Tip: When selecting architectural glass, it’s important to balance functional needs like safety and energy efficiency with the aesthetic vision for the space. Customizing glass to suit specific project requirements can improve both the building’s appearance and performance.
Annealed glass, also known as float glass, is the most basic form of architectural glass. It is created by cooling molten glass slowly, which results in a smooth and uniform sheet. While it is simple to work with and cost-effective, annealed glass can break into large, sharp pieces, which limits its use in areas where safety is a concern. It often serves as the base material for other glass treatments and modifications. Its ability to be easily cut and shaped makes it a reliable choice for non-safety-sensitive applications, such as standard windows or picture frames, where safety is not the primary concern.
Tempered glass is created by heating annealed glass to a high temperature and then cooling it quickly. This rapid cooling process strengthens the glass, making it up to five times stronger than regular float glass. When tempered glass breaks, it shatters into small, blunt pieces rather than sharp shards, making it much safer for environments where human safety is a concern. Because of its enhanced strength and safety features, tempered glass is ideal for high-traffic areas or locations where glass may be exposed to frequent impact, such as glass doors, shower enclosures, and storefronts. It is commonly used in automobile windows, where safety is a top priority, to prevent injuries in case of an accident.

Insulated glass units (IGUs) consist of two or more panes of glass separated by a sealed air or gas-filled space. This design enhances the glass's thermal performance, improving energy efficiency by reducing heat transfer. The air or gas in the sealed space acts as an insulator, helping maintain comfortable indoor temperatures while reducing the need for heating or cooling. IGUs also help to minimize noise transmission, making them an excellent choice for residential homes in noisy environments or commercial buildings situated on busy streets. The space between the panes of glass also helps reduce the amount of condensation, improving the overall durability of the windows or facades in which IGUs are used.
This type of glass is commonly used in residential windows, curtain walls in commercial buildings, and high-rise apartment complexes. The ability to reduce both heat transfer and noise makes IGUs essential in creating energy-efficient, comfortable indoor environments.
Low-E Glass: Low-emissivity (Low-E) glass features a thin, invisible coating that reflects infrared radiation while allowing visible light to pass through. This helps improve energy efficiency by preventing heat loss in winter and blocking excess heat in summer. Low-E glass is commonly used in residential windows, office buildings, and other structures that require enhanced thermal control.
Smart Glass: Smart glass can dynamically change its transparency in response to external conditions, such as light or temperature. This ability helps control privacy, light levels, and interior temperatures, making it an ideal solution for modern buildings looking to adapt to changing environmental conditions. Smart glass is often used in offices, conference rooms, and luxury homes where light control and privacy are critical factors.
Low-E glass is ideal for buildings aiming for energy efficiency and those in regions with extreme temperature variations. Smart glass, with its adaptability, is perfect for modern architecture where sustainability and comfort are prioritized.
