What are Double Glazing Windows?

Double glazing and double glazing windows are terms that are thrown about a lot in the home improvement industry. This is in the assumption that as an established product, everyone knows what it is – but that isn’t always the case. Available with any home renovation that includes prominent glass panels, double glazing is, in short, two panes of insulated glass within the single frame.

All the elements of installation must be considered when you look at the features and advantages, and how these weigh up alongside double glazing prices.

This, in turn, offers a much higher level of security and energy efficiency than older, outdated single pane glass panels. As a result, double glazing, especially in windows but in all products, is incredibly popular. Improved energy efficiency means that in time you could save money on energy bills, as less heat will escape through the insulated glass.

Double Glazing Windows & Styles

In today’s market, double glazing windows aren’t just exclusive to modern frames. Double glazing is generally available will every type of window frame. Whether you’re looking for something more complex, or even a more traditional frame, there’s something for you.

Here’s just a snippet of the double glazing window options you could invest in with one of our approved installers:

Casement windows

Casement windows are seen in the industry as the most popular and standard choice of double glazing window on the market. As with every frame, they deliver excellent thermal efficiency and are a robust, secure choice of home improvement.

In several instances, they offer the most configuration and customisation options, which in turn makes them a highly versatile option among double glazing window styles. They are often available in a vast range of styles, which in turn means they can suit just about any property.

Flush Casement Windows

Similar to the ever popular casement style, flush casement double glazing windows offer a touch of class wherever they are fitted. If that’s what you’re looking for with your home renovations, they could be the choice for you. They are one of the most visually appealing window frames when shopping for home refurbishments.

Flush casement frames are seen as a modernisation of older wooden windows, offering a similar style but instead made from sturdy uPVC. However, unlike the older frames, the double glazing windows will provide better heat retention, soundproofing and weatherproofing.

Sliding Sash Windows

Investing in new double glazing windows doesn’t mean you have to totally modernise your home. In fact, there are options that will allow you to maintain the appeal of an older property and sliding sash windows are one of them.

Often built to replicate the older frames perfectly, several installers will offer sliding sash windows in a range of timber finishes, to better mimic the traditional appeal. However, with the inclusion of modern double glazing, they’ll offer brilliant heat retention among other perks.

French Windows

Double glazed French windows are exactly what they sound like – a windowed version of your typical French door. These are a stunning option for garden facing kitchens, as the removal of any central reinforcement allows plenty of natural light to enter the home.

However, with the inclusion of double glazing, you won’t have any concerns over the level of security you’re getting with the window itself. It will do well to protect against the worst. Double glazed windows are also incredibly weatherproof, meaning the rain and wind will stay outside as well.

Tilt & Turn Windows

Tilt & turn windows are an impressively functional style of double glazing window, as they can double up as an emergency exit in a worst case scenario. This can offer you peace of mind, especially if your home has hard to access areas that could easily be cut off.

As a result, tilt & turn windows come with complex integrated hardware, but that doesn’t mean they’re partial to breaking. In fact, many installers will offer guarantees for the quality of their double glazed windows. Tilt & turn frames also often require limited maintenance after installation too.

Bow & Bay Windows

Another style of window that is re-worked off of a more traditional look, bow & bay windows have a range of modern benefits for homeowners. First and foremost, they offer the illusion of more space, by making the room seem much more open. They are an excellent option for bedrooms and lounges.

You’ll often see these windows in period homes but those dated frames will have cold spots, and if they’re made from old wood, they may have also rotted too. With many of the installers on our site, you’ll get a uPVC bow & bay window which comes with as much as a ten year guarantee for its quality.

Double Glazed Window Materials

When looking to invest in new double glazed windows, you have more choice than just the style of the frame. You’ll also be left with the choice of material with many styles as well.

uPVC Double Glazing Windows

With double glazing windows, uPVC remains the country’s most popular choice of frame material, thanks to a range of benefits and unrivalled versatility. uPVC, or Unplasticized polyvinyl chloride if you’re interested, is an incredibly robust material and therefore it’s used across a range of home improvements.

You’ll also find double glazed doors and conservatories which are made from uPVC, proving its rigidity whether it’s used in small or large quantities. It’s especially useful with the manufacturing of windows. This is because it can be made to fit the range of styles mentioned above, and to fit any space you may have available.

uPVC is a cheap material to manufacture too, meaning they’re a fantastic option if you’re shopping for double glazing on a budget. Despite this, they will not wither away easily and will provide great longevity. Contrary to what many believe, uPVC also isn’t a toxic material unless heated way beyond what it would naturally experience. All in all, it’s a fantastic choice of material for double glazing windows.

Aluminium Double Glazing Windows

However, uPVC is not your only option when in the market for some new double glazing windows. In fact, it has some serious competition.

Aluminium products are all the rage right now, thanks to being both lightweight, and incredibly sturdy. Both qualities make for a great material when building double glazing windows. Their longevity as a product can – in some instances – exceed their uPVC counterparts. Several suppliers will rubber stamp their aluminium products with as much as a 20 year guarantee.

As the material becomes more and more popular among installer and customer alike, the range of aluminium styles you can get with double glazing windows has grown also. With most of the window options mentioned above, you can instead get them made from aluminium.

With this option you’ll get slimmer frames which allows more natural light to enter the home, making the most of the stunning double glazing. Aluminium frames also require very little maintenance after installation. Although they’re a pricier option in comparison to uPVC, many consider them the superior product.

Replacement Double Glazing Windows & Options

If you’re interested in replacing the glass in your windows but not changing the frame itself, you still have plenty of options. Many of the approved installers on our site will offer replacement glass services if your current glazing is outdated and subpar.

Naturally, if the frame itself is wasting away, then your installer may recommend an entirely new window. But if it’s in good condition then replacing the glass may be the smarter option. It can come out cheaper, and with the perks of double glazing windows, they could actually save you money in the long run.

Double Glazing Windows, Costs & Prices 2018

Naturally, it’s tough to give an exact price for double glazing windows because of the range of variables – size, style and material all play a part in increasing and decreasing the rough estimate.

For example, a uPVC casement with one opener would cost between £250 and £450 dependent on size. However, it’s good to remember that local and national installers way offer differencing price ranges. Meanwhile, a sash window with double glazing in the same size range would instead be around £525-950.

A range of our installers will offer some of their more traditional frames in woodgrain finishes, to again better replicate the look of the classic models. These, among other colour options, come at a premium. A woodgrain finish would cost around £100 more each per window.

Finally, however, it’s important to know that many installers will offer deals when multiple windows are built and installed within the same renovation. This means that if you’re investing in five or six windows, your quote may come out less than expected.
