The cost of double glazing windows
Double glazing. It’s effective for keeping your home warm in winter and cool in summer. It reduces your power bill and it’s great for the environment. Outside sound doesn’t travel through your home as fast and your windows are harder to break into.
This all sounds great, right? But how much does double glazing cost? If you like the benefits of double glazed windows and doors, but you’re not sure whether you’re ready to make the investment, this article is for you.
Let’s get started.
The cost of double glazing windows
First of all, we’ll start by saying there’s no one simple answer. Just as no two homes are the two, no two double glazed windows and doors are either.
That’s why it’s hard to say exactly what your double glazing will be, without seeing your home. This article is designed to give you a ballpark figure and let you know the components that affect the price of double glazed windows.
Typically, double glazing units won’t often fit to existing windows, so instead they’re replaced entirely. As an estimate, it costs around $800 per square metre.
Then there’s secondary glazing, which is easily added to your existing window. This can cost between $400-500 per square metre. This option is ideal for homeowners who want an effective solution to noise and insulation problems.
What factors affect double glazed windows price
A number of components will affect the cost of double glazing windows.
Factors such as:
The different types of windows
The size of the windows
Installation and labour.
As you can see, the double glazed windows cost aren’t standard. You might like the design of a European tile and turn window, over a traditional awning style. You might favour the oyster white over a unique annodised finish. Your home could be by the ocean, so salt water resistant windows and doors are more important to you than noise reduction.
There are different types of glass, offering a range of thermal and noise efficiency. There’s toned glass, low emissivity glass, laminated glass, insulated glass units (IGUs), and secondary glazing.
The same goes for frames. They also come in a range of options, including aluminium frames, timber frames, composite frames, and uPVC. Then there are frame styles, such as casement, sliding, awning, double hung, two panel sliding door, and louvre.
In terms of design considerations, there’s thermal mass, noise control, fading, and condensation. Double glazing will be custom made to meet your needs. If you live close to a highway or busy road, sound efficiency is much more important than if your home is on a quiet, suburban street.
Just like the double glazing windows cost differs, the impact will too. You will need to consider things like:
Climatic conditions in your location: temperature, humidity, sunshine and wind
Building design: the orientation, form and layout of the building
Building materials: the amount of mass and insulation
The size and location of windows and shading
Thermal properties of glazing systems.
Save up to 25% on your electricity bill
Think of a double glazed unit as a speed hump for air, prompting it to slow down. You’re never going to stop the transfer of air through a surface, but with thin glass (3mm, in single glazing), it travels faster.
Double glazing is made up of two pieces of glass that have a spacer between. The exterior silicone is also sealed. As a result, the outside air has to penetrate the outer layer of glass, continue through the air between the unit, then travel through the inner layer of glass. It takes longer, so your air inside stays warmer, for longer.
Expect to save up to 25% on your quarterly power bill, by installing double glazed windows. Within five years (depending on your energy use), you will regain the cost of investing in double glazing.
It’s best to look at the double glazed windows cost as rather a long-term investment. Double glazing will make your home more comfortable now, and more efficient over the coming years.
The cost of energy is only going to rise, so get in now and safeguard your home. If you’re still sitting on the fence and you’re worried about the initial outlay, consider replacing single glazed windows with double glazed in rooms where you want natural light. Take your kitchen for example. You spend a lot of time in there and natural light does wonders to prevent overheating.
Think of double glazing as an investment – one which will always pay off. A report by the Australian Bureau of Statistics uncovered some interesting facts about uPVC window cost.
The report explained that across the range (0-10) of EER star rating, an increment of 0.5 amounts to a consistent 1.2% increase in house price. Long story short? Double glazing not only reduces your power bill, but it adds to your house value too.
Say for example, you spend $10,000 on double glazing. This would raise the value of your $400,000 home by 2.4% - that’s $9,600. See, double glazing pays for itself simply in added sale value.
