Energy Efficient Windows
Are you looking to get some brand new, thermally efficient and energy-saving windows for your property? Finding the right kind of windows can go a long way not to just protect your home and make it look great, it can also help you reduce your heating bills, keeping your home warmer for longer and can even help to reduce your overall carbon footprint.
Double glazing continues to be the most popular glazing option for windows and doors for homeowners all across the UK, and for good reason. Made up of two separate glass panels, separated by a gas-filled vacuum chamber that gives it a thicker profile to prevent heat from passing through to the outside so easily, trapping it within your home and keeping it warm throughout the winter.
Energy Efficient Windows UK
Getting a window that is not just aesthetically pleasing, but which provides your home with efficient insulation and a strong sense of security not only helps you save money on your heating bills and decreases your carbon footprint but can also increase your houses’ overall value should you decide to sell on at some point in the future. Whether you live in a traditional, period home or a modern, contemporary build, there are dozens of different style options available to you to ensure that your new windows will match both the outside and inside of your property.
Energy-efficient windows are highly sought after in many homes. They make the property more comfortable to live in, block noise from outside and even help to reduce the levels of condensation inside the windows, which can help reduce the risk of damp. To achieve the highest quality windows available, you don’t have to just find the right design but also find the best installers.
No matter how good your window is, if it is poorly installed it will prove inefficient and still lose a lot of the internal heat you were hoping to save. A good quality installation will maximise the lifespan of your windows, ensure of a secure fixture that is difficult to break and leaves a strong thermal seal that prevents any heat from escaping.
Which Windows Are Most Energy Efficient?
Float Glass – The standard glass for double glazing and named after its manufacturing process of floating molten glass in a bath of liquid metal, float glass is durable, difficult to break and very long-lasting.
Tempered Glass – Put through a chemical or thermal treatment, tempered glass is far stronger than float glass. In the unlikely event of a breakage, the glass will crumble instead of shatter, making it easy to dispose of with no sharp, dangerous edges, making it a good choice for anyone worried about the risk of broken glass.
Self-Cleaning Glass – Perfect for hard to reach windows and skylights, this glass is covered in a titanium oxide coating that breaks up any collected dirt and allows it to be easily washed away by the rain.
Laminated Glass – Otherwise known as ‘safety glass’, laminated glass is tougher than both float and tempered glass, with a layer of ethyl vinyl acetate or polyurethane laid underneath both panes. This means that, if the window was to break, the glass would hold its place instead of falling out, preventing anyone trying to break in from climbing through any holes in the window.
Fireproof Glass – Able to withstand temperatures as high as 871°C (1,600°F) and close proximity to fire from between 30 to 180 minutes, fire-resistant glass allows you longer to escape and for the blaze to be tackled before it breaks.
Coated Glass – Also known as ‘Low E’, this glass is covered in a Pyrolytic coating to give it increased durability and strength, and higher levels of thermal efficiency to trap heat inside your home.
A Rated Windows
It has been a requirement since 2010 that all windows sold in the UK must have a minimum energy rating of C, to help reduce our impact on the environment.
Energy ratings are measured from G to A+; the higher the ranking the more thermally efficient the window is. A was originally considered to be the highest rating for windows, but improvements and advances in manufacturing techniques and window design have meant that some windows have exceeded that standard, being given a rating of A+ or even A++.
While the higher-rated windows are typically more expensive, the higher the rating you gate the better as these windows help you save money on your heating bills, helping them to pay for themselves over time. If you are concerned about your budget, shopping around can help find the best price, which you can do by using our free online cost calculator to get in touch with a number of reputable installation companies operating within your local area.
Which Doors Are Most Energy Efficient?
Fibreglass Doors – Being a poor conductive material for both heat and electricity, fibreglass slows down the transference of heat from the inside to the outside, giving it superb insulation and preventing large amounts of heat loss.
Vinyl Doors – Made from MDF and wrapped in a vinyl outer layer, these doors are incredibly thermally secure and helps to lock the heat from your central heating within your home.
Steel Doors – While steel is a conductor for heat, steel doors are still very energy efficient as the thermal break within the door prevents the layers of steel from touching one another to pass the heat through. This can mean that you can feel the cold when touching the door, it won’t allow the cold to enter your property.
Wooden Doors – While it is a traditional option, wooden doors are not very thermally efficient, absorbing heat and allowing cold air to get in from the outside. For added thermal insulation, wooden doors can have their core filled with polyurethane foam to prevent heat transference.
Glass Doors – If you want a glass pane in your door, choose double glazing to help prevent heat loss. Low-E or coated glass is also a great option for external doors.
How Can I Make My Window More Energy Efficient?
If you already have windows installed and want to increase their thermal insulation and efficiency, there are a few ways of doing this without requiring a whole new window to be fitted.
Upgrade to double glazing – Secondary glazing can be fitted onto pre-existing windows, through the installation of a second pane of glass and gas-filled vacuum between them.
Seal the gaps – Unsealed gaps and breaks in the frame can allow cold air to enter and warm air to escape, so filling them with caulk, weather stripping or another sealant (depending on the material of the frame) can prevent this from occurring. Buyable in all good hardware shops, ask around if you are unsure of what type of sealant to use for your particular windows.
Get curtains – Heavy curtains can help to block out cold air getting in through the windows, as well as keeping any heat from escaping, especially in the winter months. Thermal curtains are specially designed for this purpose, but blinds and other hangings can also be used to great effect.
Get window film – Easily found in many hardware shops and easily installed yourself, window film adds an extra layer of thermal protection to the glass of your window. With clear options to not impede your view outside, these films are also available in many different patterns and frosting effects for additional privacy.
Is Triple Glazing Cost Effective?
While double glazing continues to be the most popular glazing option on the market for both windows and doors, triple glazing is becoming increasingly well known as a thermally efficient alternative upgrade.
While double glazing utilises two separate panes of glass, separated by a gas-filled vacuum chamber to increase the thickness of the window and prevent heat transference, triple glazing adds a third layer of glass and an additional second vacuum chamber. These added layers are able to trap heat more effectively within your home and is also far stronger than double glazing.
While double glazing costs around £350 for a single window, triple glazing will cost somewhat more, at around £500 per window. If you are working to a tighter budget, this increase may seem a little steep, but with the added insulation it will help save you money on your heating bills and can, in fact, help to pay for itself over the years.
