Four Great Advantages and Benefits of Double Glazed Windows
October 30, 2014 by Viola Sacci
It doesn’t matter where you live or what you do, the benefits of Double Glazed Windows are going to make your house a nicer space to be in.
Here are the top 4 reasons why you need double glazed windows in your house.
1. A Double Glazed Thermal Dream
With heating and fuel costs going through the roof these days, getting double glazed windows really is a no-brainer! They’re thermally efficient and keep as much of your heat inside where it belongs. Your old windows may have been leaching out your heat (and your money!).
Not only do these wonderful inventions save you money in the winter, but they also help you save tonnes of money in the hot summer months. Your cooling costs can also be dramatically reduced by the implementation of double glazed windows. The glass acts as a barrier to the sweltering heat from outside that’s attempting to penetrate your icy fortress.
In a nutshell, it will keep you warmer in the winter and cooler in the summer!
2. Double Glazed Windows; are (Noise) Killing Machines
One of the best features about double glazed windows (especially when acoustic glass is used) is that they’re practically sound proof. Do you live by a busy highway? Enjoy your AFL matches in surround-sound bliss with your double glazed windows.
Perhaps you live in a school district. Are noisy kids cantering past your house every day giving you the blues? Block out their high-pitched chatter with a brand new set of double glazed windows!
Do you live near a construction site? An airport? Or maybe you just have annoying neighbours. The fact is, with double glazed windows you can seriously reduce the noise pollution affecting your home. Hooray for silence!
3. Less Water Damage
Have you ever poured cold water into a glass and then watch the glass get super misty? Of course you have. That’s called condensation. Welcome to 5th grade geography class! Condensation happens when warm air is cooled. Our old single-paned friends have serious issues with condensation. You see, when it comes to windows, condensation is bad.
Think of your home as a giant glass of water. When your air conditioned windows come in contact with the heat from outside, it will form water droplets on your windows. The same thing happens when inside is warm and outside is really cold. Now the water droplets are harmless on their own, the real damage comes when they trickle down to your window frames or seep into your walls.
Over time, this could cause extensive water damage and cost you quite a bit of money in the long run. Double glazed windows aren’t immune to condensation, but if they’re installed properly and made with the right material, the chances of this happening are very slim. The inner pane of the window acts as a barrier between the sharp differences in temperature.
4. Double Glazed Windows are Greener Living
If you’re environmentally conscious (you should be!), then you will definitely appreciate this benefit of double glazed windows. More and more glass manufacturers are opting to use recycled glass for its environmental benefits. Apart from that, double glazed windows are very energy efficient and help to reduce your fuel consumption by controlling heating and cooling losses through proper insulation.
Double glazed windows are pretty amazing. They will save you lots of cash in the long run, they’ll protect you from annoying neighbours and they will reduce your environmental impact. They are an all-around good investment for any home-owner, whether you’re planning to sell or you’re in it for the long-haul.
Double Glazing in Europe vs. Australia
Over the last week, I Connected on Linkedin with Dimitri Geleen, who’s a creative IT professional with broad experience in Project Delivery, IT Ops and Business Analysis. Dimitri works in Berlin. So what’s the connection with double glazing, you ask?
Well, in the course of our discussion, Dimitri mentioned that he has double glazing. Now that’s hardly surprising. In most of Europe, double glazed windows and doors are the standard. In many cases, it’s triple glazing. Of course, in Australia, we’re very late to the double glazing game, and still trying to convince the local building industry to recognise that double glazing should be our standard, too. If we really cared about housing affordability, we’d give weight to the value of cutting our ridiculously high heating and cooling bills.
Anyway…. I asked Dimitri to tell me a little about his use of double glazing. So he did. Tell me a little. But, the little he told me was very powerful.
He sent me the photo you see above, with the words
“I made a picture of my little private office in Berlin with almost over 100 year old double glazing. Thought you might enjoy that.”
Enjoy that? I LOVE it. Shows that local practice is 100 years behind Germany.
So, are you a little shocked that we’re 100 years behind Germany? Well, buckle up your seat belt, because we’re some 2000 years behind the Romans!
Double Glazing In Ancient Rome
Yes, the ancient Romans used glass in windows, but not the clear glass we use today. Nevertheless, they went one step further.
According to Wikipedia, they found out that insulated glazing (or “double glazing”) greatly improved their ability to keep buildings warm, and this technique was used in the construction of public baths. Over 2000 years later, the vast majority of Australian homes still don’t have double glazing
No slouches in the field of energy efficiency, the Romans also developed underfloor heating, which today usually takes the form of hydronic heating, circulating hot water through a concrete slab floor. Australia, catch up!
Good Window Design & The Importance of Double Glazing
Is Double Glazing Worth The Money?
IS double glazing worth the money you invest? The answer is YES, but ONLY if it is installed correctly, without a cold bridge (thermal bridge). A window or a door is essentially a hole in the wall and responsible for most of the unwanted heat loss or gain.
Windows are essential for a house and the comfort and well-being of its inhabitants, as they let natural light and fresh air into the building and enable views. Appropriate window design, size, location and glazing treatment, combined with shading and internal covers, can significantly reduce the energy required for heating and cooling. Maximum solar access for north-facing windows can reduce winter heating bills up to 25%. External shading can block up to 80% of summer heat gain through windows. Double glazing and internal coverings can reduce heat loss in winter up to 40%.
Glass is the potential weak point of a building in terms of energy efficiency. A single glazed window can gain or lose up to ten times more heat than an insulated wall.
uPVC Double Glazed Windows in Australia: Video
Available across Europe and America for the past 60 years, uPVC window profiles are the most popular choice to deliver superior and proven performance worldwide.
More than half of all new and replacement residential windows worldwide are uPVC. That’s almost 290 million window units a year.
Chosen for their durability, low-maintenance, high energy efficiency, performance and style, the US and Europe have long focused on energy-efficient windows.
However, in Australia, we’ve traditionally used either timber frames which are good insulators but high maintenance, or aluminium window frames which need less maintenance than timber, but have poor insulation .
Thermal performance is one of the most important characteristics of a window. Double glazed uPVC windows can be as much as four and-a-half times more energy efficient than standard single glazed aluminium. The energy efficiency of a window system is commonly defined by two measures.
First, the solar heat gain coefficient (SHGC), a measure of the solar radiation going through the glazing into a building, and secondly by the rate of heat flow through a window system (uValue). For both measures, the lower the number, the higher the performance.
A common misconception in Australia is that double glazing is only for cold climates, to keep the cold outside. But double glazing is also just as effective in keeping the heat of an Australian summer OUT. In fact, standard glazed windows contribute to eighty-seven percent of the summer heat gain in a typical Australian insulated home. Choosing double glazed units with low solar heat gain and lower uValues reduces or eliminates the need for expensive artificial cooling. By replacing your windows with high-efficiency upvc ones, you can reduce greenhouse gas emissions from household heating and cooling by more than one ton a year.
uPVC windows are considered durable, with expected life spans of 35 years, and leading brands have been tested specifically for resistance to australia’s high UV radiation levels. These windows will look good for years without the need for sanding or repainting, and being resistant to salt, are ideal for coastal locations.
uPVC window profiles have been carefully engineered to incorporate multi-point locking systems, providing a high level of security. They can be used in a wide range of styles for old and new heritage or contemporary homes, and they come in a variety of colors. Choose with confidence from a range of quality suppliers in Australia.
Double Glazing Stars in Canberra Home
Presented by the ATA (Alternative Technology Association), the 2017 Sustainable House Day opened over 200 homes to the public, and attracted over 24,000 visitors nationwide. On show were homes that showed how sustainablility, liveability and economy can work hand-in-hand.
The Blue House has been called ‘a home with heart’. It features an effective passive solar design, salvaged and recycled materials, an innovative whole-block water harvesting system, and, of course, double glazing. This little owner-built home provides a comfortable base for the young Canberra family of Shelley and Luke Dickerson.
The two-storey house contains three bedrooms and a studio, plus a split-level kitchen, dining and living area. In keeping with passive design principles,, it’s aligned so that all main rooms have a north window, and a big deck provides a good connection to the garden. Double glazing, good cross ventilation, a concrete slab for thermal mass, a heat pump hot water system and 3 kW of solar PV all assist with the all-electric house’s thermal performance and energy efficiency.
