Window Installer FAQs

Where can I get one double glazed window?

Most window installers will be able to provide you with one double glazed window and fit it for you. If you’re replacing one double glazed window in your home, ask them to try and source the same windows that you already have or find one that’s very similar. Externally, you probably won’t be able to notice the difference, but if your existing windows are very old there may be some exterior discolouration and the locks and handles might look slightly different.

If you want one double glazed window so you can fit it yourself, there are lots of online companies that can supply you with one window. However, window fitting is a skilled trade and you might want to consider whether you have the right tools and experience to fit it yourself. Of course, you’ll save money on installation costs, but if something goes wrong, you might end up shelling out to get it fixed anyway.

The other thing to consider is that any replacement windows need to be certified that they meet Building Regulations. If you fit the double glazed window yourself, you’ll need to apply to your local council building control officer to get a certificate that confirms that you fitted the window within the regulations. You’ll have to pay a fee for this, and it will be even more expensive if Building Control say that the window hasn’t been fitted within the regulations and you have to start again.

The alternative is to ask a reputable window installer that is registered with a self-certification scheme, like FENSA, to install the window. That means that they can self-certify that the window meets building regulations once they’ve finished the installation.

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.

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 long do double glazed sealed units last?
When it comes to how long double glazed sealed units (the glass inside the window) last, a lot of it is down to the quality of the glass and the environment that your windows sit in. It’s not uncommon for your window frames themselves (especially if they are uPVC) to last longer than your sealed units. Sealed units are called that because they’re two panes of glass sealed together with an air gap in between. They use what’s called a ‘perimeter seal’ to protect the air gap between the panes, and is usually made of butyl mastic which retains a desiccant within a perforated metallic spacer bar. The desiccant’s job is to absorb any moisture which finds its way into the air gap to stop your window from misting up on the inside. When a sealed unit fails, or is ‘blown’, it’s usually because moisture builds up around the seal and causes it to fail. Sealed units won’t last forever, so you will eventually end up with condensation inside the panes of your double glazing, but in an ideal environment your double glazed sealed units could last up to 30 years, with some manufacturers claiming as long as 40 years. But they do require a bit of maintenance and the position of your windows will also make a difference as to how long they last. There are a few things that determine how long a sealed unit will last:
  • Climate - If your window faces south, it will be subject to direct sunlight for a lot of the day. This tends to cause the sealed unit to fail more quickly – a south-facing window may last between 10-25 years. This is because the spacer bars will twist as the temperature rises and causes the adhesive holding them together to eventually fail.
  • Moisture - Windows in kitchens and bathrooms tend to fail more quickly because they come into contact with moisture more often. For example, if water gets on your windowsill when you shower, the seal around the glass will come loose more quickly if it’s constantly wet.
When you replace the sealed units in your windows or get completely new double glazing, make sure you choose an installer that uses quality products and will take all the steps to ensure that your sealed units are kept away from moisture as much as possible.
What is uPVC?

uPVC is unplasticised polyvinyl chloride. It is a favourite amongst homeowners and manufacturers for its cheap production cost and excellent benefits. uPVC is used for window frames, conservatories and doors. In fact, uPVC can be three times cheaper than wooden frames and is also the most energy efficient option.As well as this, uPVC is now available in a range of colours other than the typically seen bright white finish. It can also be recycled, is durable and resistant to changing weather conditions.

how much does double glazed windows cost?

Are you looking to replace your old window for a new double glazed window and wondering what it’s going to be the cost? Well, the double glazed windows market is a very competitive one in the UK with varying prices across the country. Therefore, if you shop around you’re most likely to find something that’ll fit your budget both products and quality wise.

As you would have expected, the more windows you required the more money you are going to spend. However, the cost per window is likely going to be lower depending on the number of windows you purchase. Several double glazed windows come with a 10 year warranty but it’s advisable to also obtain a solid workmanship warranty which provides coverage for any potential problems for a good period of time upon installation.

To determine the cost of double glazed windows, there are so many things to put into consideration that just the primary dimensions of the window itself. Other factors that works to decrease or increase the cost of the project includes the frames’ quality as well as the material used. For example hardwood can be quite high priced when compared to uPVC.

The number of opening windows within the frame can also play a huge role in the cost of the windows as well as the type of the glass. The cost of a double glazing window usually ranges between £100 to £3,200 per window, depending on the available options.

To have a more accurate estimate of the cost of a double glazing window, you’ll need a obtain a survey from a double glazing installer who can take into account any possible complications that may arise when installing your windows while also giving an advise on the most suitable window style for your property.

How to fix a cracked glass window?
You can end up with a cracked glass window in a few ways. The most common one is when a rogue stone in the lawnmower hits the window or someone’s cricket or tennis game goes wrong and you end up with a ball through the window. Youi often end up with a ‘bullseye’ type crack that expands out from the point of impact. You can also get pressure and stress cracks from intense fluctuations in pressure and temperature. Unfortunately, there’s no way you can permanently fix cracked windows without replacing the entire sealed unit. An installer can replace a cracked glass window in less than an hour simply by taking out the sealed unit (the two panes of glass in double glazed windows) and replacing it with a new one. It costs an average of £110, but you could try to do it yourself for around £55. But what if you can’t get an installer to fix your window straight away? There is a DIY method you could try. As a temporary fix for your glass window, you can use a solvent-based adhesive like epoxy which will keep the glass intact and prevent further damage. You’ll also need:
  • Washing up liquid
  • Glass cleaner
  • A lint-free cloth or rag
  • A putty knife
  • A paper plate
  • Acetone
First, you’ll want to clean the glass using the washing up liquid and a damp cloth to remove any dust or oils. Leave it for a few minutes to dry, then create a mixture of epoxy by combining the hardener and the resin and stirring it on a paper plate. Using the putty knife, spread the mixture on the cracks, making sure you press gently to fill them. Leave it for at least 5 minutes to dry, then get rid of any excess by using some acetone on a dry cloth. Clean the window using some glass cleaner and another dry cloth, and you should have a temporary fix!
