DIFFERENT TYPES OF WINDOW GLASS

Different Kinds of Window Glass

Choosing the right type of glass for a window glass replacement can be an overwhelming process due to the vast amount of choices available. Glass manufacturing has come a long way in the last 20 years and these days there is a different type of glass for every application you can think of from reducing sun glare, to helping heat and cool your home, and even glass which prevents injury when it is accidently shattered.
To help make the process easier for our customers, we’ve listed the most common types of glass installed in homes throughout Australia –

Float Glass

Float glass or glass that has been annealed is a basic flat glass product. It is what is obtained initially during the overall process of manufacturing glass. During this production process, annealed glass goes through a slow process of cooling under conditions that are controlled. This procedure of annealing removes all the internal stresses in the glass.

Benefits of Float Glass

  • Cost-effective
  • Light transmission is outstanding and has a clear tone
  • Various options and tones are available
  • Visibility is outstanding
  • It has a surface strength that offers performance against wind-load and the resistance to thermal stress that is required in architectural applications

Toughened Glass

Toughened glass is also known as safety glass or tempered glass. Australian Standards classify it as Grade A safety glass. Toughened glass is also one variety of annealed glass. Heating of this glass is done in a furnace, after which the glass is cooled rapidly. Because of this toughening process the risk of cracking is lowered. Compared to standard annealed glass, toughened glass of a similar thickness is five times stronger. The purpose of providing toughened glass is to reduce the chances of it causing injuries when it is broken by any human impact.

Benefits of Toughened Glass

You can get it in many tones and opaque options
Ideal for use in large openings
Physically and thermally stronger than regular glass
Safer – When this glass breaks, it never breaks into shards, but into tiny pieces that are not as dangerous
Suitable when important considerations are strength, thermal resistance and safety

Laminated Glass

This is glass that is made of two layers of sheet glass that have a permanent bonding through an interlayer that improves acoustics and impact resistance, and is also called safety glass. When the glass meets the relevant standards, this laminated glass has a classification of Grade A safety glass.

Areas of a home that are prone to get damaged by human impact like in bathrooms, or full length doors and windows are better glazed with laminated glass. It is glass that is best used where you need additional security, UV protection, sound reduction, and energy efficiency.

Benefits of Laminated Glass

Outside sounds can be minimised with the use of laminated glass that has an acoustic rating
Safer- When the glass breaks, the fragments stay remain bonded to the interlayer in the panel, and will not break into shards that can be a danger
Standard laminated glass improves the protection to kitchen benchtops and furnishings that can fade due to exposure to UV rays
Low-E Laminated glass reduces by 30%, the heat conducted by it as compared to annealed glass. It also reduces glare and improves thermal efficiency

Low-E glass

Low-E Performance Glass has a coating that permits natural light to go through without it emitting any radiant heat, and this helps in maximising light and energy efficiency. It is a glass that sees use where there is need for greater solar and thermal control and in spaces that are not naturally heated. It is an option that needs to be considered for the Energy Efficiency Ratings of new homes, especially in those where you desire to have plenty of light.

Benefits of Low-E Glass

Improved insulation and greater solar control is provided when tints are used for all year long comfortable temperatures inside a home
Availability in a wide range of tones
The rate of furniture fading is reduced as this glass absorbs UV radiation

Double Glazing

Double glazing has two panes of glass that are sealed after they are separated by a layer of air or argon gas. An insulation barrier is created by the argon gas that is more effective in comparison to air and helps to reduce heat flow through glass and its thermal conductivity. Jason windows only makes use of argon gas in their products that are double glazed.

The thermal benefits that double glazing brings makes it perfect for windows of rooms where you want to have greater control over gains and loss of heat through windows.

Benefits of Double Glazing

Energy costs are reduced by their outstanding insulation performance, especially when combined with a low-e coating.

The right glass combinations in an IGU can significantly reduce noise pollution

Humid air condenses on a glass surface that is cold, but this is reduced when double glazing is used due to the air gap filled with argon
