With numerous options available in the market, it can be overwhelming to determine which type of glass will best suit your specific requirements. In this blog post, we will guide you through the different types of glass available and help you make an informed decision.

1. Float Glass

Float glass is a popular choice for various applications due to its versatility and affordability. It is manufactured by pouring molten glass onto a bed of molten tin, resulting in a sheet that has a uniform thickness and a smooth surface. Float glass is commonly used for windows in both residential and commercial buildings. However, it is important to note that float glass is not as strong or energy-efficient as other types of glass, making it less suitable for applications that require enhanced safety or insulation.

2. Tempered Glass

Tempered glass is designed to be stronger and more resistant to breakage than regular glass. This type of glass is manufactured using a process called tempering, which involves heating the glass to a high temperature and then rapidly cooling it. Tempered glass is considered to be safety glass, as it shatters into small, granular pieces when broken, reducing the risk of serious injury. It is commonly used for applications that require enhanced strength and safety, such as glass doors, shower enclosures, and automobile windows.

3. Laminated Glass

Laminated glass is made by sandwiching a layer of polyvinyl butyral (PVB) between two or more layers of glass. This layer of PVB acts as a bonding agent, holding the glass together even when it breaks. Laminated glass provides increased safety, as it remains intact even when shattered, preventing shards of glass from causing harm. It is often used for applications that require security, such as storefronts, banks, and hurricane-resistant windows. Laminated glass also offers enhanced noise reduction and UV protection.

4. Low-E Glass

Low-emissivity (Low-E) glass is a type of coated glass that helps to improve energy efficiency in buildings. This type of glass has a thin, transparent coating that reflects heat while still allowing visible light to pass through. By reflecting heat, Low-E glass helps to keep interiors cool in summer and warm in winter. This can result in lower energy consumption and reduced utility bills. Low-E glass is commonly used for windows in energy-efficient buildings or in regions with extreme climates.

5. Insulated Glass Units (IGUs)

Insulated glass units, also known as double-glazed windows, consist of two or more glass panes separated by an air or gas-filled space. This construction provides better insulation compared to single-pane windows, reducing heat transfer and improving energy efficiency. IGUs can help to reduce energy costs, minimize condensation, and provide noise reduction benefits. They are commonly used in areas where thermal insulation is important, such as residential homes, offices, and hotels.


Choosing the right type of glass for your replacement needs requires careful consideration of your specific requirements and priorities. Float glass is a budget-friendly option for standard applications, while tempered glass offers enhanced strength and safety. Laminated glass provides both safety and security, whereas Low-E glass helps to improve energy efficiency. Finally, insulated glass units offer superior thermal insulation and noise reduction benefits. By understanding the characteristics and advantages of each type of glass, you can make an informed decision and select the most suitable option for your replacement needs.
