What exactly is triple glazing?

Triple glazed windows are almost twice as expensive as double glazed windows, for good reason. These windows have an extra pane of glass and an extra inner compartment filled with insulating gas which further increases the energy efficiency of your windows. The extra pane of glass can make these windows too heavy for certain walls though, and you generally cannot get wooden frames for triple glazed windows due to their weight.

The extra layer of separation from the outside results in a higher level of insulation from cold, heat, sound and intruders. To find more about the benefits of installing triple glazing in your home, see below.

How will I benefit from triple glazing?

There are many benefits to triple glazing windows which we will outline for you here:

  • It keeps you warmer

Triple glazed windows are noticeably better at insulating rooms than their double glazed counterparts. With a whole extra pane of window glass and insulating layer, you will be very warm inside a home with triple glazing throughout – though you should ensure your frames and walls are as insulated as your windows to minimise energy loss!

  • It reduces condensation

Have you ever woken up to beady drips of water on your window? Same here. It is not fun mopping up windowsills first thing in the morning, and triple glazing almost completely eliminates condensation problems—a true revelation for seasoned window-moppers.

  • It saves you money

Unless your windows are really old or only single glazed, double glazed windows are more than enough compared to triple glazing. In the case of replacing old windows, the extra cost of triple glazing windows will certainly save you money on your energy bills. This is because you will be conserving more heat inside your home.

  • It keeps your family safe

That extra pane of glass makes triple glazed windows a lot more difficult to break. Because of this, intruders will have a harder time breaking into your home. Panes can be reinforced for especially at-risk windows, but triple glazing is already much safer than double glazing.

  • It reduces noise

While the sound of children laughing and playing can be a gift to our ears, sometimes you just want a bit of peace and quiet. Triple glazing could revolutionise your weekend relaxation times by providing extra sound insulation so that those lovely little ones can scream away without disruption.

Should I choose double or triple glazing?

With such a steep price in comparison to double glazed windows, why should you choose triple glazed windows? Here are some factors to take into consideration when thinking about installing triple glazing:

  • How old are your windows?

If your windows are single glazed or are pre-2000 double glazed, they would most likely benefit from being replaced by triple glazed windows. If you have recent double glazed windows, you will not benefit as much from replacing these with triple glazing.

  • How well insulated is your home?

There is no point in having super-insulating windows if you have other non-insulated areas in your home. Make sure that your home is well-insulated before considering triple glazing, and the benefits you reap will be even greater.

  • How sturdy are your walls?

Triple glazed windows are more than a third heavier than double glazed windows. Ask your window installer if your walls will be able to hold the extra insulation before anything else. You may need reinforcement if your walls are older and weaker.

  • What matters most to you?

At the end of the day, you must make the best decision for you and your home. Do you want extra protection in certain areas? Do some rooms need extra insulation from noise or cold? Talk your window provider through the needs specific to each room that needs new windows. This way you will make sure you get a good fit for each unit.
