Improve Thermal Efficiency
Our A-rated, A+ and A++ rated energy efficient windows improve thermal efficiency and helps keep your home warm. They make the most of solar energy and prevent warm air escaping. This helps you maintain a comfortable temperature in your home all year round.
Reduce your Carbon Footprint
Energy efficient windows reduce the amount of energy you use. Your home loses less heat, meaning you use your heating less, lowering your energy consumption. Using less energy means you produce less CO2, and saves you money on bills too.
Less Condensation
Condensation forms on windows when moist air meets cold glass. Spacer bars between the panes create a thermal break, preventing inner glass getting too cold. Low-E glass reflects heat back into your room, keeping inner panes warm in warm rooms. These features in our windows reduce the risk of condensation forming.
Add Value to your Home
A low score on an Energy Performance Certificate could lower the chances of selling your house. A Government report on property sales found making energy saving improvements could increase the value of your home by 14-38%. Upgrading your windows can increase your score, lower your bills, and add value to your home.
More Cost Effective
New windows often have higher window energy ratings than old ones. Replacing pre-2002 double glazing with our A-rated double glazing could save you £184.25 per year* on energy bills. uPVC A-rated windows are also more cost-effective compared with Aluminium and Wood, saving you money in the short and long term.

How much difference energy efficient windows make, depends on how high their energy rating is. They can help you save on your heating bills, how much depends on other factors like the size and type of home you have. They can help you maintain the warmth of your home in winter months, and how much heat your windows let in during summer months. They can also help you use less energy, reducing your carbon footprint. Replacing your old double glazing with double glazing with an A+ energy rating could help you reduce your carbon usage by 140kg per year*.
