In today’s world of rising energy costs and growing environmental awareness, the efficiency of your home’s windows has never been more important. Old, poorly performing windows can be responsible for much of your home’s heat loss.
At Aim Windows, we’ve been helping homeowners across London tackle this problem with our range of energy-efficient windows.
Why Energy Efficiency Matters
The Rising Cost of Energy Bills
We’ve all felt the impact of increasing energy prices in recent years. When your windows aren’t performing well, you’re essentially watching your hard-earned money escape through gaps, cracks, and poorly insulated glass.
Energy-efficient windows help keep the warmth where it belongs – inside your home. This means your heating system doesn’t need to work as hard, using less energy and saving you money on your bills.
Reducing Heat Loss and Improving Comfort
Heat loss through windows happens in several ways. Old single glazing allows heat to transfer directly through the glass, while gaps in frames create draughts that let warm air escape and cold air in.
Energy-efficient windows address these issues with better insulation through multiple panes of glass, special coatings, gas fills between panes, and tight seals around frames. The result is a home that stays warmer in winter and cooler in summer, with more consistent temperatures throughout and fewer uncomfortable draughts.
Environmental Benefits
Beyond the financial and comfort benefits, choosing energy-efficient windows helps reduce your home’s environmental impact. The less energy you use for heating, the lower your carbon footprint. With increasing focus on sustainability, making your home more energy-efficient is a practical way to contribute to a greener future.
Adding Value to Your Home
Energy performance is becoming an increasingly important factor for property buyers. Homes with higher energy efficiency ratings are more attractive, often commanding better prices and selling quickly. Installing energy-efficient windows is not just a cost-saving measure but an investment in your property’s value.
Our Energy-Efficient Window Options
At Aim Windows, we offer a range of energy-efficient window solutions to suit different property styles, budgets, and requirements.
UPVC Windows
Our uPVC windows combine excellent thermal performance with affordability, making them, often, the most popular choice if energy efficiency is the focus. They feature:
- Multi-chambered frames that use air pockets as natural insulators
- A-rated double glazing as standard
- Argon gas fills between the glass panes
- Available in over 30 colours, including woodgrain effects
UPVC is naturally resistant to heat transfer, creating multiple barriers against heat loss to help keep your home warm and your energy bills down. Our uPVC sash windows are particularly popular in London’s Victorian and Georgian properties, where maintaining character while improving efficiency is important.
Aluminium Windows
Aluminium carries a reputation for poor energy efficiency, but our modern aluminium windows incorporate advanced thermal break technology that prevents heat transfer through the frame. Our aluminium windows offer:
- Slim frames that allow for larger glass areas
- Thermal break technology to prevent heat loss
- Any RAL colour option for perfect customisation
- 100% recyclable material for sustainability
The strength of aluminium allows for slimmer frames and larger glass areas compared to uPVC, giving better views and a more modern look.
Secondary Glazing
For homes in conservation areas or listed buildings where replacing windows might not be possible, secondary glazing offers an excellent solution for improving energy efficiency without altering the external appearance.
Our secondary glazing involves fitting a separate, internal window to your existing windows, creating an insulating air gap that:
- Reduces heat loss by up to 70%
- Eliminates draughts and cold spots
- Maintains the original character of your property
- Requires no planning permission in most cases
This makes it particularly valuable for homeowners in London’s many conservation areas.
Double and Triple Glazing
All our windows come with high-performance glazing options:
- Double glazing as standard
- Triple glazing available for maximum thermal efficiency
- Argon gas fills between panes for superior insulation
- Low-E glass coatings that reflect heat back into your home
- Warm edge spacer bars to reduce heat loss around the edges
Our glazing units achieve U-values as low as 1.2 W/m²K with double glazing, and even lower with triple glazing options. This significantly outperforms older systems and translates directly to lower heating bills.

Frequently Asked Questions
How much can I save on my energy bills with new windows?
While savings vary depending on your current windows, property type, and heating system, many homeowners report 10-25% reductions on their heating bills after installing energy-efficient windows. The older and less efficient your current windows, the greater the potential savings.
How long do energy-efficient windows last?
Our uPVC windows have a lifespan of up to 35 years, while our aluminium windows can last up to 45 years with minimal maintenance. Both options are designed to maintain thermal performance throughout their lifespan, providing long-term energy savings.
Will installing new windows cause much disruption to my home?
Most window installations are completed within a day for an average home, with minimal disruption. Our experienced fitters work efficiently and clean up thoroughly afterwards, ensuring the process is as smooth as possible for you and your family.
