This guide to energy efficient windows will explain what makes windows energy efficient. The average UK home loses 25%-30% of its heat through the windows. Installing energy efficient windows can help to lower your energy bills. They can also make your home a much more comfortable place in which to live.
Energy efficient glazing covers both double and triple glazing. These are windows with two or more glass panes in a sealed unit. You can also improve the energy efficiency of your home by installing secondary glazing, or even by using heavy curtains. Having energy efficient windows could help to reduce your carbon footprint and your energy bills.
If you are looking to upgrade your glazing and save a bit of money in the process, then let us take you through the basics of energy efficient double glazing and what you should be looking for in your next windows and doors.
What makes a window energy efficient?
The air gap limits the amount of cold air able to get into your home. It does this by acting as an insulator and is completely sealed.
The space between the glass panes is filled with air or gas such as argon, krypton or xenon. These help reduce heat loss through the unit. A gas such as argon, which has low conductivity, is used within this space. This makes the window even more efficient at keeping heat inside the property. It also interfers with sound waves from inside or outside the house, reducing noise pollution.
Sealed units also have a strip in between the panes, made from metal or polymer. This strip is called a spacer. It contains a drying agent that deals with any moisture trapped in the space between the sheets of glass.
Window materials
It’s not only the glass that needs to be considered but the window frame too. The various materials available all have different qualities and could help to increase the efficiency of your home.
UPVC window frames are an effective insulator, providing your home with an extra layer of insulation, composite, wood and fibreglass frames all have these benefits too. This is in comparison to metal frames, such as aluminium, which is a poor thermal insulator. However, having a thermal break installed within aluminium frames will help to make them much more efficient.
Energy efficient doors
It is not just windows that can help conserve energy, doors can be insulated, and draught proofed to help maintain the heat. As with windows, building regulations state that new doors require approval from the relevant authorities.
Most new external doors should include a draught proofing system, which will help reduce heat loss and prevent the warmth escaping.
Cost
Installed A rated windows around your home will come at a higher price to less efficient windows but you could make back your initial investment through energy bill savings.
The total cost of a new energy efficient window will vary depending on the frame material, size, and style of the window. UPVC is the cheapest window frame material in the UK, one of the main reasons why it’s the most popular, but they will need replacing sooner than aluminium, composite, or timber windows.
