uPVC Window Energy Saving
How uPVC windows can save you money:
There are a number of improvements that can be made to your home to help to bring energy bills down. One thing you can do is to install uPVC windows, which has a number of related benefits. Below is some information on how they help you to make those important savings.
1) DOUBLE GLAZING IS AN IMPORTANT FACTOR
Double glazing can play an important role in reducing energy bills, and is one of the most important factors when it comes to the increase in a window’s energy efficiency. There are a number of reasons for this. High-quality double glazing is able to create a significant sealing within the window frame to reduce draughts. Single glazing is often a major cause of energy loss, as it is just not as efficient, so it prone to draughts and general issues which can cause a higher energy bill when compared to double glazing.
2) A GOOD INDICATION OF ENERGY EFFICIENCY COMES FROM WINDOW RATINGS
When it comes to choosing some uPVC windows, be sure to check out the ratings. The WER is used to show how energy efficient a window is. There is a range of factors considered, relating to the air output (L-value), solar gain (G-value) and heat retention (U-value). The ratings range from E to A+, with B being the minimum requirement. These ratings balance the positive gained from the G-value with the more negative factors of the L-value and U-value to come to an overall formula-based conclusion.
3) DRAUGHT-PROOFING CAN HELP REDUCE ENERGY BILLS
Double glazing tends to excel when it comes to excluding draughts. There are still things you can do to imrove the energy efficiency. Draught-proofing in general is a cost-effective way of ensuring you plug any gaps. Just some simple extra draught-proofing around your uPVC windows and doors can save you a tidy sum on your energy bill. One way to improve ventilation is through the use of trickle vents. These are small openings in a window that allows air to pass through the window, offering fresh air without the need to open the window. This design has additional benefits including noise reduction and increased security, given that you don’t have to open your window for ventilation.
4) THE TYPE OF GLASS USED IN UPVC WINDOWS
A good way to prevent heat from escaping to the outside is to use Low-emissivity glass (low-e), UPVC windows. The window energy rating (WER) will improve as a result. The low-e glass works by having an exceptionally thin coating on the side of the internal surface of the glass allowing it to reflect heat back into the home as well as letting in more light. Air can sometimes be used in between each pane of glass as an insulaotr. Adding an inert gas like argon, which is denser than air, can help boost energy efficiency. This, combined with the low-e glass, can significantly improve the performance of your uPVC windows.
