Double glazing

uPVC double glazed windows supply & fit

If you want to see a huge reduction in your annual energy bills, whilst being environmentally friendly, replacement double glazing is often the way to go. And with uPVC windows you have a material that surpasses aluminium and hardwood, with a number of quality benefits.

uPVC double glazing is the most popular window replacement in the UK and is even recommended by most window installers because of its advantages.

But what is double glazing?

Double glazing is an efficient window unit that will replace your old, inefficient single paned windows. It’ll last for more than 15 years, cutting your energy bills year-in year-out by retaining heat in your home.

It works by having two panes of glass separated by an energy efficient spacer, which doesn’t allow heat to pass through. This spacer is normally Argon and fills a gap between 20mm and 28mm.

Benefits of uPVC double glazing

uPVC windows are the most popular replacement units in the UK and thousands of installations are completed every year. With double glazed windows:

  • Reduce your heating bills by as much as £300 a year, with superb energy efficiency locking heat in your home. This means you don’t need to turn up the temperature on your boiler to keep warm.

  • Your property instantly becomes more secure and research actually suggests break-ins are prevented as burglars avoid double glazed properties. Double glazing helps put your mind at rest and ensures greater safety.

  • Cut your home’s carbon dioxide emissions, lowering your footprint on the planet. Carbon is one of the key gases responsible for environmental problems such as global warming.

  • And an added benefit with double glazing is that noise pollution is limited, with sound waves unable to pass through that efficient Argon spacer.

Why choose uPVC windows?

There are a number of reasons uPVC is the most popular frame material in the double glazing industry for both homeowners and companies. Firstly, it’s far cheaper than hardwood or aluminium. So for those on a budget it’s a life saver.

And even with the cheap price, uPVC doesn’t skimp on its quality. It’s an extremely efficient material, reducing your energy bills and is also extremely durable and resistant to weather conditions.

It won’t rot or bow like wooden frames and it also can be coloured to match traditional homes. During production it’s created with stabilisers and additives to protect it from the sun’s natural UV rays too.

Double glazing FAQs

What is the Window Energy Rating (WER)?

The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.

How to fit a double glazed window?

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.

What happens to my old windows?

After fitting your new windows, your installer should take away and dispose of your old windows. If you want to keep them, just let your installer know before they start work. The UPVC frames are melted down and used on the unseen parts of new windows. Aluminium frames are re-smelted and wooden are broken down and used as chipboard.

How much could I save on my energy bills if I install double glazing?

As well as keeping your home warmer and reducing noise, you’ll notice a saving on your energy bills from installing double glazing. If you install A++ rated windows in your home after having single glazing, you could save up to £120 year on your energy bills. The Energy Saving Trust has more information.

Should I use a Fensa registered installer?

Using a Fensa registered installer isn’t compulsory but it helps to protect you from cowboys and rogue traders. It will also make life a whole lot easier in regards to Building Regulations. Replacement windows must meet a certain energy efficiency rating and once fitted you need a certificate to show your installation complies. By using a Fensa registered company they’ll issue this certificate, otherwise you’ll need the council to look at the new windows.

What are the other double glazing options?

Double glazing frames don’t just have to come in uPVC and are available in other materials including aluminium and wood too. Wooden or timber windows are more suited to properties with a traditional look and are often the frame of choice for listed buildings and homes in conservation areas. When properly maintained wooden windows can last well for years but can be up to three times more expensive than uPVC.Aluminium is the strongest and most durable option. As a metal it is highly resistant to the UK’s changing weather conditions and won’t rust, warp, crack or peel. Aluminium offers a modern appeal and is available in a range of colours.

Should I get all my windows replaced at once?

You don’t have to, especially if you’re on a budget. If you’re only replacing some, it’s a good idea to get all the windows on one side of your property replaced at the same time, so they all look the same. Be aware, obviously, huge savings could be had by having a number of windows replaced at the same time.

What is a window sash?

Windows, being a very crucial feature in every home, are one of the things you simply can’t afford to ignore in your home. Having a good understanding and solid knowledge of your windows’ components like the window sash will help you stay up to date with them and able to identify any minor mishaps early on before it leads to a much bigger problem. So what exactly is a window sash?

Well without much fuss, a window sash is simply that part of your windows that’s able to open and close. And there could as well be more than one window sash that’s operable depending on your window’s type. Window sash usually possess a very basic design as well as structure. What’s more? This section of a window happens to be a frame that’s designed in such a way to make for easy placement inside the whole window casement. You’ll discover inside the sash frame, the window glass alongside any framework possessed by your window which includes grids.

Usually, the sash is fitted into the frame of the window on a runners’ set in such a way that allows for both upward and downward movements. And finally, the window sash’s frame typically comes with a locking system which provided for extra safety and security.

The window sash is a vital feature that can determine the durability and overall performance of the windows. In the event whereby your window sash is malfunctioning, it can result to numerous problems which includes both drafts as well as leaks. As a result, it’s very important to keep your window sashes in a great working condition as failure to do so will make opening and closing your windows a really difficult task.
