Glass plays a crucial role in architecture and interior design, influencing not only the aesthetics of buildings but also their energy efficiency. There are various types of glass, each with unique properties tailored to specific needs. In this article, we will explain the differences between Low-E, ESG, and Float glass, helping you choose the best option for your project.
For a more detailed explanation of different glass types, check out this article: How to Differentiate Glass Types for Our Needs
1. Low-E Glass – Energy Efficiency and Thermal Comfort
Low-E (low emissivity) glass is a thermally insulated glass coated with a thin layer of metal oxide. This coating reduces heat loss and improves the building’s energy efficiency.
Benefits of Low-E Glass
Reduces heat loss in winter and keeps interiors cooler in summer
Blocks harmful UV rays, preventing furniture from fading
Helps save energy by reducing heating and cooling costs
Ideal for insulating glass units, facades, and glass doors
Using this type of glass can significantly increase a property’s value due to its energy efficiency and aesthetic appeal. Read more about how glass impacts real estate value here: Glass Increases Your Estate Value
2. ESG Glass – Safety and Durability
ESG glass (Einscheiben-Sicherheitsglas) is a tempered glass, thermally treated to be 4-5 times stronger than regular glass. This type of glass is primarily used in areas where safety and durability are crucial.
Benefits of ESG Glass
Enhanced safety – when broken, it shatters into small, blunt pieces, reducing the risk of injury
High resistance to temperature variations and sudden temperature changes
Used for railings, shower enclosures, facades, furniture, and automotive glass

3. Float Glass – The Foundation of the Glass Industry
Float glass is the most common type of glass, manufactured by floating molten glass on a thin layer of liquid tin. This process creates a perfectly smooth, transparent, and uniform glass, which serves as the foundation for most processed glass products.
Characteristics of Float Glass
Perfectly flat surface and excellent optical clarity
Used as raw material for tempered (ESG) or laminated glass
Available in different thicknesses, depending on the application
Float glass is essential in industrial processing and serves as the basis for many advanced glass products, including insulated, laminated, and painted glass.
Which Type of Glass Should You Choose?
- For energy efficiency and thermal comfort → Low-E Glass
- For safety and durability → ESG Glass
- For versatile and processable raw material → Float Glass
