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 and doors 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 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. 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. Double glazing uPVC windows 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.

I cannot recommend Thermal Double Glazing enough. I previously had 2 large front windows installed by another company and I was very nervous looking for another installer for my back windows. I have a small unit but the whole process with TDG has restored my faith. The 4 windows and one sliding door are absolutely amazing. The meticulous finish on the windows has resulted in a premium look. From the first contact with Michael, the on-site measurement with Tom and the installation with Tom and James, nothing was a problem. My concerns were respectfully addressed at every stage. The windows look amazing, particularly from the inside and I already open my windows more.
If you want great double glazed windows from a reputable team it has to be Thermal Glazed Windows.
PS. Even the display at the home centre in Frankston was worth a visit. Photo is just one window before and after.

We needed to replace our aluminium framed 3mm single glass pane windows and our aluminium framed sliding glass door in our 1960s house. We had 8 companies quote for the job. It was only Thermal Double Glazing who said they could install our new uPVC double glazed Tilt and Turn windows without removing our beautiful hardwood window frames/sills & replacing these with MDF/ pine ones. Keeping and working with our existing hardwood window frames/sills kept their quote very competitive as it involved less labour and materials. From our first contact to the final installation, Thermal Double Glazing were amazing! Michael was happy to talk about what we wanted and how it was very possible. His long experience with window installations was very reassuring. When Steve came to measure up, we were even more reassured when he showed us, in a very confident manner, how it would all happen. When installation day came along after a much shorter waiting period than the other quotes, it all went well and to plan!! Steve’s team showed their skills as window installers with extensive experience here and in Europe where these uPVC windows are extensively used. Our new uPVC double glazed Tilt and Turn windows and new uPVC very effectively sealing sliding glass door have made a HUGE difference to keeping our house warm and reducing the noise from outside. A big THANK YOU to Michael, Erin, Steve, Suki and Jason for their excellent work and the manner in which they carried it out. We would without any hesitation recommend Thermal Double Glazing to anyone!

Fantastic team and product. From my initial contact, to discussing my particular requirements, to last minute change requests it was a pleasure to work with the team at Thermal. My windows were delivered on the predicted date and time, the installation team went out of their way to ensure everything was installed to a high standard, everything was left clean and tidy after work completed. The product is great (should have done this years ago). No more draughts, stable indoor temperatures, reduced heating costs, looks great. Even my cat approves.

We are delighted with the whole job from the measure and quote through to the installation.
Michael knows what he is doing; straight down the line, with no pressure tactics or tricks- and no variations, which I was nervous about.
The installation crew, Steve, Robert and “Silk” were terrific; really decent blokes, friendly and sensitive to minimizing any disruption caused to us in the process. They were ultra neat and tidy, vacuuming at the end of each day’s work and expert at what they do, have delivered a result that looks and feels great.
Couldn’t recommend highly enough.

We needed to replace our original 1960s steel framed windows with 3mm glass. We had eleven companies quote for the job, but it was only Thermal Double Glazing who were able to promise they could replace our windows without damaging or needing to replace our beautiful hardwood frames/sills or need to replace our blinds. It was very important to us to maintain the character of our home and Michael (the director) with a building background was the first to promise that his team could and would do this and also acknowledge our wishes without making us feel as though we were asking for the impossible. It was also refreshing not to experience the hard sell or pathetic sales tactics that many of the other companies employed. During the quoting process all questions were answered by Michael with honesty and respect. We expressed our desire to have our windows installed before Christmas if at all possible. Michael did everything he could and made it happen.

While Thermal Double Glazing were not the cheapest quote we received, the product (German designed, Australian Manufactured uPCV), the installation and the aftercare has been exceptional as promised. The installed windows have resulted in a massive noise reduction, minimal loss of heat and a constant and comfortable house temperature. While we are yet to have our first winter with the windows, we are hopeful they will fix the condensation issues we were experiencing with our paper thin windows. The installation process was seamless and carried out very professionally by Steve, Shawn and Izzy. The team were respectful at all times and ensured that our young family were part of the process and explained what they were doing to help the kids make sense of what was happening to their house. Steve was more than happy to address minor issues after installation (he identified a minor hole in one of the fly screens) and fixed them quickly and without hesitation.

We are so happy with our windows, and are thankful for the Thermal Double Glazing team for making the process smooth, for completing their work to a very high standard, and for being respectful and pleasant in all interactions (massive shout out to Steve!). Big thanks to the whole team! Highly recommend Thermal Double Glazing.

I cannot speak highly enough about the product and professionalism of installation.
Both Michael and Steve have been a pleasure to deal and communicate with.
The windows themselves are absolutely amazing and beyond our expectations, so much so, that we will be fitting out our whole house in the future.
Once again, thank you so much Michael and Steve, who did a great job installing them, but also took pride and great care to not cause any damage and also tidied up and vacuumed the rooms he had done the work in.

Thank you Michael and your team for installing the new windows. In Autumn this year I had Thermal Double Glazing replace original single glazed aluminum framed windows with double glazed uPVC windows. I held off my review until winter was over, I wanted to see how they performed. Reducing the cold inside the house was the main reason for replacing the windows. I can very happily say, I am extremely happy with the outcome. In the house, overnight it wasn’t as cold as pervious years, and no more condensation on the inside of the windows in the morning. The added bonus, I no longer hear the neighbours pool filter running or the other neighbours split system air conditioner, it dramatically reduced the noise. The whole process was smooth from start to finish. Michael came to measure for 10 windows and 1 sliding door. He listened to what I wanted to achieve and came up with great suggestions, a smart slide door – it glides so smoothly and effortlessly, best advice. And big picture window with a side tilt turn window, to take full advantage of the garden view and it makes the room look bigger. Steve and Shaun are such great workers, left the place neat and tidy at the end of the day and respectful of someone else’s home. It was a pleasure to have them working in the house. And for me, who is into sustainability, it was an added bonus to know this company is also, and is a partner with the Plant-A-Tree-Program. I can highly recommend Thermal Double Glazing, Michael and his team. Tanya R Chirnside Park Vic
