If you’re worried about the cost of energy this coming winter, equipping your home with energy-efficient windows can be a smart solution. Not only will you see a difference in your heating bills, but you’ll also be making your home more eco-friendly. Draughty windows with old double glazing are responsible for up to 20% of heat loss in a home, so upgrading to energy-efficient windows is one of the most effective ways to eliminate draughts, let out less heat, improve your home’s energy performance, reduce your carbon footprint, and save money – all at the same time.
How can I stop losing energy through my windows?
Upgrading your windows from single glazing or older double glazing, which will be letting out too much heat from your home, can significantly increase your thermal efficiency and reduce energy waste. Consider high-performance options like double or even triple glazing, or add secondary glazing for an extra layer of efficiency in a single sealed unit. These technologically-advanced windows act as thermal barriers, trapping warmth inside during winter while keeping the cold at bay. In warmer months, they cleverly utilize sunlight without letting excessive heat enter, preventing unwanted heat transfer and keeping your home pleasantly cool. The result? A comfortable living space and a significant reduction in your energy bills.
How does the type of glass affect window energy performance?
When it comes to energy-efficient windows, the type of glazing you choose can make a significant difference, as it has a direct impact on how your windows perform. Not only will glazing affect how much natural light illuminates your home, but it also plays a crucial role in keeping heat in or out. Remember, sunshine can heat up a space too.
How do different types of frame affect window energy performance?
Don’t underestimate the impact of your window’s frame material on energy efficiency. uPVC windows, for example, are champions in this category. Their five-chambered insulating profiles act like tiny heat stoppers, thanks to their low thermal conductivity. uPVC replacement windows also do not require regular maintenance to keep them performing as good as new for years to come. Modern aluminium frames have also come a long way, incorporating internal thermal breaks to boost their energy-saving potential.
Choosing the right window glazing – the options.
Double Glazing: The Classic Choice
For many UK homes, double glazing is the gold standard. It’s the most popular option for a reason: it offers excellent thermal performance at a reasonable price. Think of it as the workhorse of window insulation, keeping your home warm in winter and cool in the summer months thanks to the air gap between its two panes.
Triple Glazing: Efficiency Champion
Triple glazing with a third pane of glass ups the ante with three panes instead of two, creating an extra layer of insulation. This translates to superior energy efficiency, ideal for those seeking maximum thermal performance. It’s important to note, however, that this added efficiency comes at a higher cost.
Comfort Glass: All-in-One Protection
For properties facing harsh weather or noise pollution, Comfort glass might be your ideal choice. This advanced option, which has a slightly higher additional cost, combines two high-performance panes with a special laminate layer and a Low-E coating. This dynamic trio works together to trap heat inside, reduce noise, and even block harmful UV rays from solar energy.
Secondary Glazing: A Compatible Complement
Living in a conservation area or a listed property with restrictions on window alterations? Secondary glazing offers a solution. It’s essentially an additional layer of glass installed on the inside of your existing windows, providing a valuable boost to insulation without altering the exterior look.
Triple Glazing v Double Glazing:
Don’t be fooled by the misconception that more panes of glass always mean better. For many homes, high-performance double glazing, like Comfort Glass, can be just as effective as triple glazing and less glass panes. Comfort Glass boasts specially coated glass that provides the same level of insulation as triple glazing, but with some bonus benefits. This innovative option offers enhanced security, superior energy efficiency, and impressive noise reduction – all without the extra cost of triple glazing. Smart Low-E coatings act like a one-way door for heat, trapping it inside and preventing unwanted escape. Plus, it shields your home from harmful UV rays.
Will I save much by replacing my windows?
The price tag on double glazing can vary depending on the materials and style you choose. uPVC windows tend to be more budget-friendly, while aluminium frames come with a higher price point. But regardless of the option you select, upgrading your old windows to modern, energy-efficient models can significantly reduce your heating bills. The Energy Saving Trust estimates that installing A-rated double glazing in a typical single-glazed, gas-heated semi-detached home could translate to savings of £145 per year and a reduction of 335kg of carbon dioxide emissions. Upgrading to A++-rated double glazing could boost those savings to £175 annually and cut carbon emissions by 410kg. That’s a win-win for your wallet and the environment.
Decoding Window Energy Ratings (WER):
When shopping for windows, look for the Window Energy Rating (WER) sticker. This rainbow graphic displays the window’s energy efficiency on a scale of A++ (most efficient) to E (least efficient). The WER considers the entire window unit, including the frame and glass. It factors in heat loss, air leakage, solar gain, and UV heat transfer to provide an overall picture of the window’s impact on your home’s energy performance. For maximum energy savings, prioritize windows with an A+ rating, which indicates they allow more heat gain than they lose. Remember to check for the British Fenestration Rating Council (BFRC) rating for verification.
What is a U-value?
While window energy labels display U-values, it’s important to understand they’re just one piece of the puzzle. U-value measures heat transfer through a material, but for a more complete picture of window efficiency, look at the overall label rating.
Think of it like judging a book by its cover – the U-value might be low, but other factors like glass type, gas fill, and spacer bars all play a role in heat transfer. The lower the U-value (ideally 1.4 or below), the better the insulation and the warmer your home will be.
