Are My Windows Energy Efficient? (Quick Guide)

Sometimes it can be difficult to understand what energy ratings are, but really it’s quite simple. When we buy electrical appliances, such as fridges or cookers, we look at and heed the energy performance rating to check the efficiency of the product and how much it costs to run. A fridge with a ‘G’ energy rating can often cost up to £100 more per year to run than an A+ rated fridge, so providing that it looks good, is the size you want, & is reasonably priced we would all tend to buy the A+ rated fridge, it’s just good common sense, isn’t it?

It’s just the same with the modern windows, only more so! Therefore in the same way that you check out an electrical appliance you should follow the same guidelines when evaluating the efficiency and cost savings that you can make by choosing the best-rated windows that your pocket will allow, because the saving that you can make on heating costs will help pay for the windows in very quick time.

Read our 4 tips to checking your window efficiency:

1. Check your windows for draughts or air leaks

You may be losing heat from draughts, so to check this, close all windows and doors, then hold a lit incense stick next to the windows where you suspect draughts may exist. The movement of the smoke from the incense stick will show you if air is leaking through your existing window frames.

2. Do you have old fashioned single pane windows?

If the glass in your existing windows is only a single pane not only will the temperature outside adversely affect the inside of your home, but you will also be heating the outside because a single 4mm pane of glass will let up to 70% more heat escape through than an A+ double glazed.

3. What type of frames do you have?

It is important to understand that certain types of frames and frame materials are less efficient than others, for example Timber and metal frames are by far the least energy efficient, because with timber it will expand and contract with weather changes, and with metal it is by nature a cold product therefore does not perform well on energy efficiency and could even encourage condensation.

UPVC frames are far and away the most energy efficient due to their low conductivity and with the best designed PVCu frames the transference of temperatures from outside to inside or from inside to outside is almost non-existent.

4. Check the Energy Rating

Clearly not all PVCu windows are the same, so make sure that you have the most energy efficient windows possible. It is essential to have A+ rated windows to help you lower your energy bills and to improve the comfort of your home. ‘C’ rated windows will do, but to have A+ rated windows installed by South Coast Home Improvements will cost you no more, but will save you ££££’s.
