Expert tips about double glazed windows installation
Past Chris Stead, Finder's skillful DIY and abode renovations writer
Are double glazed windows worth the investment?
Absolutely. 1 of the key benefits of double-glazed windows is sound insulation. Double glazing does an effective chore of blocking out audio, depending on what window openings you lot go for and how well they seal. You can still hear what's going on outside, but it's not enough to wake you lot.
If yous're not in a noisy area, you may be wondering why that would be a selling bespeak. Simply there are two boosted reasons to consider; firstly, will it ever be tranquility where y'all live? What if the neighbours renovate? Or the council decides to rezone nearby land or build some infrastructure? What about the noise in your firm? Similar your booming dwelling house theatre? Maybe you want to proceed the noise inside from getting out as much as the other fashion.
The second reason is because of the second bigger do good; temperature insulation.
There are very few places in Australia that don't suffer from extremes in temperature, be it predominantly cold or hot. I'll bear on the types of double glazing in a second, but the theory of having two panels of glass separated by a gas (usually argon) chamber is to prevent the transfer of something outside from getting inside, or vice versa.
With double glazing, hot or cold hair needs to hit the outset console, transfer through, brand it across the gas, and then transfer again. All while the reverse temperature is trying to do the same thing. For example, the hot summer air is trying to get in while your air-conditioned house air is trying to get out.
I've found double-glazing to work incredibly well. Every window and glass door in our home is double-glazed and the temperature in the firm does a nifty job of self-regulating. There is plenty more that goes into that – I have practiced insulation crammed in every wall and in the roof, plus blinds to cake out direct sunlight – but it requires a sustained 24-hour interval of farthermost temperatures earlier I demand to resort to the air-conditioner downstairs.
Upstairs, where the dominicus directly hits the roof and to which hot air rises, I do need to cool the rooms before sleep on hot nights, but so the double-glazed windows exercise a skilful job of keeping that cool air inside the home. So, I usually but run the air-con for 30 minutes before bed and and then maybe once more in the middle of the nighttime for 30 minutes on belting hot or frigid evenings.
Can yous install double glazing yourself or is it ameliorate to phone call in a professional?
Most window companies volition install their windows for you either directly or through a preferred trade at an additional cost. I didn't become this route; merely I wish I had. We had the windows delivered and so installed them ourselves with the help of the carpenters that were working on the framing and external cladding. While nosotros did get the job done, information technology toll me more in their labour than it would have to get the professionals to do it simply because each manufacturer has their own quirks.
And then the chore wasn't as adept because the local chippies weren't familiar with the production.
Plus, these windows are bloody heavy. Our biggest windows were approximately 2 x i.4m and it required four guys to lift it upwardly onto the sill. And then it must be fixed into place while you're holding it. Not only is that a lot of labour toll, but there's a lot that tin go incorrect when you are moving objects with that much weight. Scratches, dents and worse are possible, which is why it's good if information technology's all on the head of the professional person installer.
Of course, these issues may non exist a concern if you're only putting in ane or two small windows, just information technology's as well important to remember that windows and doors – especially sliding doors held in a track both pinnacle and bottom – volition rarely just fit perfectly into place. In that location's a off-white fleck of piece of work to do getting them level, packing them into the crenel and securing them. As such, yous'll likely need some in-the-moment carpentry done, which you'll either need a chippy on hand for or have the ability to exercise yourself.
What type of window glazing would yous recommend?
In full general, your options are:
- Double glazing separated by a vacuum
- Double glazing separated by a gas
- Low-east double glazing separated past a vacuum
- Low-east double glazing separated past a gas
Equally yous descend that list, the insulation improves, but so does the cost. Then each again is impacted past the thickness of the glass panels and the gap between them. The vast bulk of Australians will be used to days or even weeks of very hot weather. Some of us experience cold weather, too. But most of us don't alive in freezing conditions (such every bit Scandinavians) or relentless rut (like Indonesia) all the time.
My point is that y'all don't have to go over the top. You can probable get abroad with drinking glass 4 to 6mm thick, and and then a gap between the panels around 6 to 10mm, depending on where you live and how much direct sun the window gets.
Every bit for low-e, this refers to emissivity. Finer this option has a movie coated onto the drinking glass to help further reduce the transfer of energy. There are other options in this regard, too. Tinted and reflective drinking glass, or color toned, for case. At that place'due south fifty-fifty laminated drinking glass which doesn't shatter and does a good job with audio.
What did I do? I went for a six-8-6 double glazed window separated by gas. (Every bit in 2 6mm panels separated past 8mm of Argon gas).
What type of double-glazing window frame would you recommend?
In that location are 3 primary frames to think about; aluminium, timber and uPVC. Allow me steer you lot away from timber directly abroad. Information technology looks great and has solid insulation capacity, only the budget – painting or staining - is never-catastrophe. They're harder to clean. Plus, they're harder to seal as they expand and contract in the estrus, significant they do a poor chore on audio.
Aluminium is cheaper, gives yous a wide choice of colours, a decent sound seal and it'due south easy to make clean. They can find a scratch that's for certain, but their principal downside is that the metal is a temperature usher. This can hateful all the hard work your drinking glass is doing can be undermined by its frame. Aluminium frames are also relatively heavy.
The tertiary option, which has become more affordable since I built my business firm, is uPVC (Unplasticised Polyvinyl Chloride). Yes, information technology'southward a plastic, simply fabricated rigid and sturdy like metallic. Information technology'due south got plenty going for it. It's lightweight, fire tolerant, doesn't colour fade (although at that place are less colour options to brainstorm with) and is potent enough that it doesn't need to exist as thick every bit aluminium or timber, which means more glass to look out of.
What I similar most about uPVC as an option, even so, is that information technology seals ameliorate than the other materials, providing better sound and heat insulation. Well, if you can afford it.
In recent years, nosotros've as well started to come across fibreglass window frames enter the Australian market. It'due south an awesome product or framing due to its strength, its ability to tolerate temperature extremes without moving and its incredible insulation. It has been known to leak, however, and it is all the same very expensive.
I went for aluminium on my home, although I had information technology thermally broken. This improver puts a prophylactic buffer in the frame, effectively splitting information technology into two halves; the condom slows downwards the transfer of temperature through the frame. Equally I was ownership so much glass to fit out a 2-storey abode, I decided to put my coin into the double-glazing itself, and pare back on the framing. I'm happy with the results, though I would have loved to take got the tighter seal of uPVC had my budget stretched that far.
How should double glazed windows open for best results?
Taking a broad view, you lot'll exist looking at three types of window opening systems. The archetype slider, the casement/tilt and the hung. Casements offering a much better seal, which is adept for temperature simply mostly ideal for audio. Sliders and hung windows are easier to flyscreen, but seal poorly in comparison.
Nosotros went with sliders in about rooms and information technology was a mistake as sound was a big business organization for us given we alive opposite a park. I should take gone with casement windows and spent more than on a bespoke, imaginative wing screen solution (for example one that isn't fixed but can be slid to the side for window access).
If audio isn't an issue for yous, however, then the world is your oyster.
Is retrofitting double glazing to your existing window worth it?
If you're not edifice a new structure, but are instead looking to improve your existing residence, then retrofitting is worth because. This allows you lot to continue the existing frame and cavity, and either add in a new double-glazed glass in full, or to just add together a second glass panel to create a double-glazed effect from your existing single pane window.
The reason why you'd want to retrofit rather than put in a whole new window is because the removal of your existing window would be very invasive and expensive. This is because the window frame is unremarkably embedded in both the internal and external structures. To remove it you lot'd need to destroy all the architraves, any windowsill, potentially some gyprock and then, outside, some cladding, bricks or render. It's almost impossible to remove these elements cleanly as they were likely glued into identify and/or full of screws and nails that take failed over the years and won't come out. Or, in an old dwelling, information technology could be asbestos!
And then once you put the new window back in, all those elements you just destroyed demand to exist re-built, painted and finished. It's a huge cost.
Then, unless y'all simply can't live with the existing frame, retrofitting is a much smarter choice. Plus, it gives you the flexibility of focusing first on windows that become direct sun or sound; you don't have to get every window done at once if budgets don't allow.
