The subject of energy saving is one that continues to raise questions, with people continuing to look for answers. There are a number of home improvements that can be made to a property to help to reduce energy bills. One of those is the addition of uPVC windows, which have several related benefits. They are a great budget-friendly option to increase the efficiency of your Sheffield property. Here are some ways in which they allow you to make those important savings.
One of the most important and influential factors when it comes to the increase in a window’s energy efficiency, double glazing can play a key role in reducing energy bills. There are a number of reasons for this. High-quality double glazing is able to create a significant sealing within the window frame to cut draughts. Single glazing is often a problematic glazing source, as it is simply not as efficient. It is therefore prone to draughts and general issues which can cause a comparatively higher energy expenditure.
Using low-emissivity glass (low-e), uPVC windows are able to prevent heat from escaping to the outside. The window energy rating (WER) will improve as a result and can considerably reduce the amount of energy that would otherwise be lost through your windows. The low-e glass works by having an exceptionally thin coating on the side of the internal surface of the glass. With that, it is able to reflect heat back into the home as well as letting in more light.
The gaps in between the glass is a key component of double-glazed uPVC windows. The size of the gap can often influence the overall performance of the windows. It is not necessarily a case of ‘bigger the better’, with 16mm often seen as the ideal. However, smaller can also be better in certain scenarios.
While air can sometimes be used in between each pane of glass, adding an inert gas like argon gas can significantly improve the performance of your uPVC windows. The argon gas is denser than air and, combined with the low-e glass, can regulate your home’s temperature.
While double glazing, especially when new, tends to excel when it comes to excluding draughts, there can still sometimes be issues. Draught-proofing in general is a budget-friendly way of ensuring any gaps are plugged. Just some simple extra draught-proofing around your uPVC windows and doors can save you around £25 a year. 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, thus offering fresh air without the need to open the window. Additional benefits to this design include noise reduction and increased security, given that you don’t have to open your window for ventilation.
Look out for some ratings when it comes to choosing some uPVC windows. 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 BFRC ratings range from E to A++, with C 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.
