Float Glass vs Tempered Glass: Which Is Best For My Home?

float glass vs tempered glass

There is a lot more that goes into crafting residential and industrial windows than most people realise.

When you scratch away the surface, you reveal a vast range of different window types and crafting methods, drawing up questions like, which is best in the debate between float glass vs tempered glass?

With all the different types of glass on the market, there is a substantial variance in quality and performance. Window systemsthat look the same, are very unlikely to perform the same, with some shocking differences in quality and construction.

The ability of a window to perform exceptionally, all starts with the type of window, and what its designed to do.

This difference can be seen very clearly in the float and tempered glass debate, with both types of glass offering different advantages and disadvantages to a property.

If you’re looking to upgrade the windows in your home, and try to combat those rising energy bills, then it’s likely that you’ll come across the issue at some point or another: of which is better: tempered glass or float glass.

So, which is really best? Let’s take a look at what both glass types in turn, and discern what they have to offer your home…

What Is Float Glass?

Float glass is a really interesting and common glass type, made using incredible techniques that can produce exceptionally flat and highly appealing glass panes. This involves a controlled form of cooling, where the glass is created in such a way that it is exposed to minimal stress.

The glass is made in a process that sees molten glass floated on molten metal, allowing it to form a consistent thickness and flat surface. Due to the exceptional results, this is a common method for making the glass used in most residential properties.

Advantages

  • High-quality finish
  • Very clear glass and flat surface
  • Multiple options for different thicknesses

Disadvantages

  • Not as strong as tempered glass
  • Breaking the glass leaves sharp shards of glass that can compromise safety

With each type offering such different benefits, and sadly disadvantages, it can be worthwhile getting the best of both worlds. This is something that most triple-glazing window systems are offering – two sheets of float glass, with an internal pane of tempered glass

What Is Tempered Glass?

Tempered glass is not so much a way to construct glass, but a way to enhance its performance in some areas. Due to this, tempered glass can actually be float glass, but is quite different in performance, appearance, and use.

This almost turns the float glass vs tempered glass debate, into float glass vs a different kind of float glass.

To make tempered glass, the float glass is heated up, to around 600c, before being rapidly cooled down again. This puts a lot of stress on the pane of glass, making it stronger, and changing the way that it acts when force is administered. This can make it safer, stronger, and more energy-efficient.

Advantages

  • Lowered chance of thermal breakage
  • Great for insulation
  • Controlled breaking where the fragments are small and cubic
  • Up to 5x more strength than float glass

Disadvantages

  • The fragmented shattering can affect security
  • Impossible to work with after toughening
  • The edges of the glass are susceptible to easier damage
  • Lower visibility

Which Glass Type Is Best?

Each glass type, float and tempered, offers something a little different; these two prove to be greatly contrasting options. Tempered glass is harder to break, but poses more of a security risk when it is broken.

In contrast, float glass is much easier to break, but the sharp shards of glass are going to cause big problems for any potential intruders.

With each type offering such different benefits, and sadly disadvantages, it can be worthwhile getting the best of both worlds. This is something that most triple-glazing window systems are offering – two sheets of float glass, with an internal pane of tempered glass.

These window systems make for fantastic standard windows, but also great additions to doors, like the high-security composite door.
