Glass is just glass, right? Not exactly. In fact, there are several different types of glass out there. It’s more than just looks—each one is manufactured differently and designed to perform a specific purpose. And if you’re looking for a high-performing all-purpose glass, it’s time to look into float glass.

If you’re in the market for glass for business or commercial buildings, here’s a look at the unique properties of float glass and what it can do for you.

What is Float Glass?

Float glass, sometimes called flat glass or clear glass, is one of the most common types of glass, characterized by a greenish nuance.

The term “float” comes from the manufacturing process. Float glass is manufactured on a float line, where the manufacturer floats liquid glass over a bed of molten tin to create molten glass. Because tin has greater density, the liquid glass mixture floats on the top to form a pool of molten glass. As the glass shifts onto ceramic conveyors and solidifies, it can be treated and cut for shipping.

Float glass that has not been tempered heat-strengthened is called annealed glass. Annealing is a process of controlled heating and cooling during glass manufacturing and the first step of architectural glass production. Annealed glass is allowed to cool slowly to room temperature, while tempered glass undergoes a different heat treatment followed by rapid cooling.

Properties of Floating Glass

Floating glass is one of the most common types of glass used in construction today. In fact, the majority of flat glass is float glass.

The glass itself is made from calcium and sodium silicate, which is where it gets the nickname soda-lime glass. Because of its chemical composition, it tends to break into large, serrated spikes, and it has a characteristic greenish nuance when viewed in the light, though it can be made to have any color you’d like.

It’s often called flat glass because the floating process ensures that all float glass is made in flat panes. Without any additional treatment, it’s a clear glass with a high transmission degree known for its naturally high optical clarity, though it can be easily modified for opacity in the manufacturing process.

Advantages of Float Glass

There are several advantages to float glass that make it a popular construction material.

First and foremost, the material is cheap and widely available. It’s relatively easy to make, so you can easily find float glass installation for a reasonable price.

Second, conventional float glass is an excellent choice for windows due to its high optical clarity and high light transmission. But it’s also quite robust against scratches, which means it ages well.
