performance of these glass types in achieving architectural visions and functional requirements.

Maintenance and Longevity

Proper maintenance is crucial for the longevity and performance of exterior glass. This section provides care tips and highlights the factors affecting the long-term durability of laminated and tempered glass in exterior settings.

Choosing the Right Glass for Your Project

Selecting the appropriate type of glass for an exterior application involves considering several factors, including safety requirements, aesthetic goals, and environmental conditions. Expert advice and a comprehensive understanding of laminated and tempered glass properties can guide this decision-making process.



Both laminated and tempered glass offer distinct advantages for exterior applications, making them suitable for a wide range of architectural projects. Understanding their properties, applications, and compliance with safety standards is essential for architects, builders, and homeowners looking to make informed decisions about glass usage in exterior designs.
