Are You Losing Heat Through Inefficient Windows?
Thursday, December 1st, 2011If you are looking at ways to improve the energy efficiency of your home then you should look at the windows that you have installed to ensure that they aren’t losing you heat and costing you more to heat your home.
Up to 25% of your current energy bill can be saved by preventing loss of heat through outdated windows and doors, so by ensuring that your windows are energy efficient it will mean that substantial cost savings can be made on both heating and lighting costs.
But how can you tell if your windows are energy inefficient or not? If you have single glazed then they are likely to be inefficient compared to double glazed windows. However, the main tell-tale sign of inefficiency is a high fuel bill.
Why not check your windows and make an evaluation of their efficiency by carrying out a simple draught test? This test involves holding a lit candle to the window and seals to see if the flame bends or flickers. If the flame does this can be a sign of a draught.
If you do have a draught you can either seal the draught or consider replacement windows if you feel they are outdated and need updating. If you decide to replace the windows then it will be important to install the best energy efficient windows to reduce your energy bill.
To do this you firstly need to research the windows and check their BFRC Window Energy Rating (WER). This energy rating looks at a whole spectrum of relevant energy saving factors such as heat gain and heat loss factors so is a good indicator on how efficient the window is. Energy rating runs from A-G and this is a similar rating scale to that used for white goods and appliances. Some windows also come with Energy Saving Trust recommended logo, so it is important to look out for this as well.
Secondly, consider the glass that is used in the windows and remember that the most energy efficient double glazing glass is low emissivity (Low-E) as it lets in light and heat but ensures that less heat escapes through the glass. Also see what is between the double glazed panes as some windows use argon, xenon or krypton to make the windows more efficient.
Finally, understand that the type of frame that you select will affect the energy rating of the window. For example, uPVC frames are known to last longer when compared to wooden frames that will require maintenance over time.
By installing energy efficient windows in your home then you will start to see the benefits immediately and start to recoup the money that has been outlaid to install the windows. Benefits that will be experienced include smaller energy bills, a more comfortable and warm home, fewer draughts as well as a reduction in condensation and noise from the outside.
You will also be reducing your homes carbon footprint and therefore playing a part in becoming an environmentally friendly household. If the outlay seems expensive then it is important to remember that double glazing can last up to 20 years and you need to consider the amount of savings that you can make in this time.

Solar PV stands for solar photovoltaic and is a technology that converts sunlight (even on a cloudy day) into electricity. Solar PV comes in the form of solar panels that are installed on roofs and walls and these solar panels are installed with photovoltaic cells that do the conversion.
