Everything you need to know about energy efficient windows

We are much more aware of our carbon footprint than ever before. This is having a positive impact on our buying choices, including the food we eat, the clothes we wear, and how and where we go on holiday. We are also considering energy saving options for our homes and investing in products that are not only good for the environment but also save money.

Heat loss

Energy efficient windows are designed to reduce the amount of heat lost via the windows in our homes, resulting in fewer draughts and no cold rooms.

Noise reduction

In addition to keeping the warm air in and the cold air out, these high specification windows can act as soundproofing in our home.


This type of window is well fitted and offers the added benefit of reducing the build-up of condensation inside the window, even at the coldest times of the year.

Campaigners are encouraging consumers to have a plastic-free Easter this year by checking that the packaging can be recycled before they buy any chocolate gifts. You will find a range of plastic-free options available.

The science

Double glazing consists of two sheets of glass set in the frame with a gap between, which traps cold air. Special types of the frame can be filled with gases, which offers further efficiency. Pane spacers are used to keep the panes equal distance apart.

Triple glazed windows do the same but with three panes of glass. The glass is low emissivity and has an invisible coating that lets light and heat in but not out.


There is a wide range of styles and prices available. These include different frame options; for example, aluminum and steel are long-lasting and can be recycled. Alternatively, you can opt for a wooden frame, which is a better environmental choice but requires more maintaining. Companies that specialize in double glazing Cheltenham offer a wide variety alongside a professional fitting service.

Other options from double glazing Cheltenham include uPVC, which offer longevity and recyclability, and composite frames, which have an internal timber frame but are covered in plastic or aluminum to offer weather protection.

Things to check

Before investing in new windows, check whether there are any restrictions on your property or the area in which you live and get professional advice.
