Not all glass is created equal. From the glass you’d find on your car windscreen to the glass on your office windows – the construction and material differ depending on the purpose.
Knowing what type of glass you have will ensure it’s fit for use. Plus, when it comes to cleaning your windows, you’ll be able to select the right products and methods to suit.
While there are many different types of glass, there are 3 types that are most commonly found in residential or commercial buildings.
Here is an overview of the 3 different types of glass you need to know about.
Float glass is a low-cost, energy-efficient glass that is commonly used in high rise buildings as well as the automotive industry for windscreens. A popular feature of float glass is that it reduces outside noise, which is why it’s commonly used in a residential setting.
Float glass consists of sand (60%), dolomite lime (20%) soda sulfate (20%) as well as recycled cullet glass. The production line stretches anywhere up to half a kilometre long, manufacturing anywhere up to 6,000 kilometres of glass every year. The thickness of float glass varies between 0.4mm and 25mm and can be up to 3 metres wide.
Low-E stands for low emissivity. Low-E glass contains a thin, microscopic coating on the inside which gives it thermal efficiency properties. The result reduces the transfer of heat from the property to the outside, making the building more energy-efficient in colder weather. This system also works in reverse, so that in the summer warm air does not transfer into the home, which would make the room too warm.
There are two types of Low-E glass called hard coat (pyrolytic) and soft coat (sputtered). Usually, hard coat also known as pyrolytic Low-E coating is used within double glazed windows. The advantages of being it can be exposed to the air and cleaned with traditional products. Sputtered Low-E glass is often used within single glazed windows, though does not offer the same level of energy efficiency or security.
Glass can be incredibly dangerous when it shatters, which is why toughened glass needs to be used in certain situations where human impact is likely. For example, the likes of shopfronts, frameless glass doors, overhead glazing and shower enclosures. If broken, toughened glass crumbles into small pieces rather than large fragments to reduce the risk of injury.
The process of making toughened glass involves it being heated to 600°C where it is then rapidly cooled. This causes the surface of the glass to contract, creating a strong outer layer. Toughened glass is then much more resistant to temperature changes and impact stress, which is why it’s a popular choice for manufacturers.
