window double glazing cost

The labour costs of installing double-glazed glass are around $70 to $100 per hour. This is just the cost of hiring a glazier and does not include the cost of materials.

The figures quoted above are just a rough estimate and may still change depending on several factors. Labour costs differ depending on your location.

The labour costs of double-glazing also depend on the style of your windows. Asymmetrical windows are harder to work on, and a glazier may charge more for working on them.

Installations during weekends or holidays may also cost more because glaziers charge more for working outside of their regular workdays and work hours.

 What Is Double Glazing?

Double glazing is a term that refers to making windows composed of two panes of glass. The central part of a double-glazed window is known as an insulated glass unit (IGU) .

The IGU is made of two glass panes. The two sheets of glass have an air gap between them. This gap gets filled with an insulating glass or a floating glass.

The insulating glass in the middle is why a double-glazed glass is better for insulation and soundproofing.

Double glazing is an excellent alternative to laminated glass if you want to soundproof windows. Laminated glass is cheaper. Double glazed windows cost more but have better noise reduction properties.

Some manufacturers use argon as filler. Double glazed argon-filled glass cost more but have better heat retention compared to cheap double-glazed doors and windows.

Double-glazed windows and doors are the most common types that you’ll see, double glazing is also useful for other parts of the house. Some glaziers use double glazing for skylights.

 Benefits of Double Glazing

Better Heat Management

Double glazing windows and doors can help keep a house warm during the winter. The insulating properties of double-glazed windows and doors can help trap artificial heat inside a house.

When you use a radiator or have heated floors, you will notice that the heat they produce eventually diminishes. This is because heat can escape through windows. The cold from outside the house also comes inside.

The upfront cost of using internal double-glazed windows might be high, but utilities’ long-term savings will even out the price.

Added Safety and Security

Double-glazed glass is more durable compared to regular glass. This means that UPVC double-glazed windows are more rigid and offer more security compared to single-pane windows.

The use of UPVC double-glazing or a double windowpane is an excellent choice if you’re planning to replace an existing window in an area that’s vulnerable to intrusion.

Double glazing is also ideal for a window or a sliding door if you live in an area that frequently experiences extreme weather conditions.

A double-glazed window might also be better for your family’s health, it can prevent the build-up of condensation. This, in turn, can help prevent the growth of mould, which might lead to health problems for you and your family.


Double-glazed glass is vital if you live in a busy neighborhood or near a high-traffic road. Having your windows double-glazed can help reduce noise so you can sleep better.

Internal double-glazed windows can help make a room soundproofed against noises coming from inside your home. If you want to have a quiet home office, then double glazing is what you need.

 How much do double-glazed windows cost?

The cost of double glazing is around 30-40% more than single-pane windows. The price difference is because double-glazed windows use more materials.

On the average, double glazed or dual pane windows cost from as low as $200 per square metre to as high as $1,400 per square metre.

The cost of double-glazed windows will depend on several factors:


A double-glazed sliding window’s price or a double-glazed sliding door’s price depends on how big the window or door is. Bigger doors and windows mean more glass.

However, some tradies give discounts. Bigger jobs often allow customers to negotiate with tradies to get more favourable prices.

Glazing Styles

A double-glazed window’s price will also depend on the glazing style. A UPVC double-glazed window is cheaper compared to an argon-filled double-glazed window.

Window styles will also come into play. Irregularly-shaped windows will require unique cuts that are more difficult for glaziers to execute.

When double-glazing for soundproofing purposes, secondary glazing comes into play. A thicker space between two panes will cost more since the insulating glass will also be thicker.

Type of Materials Used

This is one of the most significant determining factors in a double-glazed window’s price. The thickness of the glass will play a huge role in how much double-glazing costs. Thicker glasses will cost more.

However, it is important to note how long double-glazed windows last rely on the glass’ thickness. Thicker and sturdier glass will cost more but will also last longer.

The colour and materials of the frame also affect how much windows cost. Wood, metal, and PVC frames have different costs, so double-glazing patio doors prices will differ depending on the frame used.

The cost of replacing double-glazed window glass is lower than installing new ones. This is because replacement double-glazed window units often do not require new frames.

Double-glazed window glass replacement costs less depending on the location of the window. Windows on a high floor that requires the use of additional equipment will cost more to replace.
