Did you know a home typically loses 18% of its heat through windows? While there are ways to insulate other parts of the home, like the loft or cavity walls, it can be challenging to prevent heat loss through windows.

Quick Facts: 

  • A home loses 10% of its heat through windows.
  • Efficient windows require knowledge of thermal performance dynamics.
  • Energy balance = solar heat gain – heat loss.

How much money do energy-efficient windows save?

Energy-efficient windows can save money on heating costs, with a typical gas-heated semi-detached house potentially saving around £120-155 per year. Savings may vary depending on the specific home.

What are energy-efficient windows?

Energy-efficient windows have multiple panes of glass in a sealed unit, such as double or triple-glazed windows. The extra glass helps prevent heat from radiating through the window, making them more efficient.

Why are double-glazed windows energy efficient?

Double-glazed windows are energy efficient because they have an additional layer of glass with a gas, such as argon, injected and sealed between the panes. This prevents heat from radiating out during colder months and keeps the home cooler during summer months, resulting in less energy consumption.

What is a good window energy rating?

Window energy ratings range from E to A++.

A++ is the best rating a window can receive, and anything rated C or above is considered good.

Is more heat lost through windows or walls?

An energy audit can help determine the cause of heat loss in your home. It may reveal that walls, rather than windows, are the main culprit.

Check your insulation type and R-value to see if it needs replacement or improvement.

Over the moon with the installation

A friend told me about the service from Plan-it and I give them a ring. They came on time and didn’t take ages, price was really really good and we are over the moon with installation as we was told 3 days and they was done in two. One of best buys I’ve ever made.
