Double glazing explained


The installation or improvement of your double glazing can not only reduce your energy bills, but double glazing can also make your home cleaner, greener, quieter and more thrifty in energy, which means that you do your part for the environment. the advantages of double glazing are simple; double glazing allows you to save money, reduce your energy bills and reduce your carbon footprint.

Save money on your energy bills by replacing all single – pane windows in your home with energy efficient glazing. This could save you about £ 135 a year on your energy bills.

Reduce your carbon footprint by reducing the energy used to heat your home, as less heat escapes through windows. You generate less carbon dioxide (CO2), which causes global warming.

Be more comfortable in your home, because energy efficient double glazing reduces heat loss through windows and reduces the number of air currents and cold. Quiet because in addition to keeping the heat, energy efficient double glazed windows can isolate your home from unwanted exterior noises.

Reduce condensation because energy-efficient double glazing reduces the build-up of condensation inside the windows.

and the savings of double glazing will be different for each house and each window, depending on the size, material and the installer. On average, installing double glazing on your home saves about £ 135 a year on your heating bills, in addition to saving around 720 kg of CO2 (carbon dioxide). Double glazing can help reduce your carbon footprint.

Double glazing can save energy and reduce your energy bills

More than 18% of the heat lost by your home is lost through windows. The heat that is so lost means that energy is wasted and money is wasted. If less heat escapes from your home, you can save energy and save money.

Energy-saving double glazing reduces heat loss and also reduces noise and condensation problems. The energy efficient double glazing installation could result in annual savings of around £ 135 on bills if the single glazing of the house is replaced by an energy efficient double glazing.

All properties lose heat through their windows. Installing energy efficient glazing is an effective way to reduce your energy bills and keep your home warmer and calmer.

Double-glazed windows use two sheets of glass separated by a gap, which creates an insulating barrier. of glass. Both options can provide a high level of energy efficiency. It is not necessary to use triple glazing to get the most energy efficient window.

Energy efficient windows are available in a variety of materials and styles. Their energy efficiency also varies depending on how they prevent the heat from passing through the window, the amount of sunlight flowing through the glass and the little air that can escape or escape. escape from the window.

use a system of energy evaluation of windows to show the energy efficiency of their product. This is similar to what you have seen on appliances such as your refrigerator or washing machine. Windows marked A are the most effective. To check the energy efficiency of a window before you buy it, look at the energy label.

The Benefits

The costs and savings of double glazing will be different for each home and each window, depending on the size, the material and the installer. You could save up to £ 135 a year on your energy bills and up to 720 kg of CO2 per year.

Replacement windows and double glazing come in a range of styles and designs, and there are special features to watch for.

To find the right double glazed windows for your home, ask yourself these questions:

What is the energy efficiency of windows?

When you choose replacement windows, you can check their energy efficiency by looking at the Energy Saving Trust Logo recommended label and BFRC energy label. The Energy Saving Trust approves any double glazed window class C or higher. The higher the energy rating, the higher the energy efficiency. Unfortunately, for the moment, the manufacturers of double-glazed windows have no obligation to label their products, but by opting for a high-quality double glazed window, you know that you will buy the most effectively.

How many layers of glass do you need?

The double glazing has two layers of glass separated by a gap of about 16 mm. There is also the option of triple glazing, which has three layers of glass. Double glazed windows and triple A glazing are available

What type of glass is the best?

Low-E glass is the most energy-efficient glass for double glazing. This often has an imperceptible coating of metal oxide, normally on one of the internal panes – next to the gap. It lets in sunlight and heat but reduces the amount of heat that can come out.

What's in between the windows?

Very efficient double glazed windows can use gases such as argon, xenon or krypton the space between the two glass sheets.

What distinguishes windows?

All double glazed windows are equipped with spacers to keep the two windows separate. For a more efficient window, look for tile spacers that contain little or no metal – often called "hot edge" spacers.

The BFRC energy classification system verifies all components to ensure that the final window meets the claimed energy efficiency standard. This means that you just need to look for the A-G notes and remember that A is the best! Alternatively, simply look for the Energy Saving Trust Recommended logo that is only found on Class C or higher glazing.

Which frame is suitable for your home?

The setting you choose depends on your home and your personal taste. For all frame materials, double glazed windows are available in each energy class.

  • uPVC frames are the most common. They last a long time and can be recycled.
  • Wooden frames can have less environmental impact, but require maintenance. They are often used in conservation areas where the original windows were made of wood.
  • Aluminum or steel frames are thin and durable. They can be recycled.
  • Composite frames have a wooden interior frame covered with aluminum or plastic. This reduces the need for maintenance and maintains the weather-resistant frame

Do you need ventilation?

Because the replacement windows will be more leak-proof than the original plain glazings, accumulate in your home due to reduced ventilation

. There is not enough background ventilation in the room, some replacement windows will have built-in vents in the frame that will let in a small amount of controlled ventilation

. Condensation may occasionally occur outside the new low-emissivity glazing. Indeed, the low emissivity glass reflects the heat in the house and therefore the outer pane stays cool and the condensation can accumulate in cold weather – this is not a problem.

When to improve your double glazing

Most homes now have double glazing, but some people do not realize that double glazing (like anything else needs to be maintained and sometimes replaced if you have had double glazing for several years.)

Haze or condensation inside the glass

If there is moisture in the room Inside the windows, this often means that the sealant has broken, which means that it's time to replace your double glazing. If there is steam and condensation, this is usually the case and the glass will need to be replaced, "says Nick Lowe, of City Windows in Chester

My windows have changed dull yellow

The color change of PVC over time does not mean the quality of the double glazing has been compromised. You can often find specialized paints to repaint the frames of your windows. Most suppliers today guarantee against discoloration, but not minor discoloration and fading.

The hinges on my windows are too tight and it's hard to open the window

If you look at the hinge, you should see a small brass screw. This is the tension screw and if you loosen it slightly, this should solve the problem. If that does not work, your local glass store or your double glazing repair company (see local paper ads or yellow pages) can usually replace the hinge for you. The hinges of my windows are too loose and my windows open wide open

If you look at the hinge, you should see a small brass screw. This is the tension screw and if you tighten it slightly, this should solve the problem. If that does not work, your local glass store or your double glazing repair company (see local paper ads or yellow pages) can usually replace the hinge for you. There is a stream of air passing through my windows

First, check whether there is a loose handle, a slightly bent hinge or a hinge where a screw or rivet it's loose. If this is not the case, you may need to replace your double glazing, although it is helpful to contact your local double glazing repair first to check if you can have the glass repaired. window.

Double glazing can last for years, but anything else is subject to "wear and tear". Before you hire a double glazing company to replace your windows, ask for a few quotes to make sure you get the best deal, and only go with approved and registered double glazing installers, which offer a guarantee.
