Double Glazing and Its Advantages

Double glazing has two panes of glass that are separated by a thin layer of air. In fact, double glazing comes with many advantages compared to single glazing windows which have only one pane of glass with no air layer. Here are some of the advantages:

  • It retains warm air inside the house during winter. That means your house is insulated – which helps reduce your energy bills over time.
  • Keeps the noise out. You won’t hear loud noises from outside with double glazed windows and doors.
  • It reduces the amount of condensation inside of the windows.
  • Extra security because double glazed windows are more difficult to break.

How Much Can I Save If I Install Double Glazing?

More than 60% of the homeowners surveyed said that their homes were much warmer since they installed double glazing. More than 36% of these homeowners said that they saw a reduction in their energy bills over time.

If you own a three-bedroom semi-detached home and decide to replace all of the single glazed windows in the house, you can save between £75 and £100 per annum as per the Energy Saving Trust – with a B-rated glass. If you use an A-rated glass, the savings increase to £85-£110 per year. Double glazing frames last for more than 20 years. Hence, you can easily save between £1,500 and £2,200 for 20 years.

The Types of Double Glazed Frames

uPVC is the most common type of double glazed frame on the market today. In fact, unplasticized polyvinyl chloride or uPVC is three times cheaper compared to traditional wooden frames and recyclable at the same time. It is considered the best energy-saving frame on the market today.

uPVC frames come in a wide variety of colours, sizes, and finishes. White is a popular option for many customers. You only need to wipe the frames with a soft cloth to maintain it. Make sure to use a washing liquid every now and then.

Wood and aluminium frames are alternatives to uPVC frames. In fact, timber is a naturally renewable and greener option compared to uPVC. Many homeowners feel wooden frames look subtle and nicer compared to uPVC, especially in period-style or traditional properties. Although timber window frames are more expensive and require maintenance, they can last a long time when cared for.

Window Energy Rating (WER) System?

This rating system is quite similar to appliance rating systems. Widows are rated A+ for the best and G for the worst. Building regulations in the country need all window frames to be at least C-rated. Each manufacturer has different levels of ratings such as A++.

As per our calculations, you should get B-rated windows to save an additional 6.5% on your energy bills. That is why you need to consider the rating of the window frame when purchasing it.
