What Are Double Glazed Windows?

Double glazed windows are installed in the large majority of properties in the UK. They are made up of two panes of glass with gas in between them. This provides a layer of insulation and soundproofing – and they are more secure than older windows, keeping your home and family safe.

The gas between the two sheets of glass in your double glazed window is usually Argon, Krypton or Xenon, but in some cases a vacuum is used instead. Your installer will tell you the best options for your home.

Benefits of Double Glazed Windows

There are a lot of benefits to double glazed windows, and most newer houses are built with it installed as standard. For older houses, upgrading to double glazing is a worthwhile investment because they:

Are more secure
Lower energy bills by keeping more heat inside
Reduce draughts, making it more comfortable for occupants
Have less condensation on the inside
Reduce noise levels from outside
Add value to your home

You can replace your existing single glass with double glazed windows within your existing wooden window frames, but this won’t be as efficient as more modern and specifically fitted frames. You should check to see how draughty your windows are around the frames and whether this will make a difference.

What To Look Out For In A New Double Glazed Window

Your new double glazed windows should not only keep you safe, warm and secure, but they should also be aesthetically pleasing and complement the style of your property. This adds more factors for you to consider when looking to upgrade or install new double glazing windows.

The best double glazed windows should:

Be visually pleasing
