Double Glazed Windows

Associations & Accreditations

How much heat are you losing in winter through your windows? How little air is allowed to pass through in summer? The reason behind your high energy bills are staring you right in the face every single day.

The single glazed windows in your home are perhaps the biggest energy drain, leading to over reliance on heating and cooling systems, in a time when energy costs are every increasing.

What do you do? Do you watch your energy bills get higher and higher and pay the price or do you eliminate the source of energy inefficiencies? Our advice?

It’s finally time for you to make the move to UPVC double glazed windows.

Why Double Glazed Windows?

Glass is naturally a good conductor of heat. Single glazed windows therefore offer poor insulation, not to mention minimal protection against high winds and noise levels. The difference when you make the move up to double glazed windows is simply phenomenal.

How can an additional pane of glass make such a difference? With double glazed window systems, a layer of air is trapped between the two panes.

Air is a poor conductor of heat so double glazed windows are able to slow down the passing of heat through the glass, ensuring a cooler environment during the hot Australian Summers and retaining heat when needed during Winter.

Double glazing offers more than just increased energy efficiency however. Your home can also benefit from maximum wind resistance and optimum water tightness, even in seaside areas where the windows stand strong in their performance even when challenged by strong winds and the salt air.

You can also add to these benefits an increased level of security and excellent sound insulation, which is particularly important if the property is located near a highway or in a built up area. Noise levels can be significantly reduced as the double glazing minimises the level of double passing through.

The Leading Provider of Double-Glazed Windows in Australia and How They Work

Here at Ultimate Windows, we’re seasoned specialists who understand the intricacies of what we’re selling. If you’ve never heard the term “double glazing” before, you might not know how simultaneously simple and invaluable it can be. What does that actually mean? Double glazing windows really just mean adding an additional glass pane layer parallel to the first. Similar to an aeroplane window (but a lot more stylish), it’s two panes of glass with a tiny space between them for air to flow. That’s most of the mechanics right there. 
So, how does it work? Well, while glass conducts heat quite well, air does so very poorly by comparison. So, by leaving a layer of air between the glass panes, you’re preventing most heat from going all the way through the window. Your double glazed windows are therefore excellent at keeping hot air on whatever side of the window it’s already on. If you’re heating your home’s interior during the winter, you’ll lose less heat. If you’re desperately trying to fight off the Australian summer heat, these windows will keep most of that heat outside where it belongs!

The Magic of uPVC Framing in Our Double-Glazed Windows

Here at Ultimate Windows, we’re confident in the quality of both our work and our products. So, we’ll let you in on a little secret: Our state-of-the-art uPVC window frames aren’t some magically advanced tech that’s only just come out. In fact, uPVC is extremely popular all across Europe. It’s manufactured across Europe and has become the standard across plenty of Western Europe for its reliability, durability, and versatility. In other words, uPVC just makes sense as a standard. It’s everything you need in your windows and glass doors. 
So, why isn’t it the standard here? Well, we take our time with the sensible stuff here in Australia. That’s why we at Ultimate Windows are working to make uPVC the standard here as well. uPVC works in tandem with our window double glazing to offer maximum control over heat flow and air leakage. Two or even three panes of glass already serve to prevent heat transfer and block out noise and plug air leaks. Solid uPVC framing serves to extend that coverage to the frames, creating a reliable seal for maximum noise cancellation and air control.
