Why install double glazing?

All properties loose heat through their windows. Energy-efficient type of windows, such as double glazing, keeps your home warmer and quieter. Less energy to heat your home means you can save money on your energy bills.

What are the benefits of having double glazing installed?

What should I consider when installing double glazing?

The type of glass

The most energy-efficient type for double glazing is low emissivity glass. Very efficient windows might use gases such as argon, xenon or krypton in the gap between the sheets of glass.

Frame materials

The materials used for the frame can be different. You can choose between UPVC, wooden, aluminium, steel or composite. Talk to our energy efficiency advisors for more information on what type of double glazing is the most suitable option for you.

Energy rating

Some window manufacturers show the energy efficiency of their products using an energy-rating scale from A to G. The ratings are based on the product’s efficiency at retaining heat.


Inefficient windows contribute to condensation build up due to the reduced ventilation. For more information on how to tackle damp and deal with ventilation talk to one of our energy efficiency advisors.

Living in a conservation area

If you live in a conservation area or in a listed building there may be restrictions on what you can do to your windows. Check with your local council to see what options are available to you.

I was really impressed by the way Infinity Energy Organisation handled me and carried me as a customer and carried out the External Wall Insulation on my property. With only keeping my heating on for a couple of hours a day this has made my house much warmer and has reduced my energy bills. With their friendly and helpful staff and installers Infinity Energy kept me regularly updated on the next stages.
