Are you tired of high energy bills and cold rooms? It might be a great time to consider new windows. At Aim Windows, we know how energy-saving windows can improve homes in East London. Let’s look at how new windows improve your home’s energy efficiency.
Improved Insulation
One of the key ways that new windows save energy in your home is by improving insulation. Modern double glazing is far superior to single glazing or old double glazing. Our windows are fitted with high quality glass from Glass Systems Ltd, which keeps heat from escaping. This means your home stays warm in winter and reduces your energy use.
Lower U-Values
A U value measures how well a window keeps heat inside your home – the lower the U-value, the better the window is at preventing heat from escaping. Our windows achieve U-values as low as 1.2 W/m²K, far lower than older windows. This better performance means you need less energy to keep your home warm. This reduces your carbon footprint and lowers your heating bills throughout the year.
Modern Advanced Glazing
Today’s double glazing and windows use modern technology to improve their performance. Our windows include:
-
- Low emissivity (low-E) coatings that reduce solar gain.
- Argon gas fills the gap between the panes of glass to improve insulation.
- Strong seals that prevent moisture and energy loss and keep the inert gas in place.
- Warm edge spacer bars reduce heat loss around the edges of the glass.
Frame Materials Matter
The material you choose is an important consideration that can significantly impact how energy efficient your windows are. At Aim Windows, we provide:
-
- Multi-chamber designs provide excellent insulation
- Requires little maintenance
- Comes in more than 30 colours
uPVC windows are naturally resistant to heat transfer, making them one of the most thermally efficient frame materials. Its multi-chambered design creates multiple barriers against heat loss, helping to keep your home warm and reduce the amount of energy you use.
-
- Smart thermal break systems for better efficiency
- Slim sightlines for more glass space
- Any RAL colour you want
While aluminium is naturally conductive, modern thermal break technology creates an insulating barrier within the frame, significantly improving its thermal performance. This innovative design, combined with slimmer frames and larger glass areas, creates stylish and energy-efficient windows.
Reducing Draughts
Old windows can let in cold air through smaller gaps and cracks in the frame and glazing. This can force your heating system to work harder to compromise. Our new windows come with better seals and weatherstripping, which helps prevent draughts and creates a fully sealed unit. Their design keeps your home comfortable by removing cold spots. It also eases the burden on the heating system and gives you better control over your home’s temperature.
Energy Ratings: A Clear Guide to Efficiency
Window Energy Ratings (WERs) provide a simple way to understand how energy efficient a window is. To give an overall thermal efficiency score, these ratings consider several factors, such as heat loss, air leaks, and solar heat gain. At Aim Windows, we’re proud to offer ‘A’ rated windows as standard, meaning they achieve high energy efficiency. This superior rating ensures your windows will effectively maintain your home’s temperature while helping to reduce your energy bills.
Secondary Glazing
Secondary glazing is an excellent solution for homes where you can’t replace the windows completely, such as conservation or period properties. Secondary glazing adds a single glass pane to your existing windows, creating a layer of air that helps insulate. Secondary glazing keeps your home warm without changing its appearance from the outside.

Frequently Asked Questions
Q: What makes a window energy-efficient?
A: Energy-efficient windows use features such as low-emissivity (Low-E) glass, double or triple glazing, insulated frames, and airtight seals. These elements work together to reduce heat loss and help maintain a comfortable indoor temperature.
Q: How much can I save on my energy bills by upgrading my windows?
A: Savings depend on your current windows and the type of home you live in. Many households see noticeable reductions in heating costs after replacing old single-glazed or poorly performing windows. The bigger the improvement in insulation, the higher the potential savings.
Q: Which frame material is best for energy efficiency?
A: uPVC offers strong insulation and low maintenance, aluminium provides strength and modern styling when paired with a thermal break, and timber or composite frames offer natural warmth. The right choice depends on your budget, design preference, and performance needs.
Q: Is triple glazing better than double glazing?
A: Triple glazing provides improved insulation and noise reduction compared to double glazing. It can be a good option for colder areas or homes near busy roads. However, high-quality double glazing still delivers excellent performance for most properties.
Q: What should I look for when choosing energy-efficient windows?
A: Key things to consider include:
-
U-value (lower values indicate better insulation)
-
Glass type and coating
-
Number of glazing layers
-
Quality of seals
-
Frame material
-
Professional installation to prevent draughts
Q: Can energy-efficient windows improve comfort?
A: Yes. They help reduce cold spots, minimise draughts, maintain more stable temperatures, and limit condensation. This creates a more comfortable living environment throughout the year.
Q: Will new windows add value to my home?
A: Upgrading to modern, energy-efficient windows can make a property more appealing to buyers. Better thermal performance, improved appearance, and reduced running costs are attractive selling points.
Q: How long do energy-efficient windows last?
A: Most high-quality windows last for decades when maintained well. Routine cleaning, checking seals, and keeping hinges and locks in good condition will help preserve their performance over the long term.
