uPVC Double Glazing Made in Melbourne with the Unsung Hero of Modern Materials

Sometimes a simple word prevents something from receiving the respect it deserves. uPVC is a good example. We are all familiar with PVC and many people will know it stands for polyvinyl chloride. It is lumped in with all the other plastics, with their flimsy, throwaway characteristics. But that does uPVC a terrible injustice. The u at the start stands for unplasticised, and what this means is that uPVC is more rigid, tougher and worthy of a place among the more respected materials, such as metal and timber. If you talk of double glazing in Melbourne, many homeowners and builders are only yet to discover the benefits of uPVC double glazing and still relying on inferior products such as aluminium. While other countries have long discovered the benefits of uPVC double glazed windows, it has gained more popularity across Australia within recent years. But what does that really mean? Let’s analyse this thing that has transformed domestic comfort all over the world.

How does uPVC Double Glazing Work in the Melbourne Weather?

Heat and cold have a way of penetrating materials, and double glazing was invented to put a slight gap between two panes of glass, interrupting the heat or cold penetration. So, that’s the glass doing its thermal job. But what about the frame, the part that surrounds the glass? Looking for a superior material to wood, which has a tendency to rot over the years, double glazing installers began to use aluminium, which retains its integrity while good old wood gets old and weak. The trouble with aluminium is that it is a good conductor of heat and cold, so the temperature outside creeps through the frame itself and into the building. When you’ve installed double glazing to avoid that, using aluminium is like shooting yourself in the foot. uPVC double glazed windows have proven to solve this issue effectively. Tough, durable, and resistant to temperature transfer. And good looking! Tested and trusted worldwide for decades, double glazed uPVC, is a material particularly well-suited for Melbourne’s variable climate. uPVC double glazed doors and uPVC windows in Melbourne are here to stay – in more ways than one.

uPVC Double Glazing Doesn’t Have to be Plain White

uPVC double glazing is everywhere now. We take it for granted. But did you know it can be made in various colours? We do cream, various shades of timber look windows such as brown, grey or black. Because some people like the look of aluminium look windows, we offer that look too, but with the unique properties of uPVC, the king of double glazing materials. So the next time you’re out and about, pay attention to the windows you pass. Some of the most attractive buildings in the city are examples of double glazing in Melbourne. And the great thing is that they’re still going to look great and work well in all respects many years from now.

Getting Double Glazing Installed in Melbourne Puts You One Step Ahead

You know the old saying, “There is no such thing as bad weather, just the wrong clothes”? You could apply that to buildings. Part of the appeal of Melbourne for many people is the fact that it is a “real” place with a proper climate. And that means it is not relentlessly hot and sunny. The temperature varies and sometimes we have a drop of rain, which is good for the plants, the gardens and the environment in general. It’s only a problem if you’re not prepared for it, and as regards your home, that means having windows that can regulate the changes through double glazing. uPVC windows in Melbourne, Victoria give you control. They keep the heat out when it’s a bit much and the cold out when that’s threatening to put a dampener on your day. They even do a job on the exterior noise factor, reducing it by up to 60% as opposed to conventional single-glazed windows. But it’s the temperature regulation that makes our double-glazed windows in Melbourne so popular. Double glazing technology uses that little gap between the panes to stop temperature changes in their tracks. And with side-hinged (casement) or top-hinged options, plus double glazed sliding windows and tilt-and-turn versions, you are in control of the conditions in your home.
