The types of glazing and what is best

With an overwhelming range of glazing types on the market in Sydney, we know how confusing it can be to know which is right for your project. Glazing comes in various thicknesses, energy performance enhancements, colour tints and decorative films, so we’re here to find you the appropriate solution for your project.

What Glass Is Best For Thermal Protection?

As windows do no have a great thermal performance in comparison to solid walls, most glass manufacturers are working towards technological advancements to make windows more sustainable and energy efficient.

Reflective glass

This is glass that has been treated with a metallic coating to help reflect heat and radiation rather than absorbing it. Reflective glass reduces heat gain and visible light transmission. There are two methods that are used to do so, colour tints and reflective films.

Low-Emissivity (Low-E) Glass

This is glass that has a special invisible coating to reflect and block out heat, all while minimising UV rays from passing through the glass.

Reflective films

This involves a reflected film that is applied to one side of the glass to decrease solar gain. This in turn reflects more light and often has a mirror effect.

Colour tinted glass

This is glass with small colour additions such as bronze, green, blue or grey. It can help to regulate solar heat gain by absorbing the heat. The colour is homogenous throughout the expense of glass and will not affect the basic properties of the glass itself except for solar energy transmission.

Safety glazing options for window walls

When designing a Sydney window wall system you must also consider its safety. As we know, glass is sharp when it is broken, therefore there are ways to minimise hazards associated with glass breakage, using tempered and laminated glass options.

Laminated Glass

This safety glass holds itself together when it is broken or shattered. It has a special interlayer that sticks between the glass layers.

Tempered Glass

This is a type of safety glass that is stronger both physically and thermally to normal glass. When this type of glass is broken it shatters into granular pieces instead of splintering into jagged shards of glass. The tempering process makes the outer surfaces into compression and the inner surfaces but tension. These granular pieces are far less likely to cause injury.

Decorative & Other Types Of Unique Glass

In addition to temperature regulating and safety options for window glazing, there are also a variety of decorative Sydney window options for privacy and other features. These are not standard or traditional window wall systems so you may need to request and enquire.

Electrochromic Privacy Glass

This glass can turn opaque or translucent with the flick of a switch (electrodes are installed to the inside of the glass and when an electric current runs through it, the ions react and move to reflect light). It is most commonly used for privacy reasons.

Translucent Glass

This is achieved with sandblasting, acid etching or applying a specific film to make the glass less transparent for privacy or decorative reasons.

Bird-Friendly Glass

This glass is patterned with a UV reflective coating. It is visible to birds but not to the human eye therefore it remains translucent to us.

Self-Cleaning Glass

This is glass that has a chemical coating that reacts with the daylight to minimise and break down organic dirt. It cleans itself via both daylight and rain.

The types of window glass and what is best for your home

While being an expert in glass isn’t necessary, it can be very helpful to understand common terminology and the different kinds of glass that are available in Sydney. Below is a comprehensive list of the many window glass types, so you can appropriately choose what’s best for your home or project in Sydney.

Tempered Glass

Tempered glass is annealed glass – only with quadrupled strength. Tempered glass can’t be cut, so the tempering process takes place only after the annealed glass is cut and finished in the desired size. The glass is heated to above 1200 degrees and then quickly cooled. To make heat-soaked tempered glass, the panes are baked at 550 degrees. The tricky thing is that if the glass happens to be unstable, it’ll break. This method tests the glass before it’s used in any real-life applications. You probably have tempered safety glass in your car, so that you can break them in emergency situations.

Wired Glass

Wire glass isn’t necessarily considered a security glass, but it’s a fire-resistant glass. It’s for this reason that it’s primarily used in schools, hospitals, and other commercial buildings. The grid of wires built into the panes will actually hold the glass in the frame if it shatters under high heat – such as a building fire. It can also withstand a blast from a firefighter’s hose without blowing shards out everywhere. While wired glass works great for many commercial applications, you don’t often see it used in residential home design.

Safety Laminated Glass

Laminated glass is an extra-strong, security-enhanced glass created by fusing at least two panes around an inner layer of PVB (polyvinyl butyral). This process uses a high heat and pressure fusion process to create a super-strong panel. If you need glass to stay put in the frame if it’s broken, for safety or security reasons, this would be one of your best choices. After all, it’s laminated glass technology that you’ll find in your vehicle’s windshield: ensuring that an object colliding with the glass does not strike the occupant and spray glass shards inside.

Obscured Glass

Obscured glass is any type of glass which allows light to come in, but can’t be clearly seen through. Obscured glass patterns may be frosted, etched, coated or otherwise designed so that you can’t look through it and see more than vague shadows of what’s behind. That’s why this is the most popular type of glass for bathroom windows, shower doors and entry door areas. While there’s some debate on whether it truly affords enough privacy for bathrooms and showers or not, obscured glass is typically sought after by people who want more natural light in their home.

Float Glass

Float glass is named for the process of forming molten glass into large, flat panels. During the process, molten glass is floated on molten tin, producing the smoothest possible large, thin glass panel. This is a basic sheet of glass before it is cut, treated, upgraded and set into a frame – a starting material for your window. Float glass is low-cost, colourless glass as the starting point for what will become quality windows, glass doors and panels.

Annealed Glass

Annealing is the slow, meticulous and controlled process of cooling a panel of float glass. The purpose of this process is to strengthen the glass by reducing the stress caused to it by quick cooling. This is usually the next step for float glass, and now further upgrades can be done. Annealed glass is not the ideal choice for windows, as it’ll leave shards and large, sharp pieces if it is broken.

Mirrored Glass

To create mirrored glass, a panel is given a metal coating on one side. This coating is sealed with an extra protective sealant, creating a mirror effect. You usually find mirrored glass being used in a decorative capacity, such as on walls, furniture and doors. Mirrored glass is pretty, but it’s not usually used for exterior windows.

Tinted Glass

Tinted glass is any kind of glass which has colouring added. This can be done for several reasons, including design aesthetic, privacy and reducing heat from sunlight. Tinted glass can also be a form of protection against harmful UV rays. You typically see tinted glass on vehicles, skylights and decorative panels, but you can also use it for external windows to improve your privacy.

Insulated Glass

Insulated glass windows come in a unit that is optimised for energy efficiency. They may be two or three panes of glass, with argon in the spaces between the panes. The glass panes in an insulated unit are typically laminated or tempered security glass. An insulated glass window unit also has a desiccant component, ensuring that condensation won’t form in between the panes where you can’t wipe it off. Insulated glass windows are an amazing choice for exterior glass that’ll help you reduce your heating and cooling costs. Not all insulated glass units are created equally, so compare your options for the best energy efficiency ratings.

Low-E Glass

Low emissivity glass is specially coated to reflect thermal radiation. The low-e coating keeps out infrared rays, while light still filters through. Why is this so beneficial for homes? During the summer, heat is directed away from your house, and in the winter, your indoor heat is reflected back in the house and won’t escape through the windows.

Heat Strengthened Glass

To make annealed glass panels twice as tough, it’s reheated above 1200 and then cooled. It’s not cooled quite as quickly as tempered glass, so it’s not as strong. Heat strengthened glass is tougher than lower grades of glass, but it can still shatter and break into sharp pieces. It’s not often used for exterior windows until it has also been laminated. This translates to lower heating and cooling costs. Low-e glass can be a pricey investment, but the savings in the long run can make it worth it. Some types of low-e coatings cause tinting, so be sure to check out some samples in person to make sure you’re okay with how the glass will look installed in your home.
