Energy Efficient Windows

You may have heard about energy efficient windows, but do you know how they work? It’s all very well for you to want to have energy efficient windows in your home because so-and-so down the road has them. However, if you don’t know what good they can do, you can’t really justify changing them, can you?

Here you can learn how energy efficient windows actually work and why you should consider having them installed in your home.

How do energy efficient windows work?

Energy efficient windows are double or triple glazed windows. Whilst the term ‘energy efficient’ sounds way more eco-friendly, these windows all do the same job: prevent heat from escaping through them. You’re more likely to buy a window if you know that it’s energy efficient, right?

How do these windows save energy?

Double glazed windows have two sheets of glass (triple glazed have three, of course) with a gap in between. This gap creates an insulating barrier that keeps heat in, which in turn, helps improve the energy efficiency of your home, meaning you will spend less on heating bills.

These energy efficient windows are available in various frame materials and styles. Performance is affected by the following factors:

The ability to stop heat from passing through the window.
The amount of sunlight that travels through the glass.
How little air can leak in or out around the window.
Low emissivity (Low-e) glass is the most energy efficient material for double glazed windows. One of the internal panes has an invisible coating of metal oxide which lets in light whilst restricting the amount of heat that can get out.

Choosing the frame

There are different energy ratings for different frame materials. The type of frame you choose may be due to aesthetics, cost or energy ratings;

UPVC frames are durable and may be recycled.
Wooden frames can have a lower environmental impact but require maintenance.
Aluminium or steel frames are also long-lasting and may be recycled.
Composite frames need little maintenance as they have an inner timber frame covered with aluminium or plastic to keep the frame weatherproof.
The Benefits of Energy Efficient Windows

The costs and savings vary for each home depending on the size and material of each window, however, energy efficient windows last for many years and are the way forward in terms of window choice. Why? Take a look at the many benefits:

Benefts of energy efficient windows

Significantly reduced heating costs.
A smaller carbon footprint due to less fuel being used, therefore less carbon dioxide will be generated.
A more comfortable home because heat loss is reduced.
Peace and quiet. Energy efficient windows insulate your home against external noise.
Reduced condensation due to warmer interior glass surfaces.
