Did you just purchase a double glazed window and confused about how to have it installed? Fitting the window yourself can be quite easy with the help of this step by step guide. However, if you lack proper training or experience, we’d recommend you reach out to a trustworthy professional who can guarantee the best results for help. That said, now let’s take a look at the process.
• Remove the old windows by detaching the old beading and glass window safely. Then make some interval cuts using a hand saw before using a crowbar to pry it out.
• Cut the external double glazed window seal. Once done, take a measurement of the window area’s width once empty. Then transfer the measurement to the window sil to face outside and cut using a handsaw.
• Seal the window sil. Add a bead of clear silicone along both inside lip as well as the centre to seal the sil.
• Screw the double glazed window to the sil. Position the window on the top of the lipped section that was siliconed. Then pre-drill them together and screw in three places. You should make sure the screws do not go totally to the sil’s bottom.
• Install the double glazed window. After successfully screwing the double glazed window to the sil, you can now fit in the double glazing. Make use of packers to make sure it’s even in the slot.
• Screw the uPVC window to the wall. If you’re happy and satisfied with the position of the window, you can then pre-drill through the frame of the window and the brick wall. Once done, simply screw it in place using masonry screws or Spax screw as they do not require crawl plugs in bricks.
• Seal around the window. To do this, simply fill any gaps with expanding foam, wipe out the excess and seal with silicone.

To counter this problem and still benefit from a warmer home and cheaper bills, secondary glazing is an option. Secondary glazing is a second pane fitted inside your original window. Secondary glazing will still save you around £105 yearly.
Are you about to purchase a double glazed unit and wondering how to go about the replacement project? If yes, then you’re at the right place. Firstly, it’s advisable to hire the services of a reliable professional who can guarantee the best results for help especially if you lack proper training and experience in the field. However, we’ve put together this step by step guide to provide you with a detailed information about the double glazed unit replacement process. Let’s get started!
The tools and materials you require for the project includes tape measure, hammers, nail punch, scraper, spacing blocks, non-hardening butyl putty, high-security glazing tape rolls and beading tacks.
• Work out the glass size required. Simply use the tape measure to measure from frame edge to frame edge while also taking note of the thickness.
• When about to order, inform the glass merchant that the measurement provided are frame-tight. This will make him reduce the dimension a little bit, mostly by 5mm for clearance.
• Remove the beading and ensure to support the glass while doing so. If the glass units are fitted in wooden windows, you may need to cut the putty-based compound they’re normally sealed with to remove the glass.
• Lay out the beading in the window’s shape to make for easier refitting later on.
• If you’re working on wooden frames, wipe out all traces of excess installation compound using a scraper and clean the rebate with a soft brush.
• Trial fit the double glazed windows to ensure they’d slide into the frame without being forced.
• Plastic frame windows are usually in between a pair of gaskets, you should replace this with a hight security glazing tape. While for a wooden frame, simply apply strips of flexible non-setting butyl putty or high-security glazing tape on either sides of the glass.
• Install and centralize the glass in the frame.
• Press the nail wooden beading or plastic beading back into place.
The simple answer to this question is... they can be! Although there are many types of porch designs that are available in the market, the uPVC porch happens to be one of the most loved and cost effective. Most home and property owners prefer the installation of a uPVC porch for a number of reasons. These includes:
• Value for money
It’s no coincidence the uPVC is widely accepted across the building industry with a plethora of uses. Not only is it relatively inexpensive to manufacture, but even the recycled uPVC is now becoming more and more useful. UPVC’s main rivals are wood and aluminium, and both are way more expensive to incorporate for frame profiles. Therefore, making use of uPVC is going to make your initial costs relatively low.
• Life Span
Although the main rivals in both hardwood and aluminium can also boast a lengthy lifespan just as uPVC. However, considering the price that you can get a uPVC, the lifespan is just incredible as it can be measured in decades.
• Aesthetic Appeal
UPVC gives you a wide range of foil colours that’ll fit your home perfectly well while also enhancing it’s visual appeal. You can actually get a porch that looks exactly like it’s manufactured from timber frames. To achieve this, all you need to do would be to make use of a wood grain surface finish. This is also long lasting, strong and resistant to fade.
• Little Maintenance
This is a very common feature of uPVC that makes it even more advantageous when used in making a porch. Unlike timber or wood which swells due to absorption of water or shrinks, you’ll never need to worry about all these distortions and more with uPVC. No painting, no sanding and ultimately, low maintenance required.
If you’ve got a problem with condensation and don’t have double glazing, you should find that getting new windows will help. Condensation is caused by warm air meeting a cold surface which then turns into water droplets. With two panes of glass, less heat will escape from your home and keep the window warmer, meaning when steam from the bathroom or kitchen touches your windows there should be less condensation.
One of the essential factors that makes a home truly a home is the convenience and comfort it provides us. As a result, we usually have a long to do list comprising things that come together to make sure our home is comfortable with ambient temperature at the very top of the scale of preference. After all, no matter how greatly designed your furniture and home decor is, it probably would amount for nothing if the temperature is either too hot or too cold. Some of the most common ways we incorporate to make the temperature a lot more conducive and warm during the winter months is by installing air conditioning system or through top notch insulation materials, but the fact still remains that a lot of heat would escape through the doors and windows. And that’s exactly the use of double glazing. So how exactly does double glazing work?
Double glazing basically works by preventing the escape of air and trapping it between two panes of glass. It’s the trapped air which serves as an insulation barrier which delivers 3 major functions. First and foremost, it stops the escape of heat through the window as the barrier created insulates the room from varying air temperatures at both sides of the glazing unit. The second major function is the double glazing works to keep down noise pollution coming from outside. While the third major function of double glazing I the fact that it helps minimize condensation which usually occurs on the single glazed windows’ inside as the cold outside air works to cool the warm air inside the house. When you install a double glazing window, the insulation barrier generated will work to stop the air temperature transmission which ultimately helps prevent the occurrence of condensation.
It depends on a few factors whether a new double glazed window will look different to existing ones. If your existing windows are very old, perhaps 10 years or more, then it’s likely that there will be some small differences.
The first thing to remember is that your double glazing is exposed to the elements as soon as it’s installed. So over time, unless you’re very good at cleaning and maintaining your windows, they’re likely to look a bit dirty. Window frames that are south-facing may also become slightly discoloured from the sun, so if you install a new window right next to it you might notice a difference.
Also, there have been lots of technical advances in windows over the years. If your existing windows are significantly older, you might notice a difference in the handles on openers, and if your existing windows were installed before 2010 they might not have trickle vents, which is an extra strip on the inside of your window to keep air flowing through your home. While it’s not a legal requirement for replacement windows to have trickle vents if the original one didn’t, it’s a good idea to have them installed as they help prevent condensation and mould.
The only truly noticeably different elements to a new double glazed window compared with existing ones are likely to be on the inside, which might not be a problem for you if you only have one window in a room. However, if you know the brand of your existing windows, you can ask your window installer if they can source the same ones. Even if they’ve been updated slightly, the difference should be minimal.
