All properties lose heat through their windows, but there are ways to minimise the loss of heat, as well as the money in your pocket – such as double glazing.
According to the UK Government, around 18% of heat loss happens through our windows.
Heat is lost twice as quickly through single glazing than standard double glazing, around 7% of households in the UK have no double glazing.
Double glazing is an essential way to reduce heat loss and also reduce your energy bills.
Read on to find out more about how much double glazing can save you.
How Much Does Double Glazing Cost?
The price of double glazing can vary widely depending on the design, materials, colours, and window size.
While the price of double glazing may seem high, it is a worthwhile investment for any home with single glazed windows or old double glazed windows.
Why Should You Invest in Double Glazing?
The UK Government states windows with an energy efficiency of A+ is currently the highest rating and will save more energy.
But the savings are not the only benefits of double glazing.
Due to the reduction in heat loss, your home will stay warmer for longer, saving you money on those expensive energy bills.
It can also reduce outside noise and stop condensation from building up on the windows.
Do I Need Planning Permission to Install Double Glazing?
As long as you own the property, you typically don’t need to get planning permission to install unless:
- Your property is in a conservation area
- Your property is listed
How Much Can You Save With Double Glazing?
According to the Energy Saving Trust, by installing A-rated double glazing to windows in an entirely single-glazed semi-detached gas heated property, you could save £135 a year and 380kg of carbon dioxide.
Choosing an Efficient Window
Window manufacturers can show the energy efficiency of their products using an energy rating scale from A+ to E.
The frame, as well as the glass, is assessed to allow for heat loss, draughts and solar gain. This gives a rating that indicates the overall impact of fitting that window in your home.
At Homeshield, our A+ double glazing windows offer the highest levels of insulation and security.
As well as this, we have various different colours and finishes to choose from to fit your taste and style.
You could also save up to £2,500 on our premium windows, as well as doors, when you scrap your old ones.
