What are the advantages and disadvantages of triple glazing?

If you’re thinking about upgrading your windows and doors for your Lincolnshire, Nottinghamshire or South Yorkshire home, you’ve probably come across triple glazing. Triple glazed windows are becoming more popular due to their superior energy efficiency. But are they really worth it? Let’s break it down and answer the questions most homeowners ask.

What is triple glazing?

Triple glazing is exactly what it sounds like – three panes of glass instead of two. In between the panes are gaps filled with air or an insulating gas like argon, which helps keep the heat inside your home and the cold outside.

It’s the next step up from double glazing, giving you more insulation, less draught, and in some cases, better noise control.

Are triple glazed windows very expensive?

Yes, triple glazed windows are more expensive because they use more materials and have a more complex installation process. On the other hand, the initial extra cost may be offset by increased energy efficiency, improved comfort, and better noise reduction over time.

On average, you’ll pay about a third more than you would for double glazing. The exact price depends on factors like the size and type of the window, the frame material, and labour cost.

What are the main disadvantages of triple glazing?

Triple glazing isn’t perfect, and it’s not for everyone. Here are the downsides you should know about:

  • May be overkill: In milder parts of the UK, the energy savings are often small, so the extra cost isn’t always worth it.
  • Cost: It’s usually 30–50% more expensive than double glazing.
  • Weight: The extra glass makes windows heavier, which means you’ll need stronger frames and hinges.
  • Thickness: Not all window frames can handle triple glazing, so retrofitting isn’t always possible.
  • Noise reduction isn’t guaranteed: Triple glazing doesn’t always block noise better than double glazing. For serious soundproofing, acoustic glass can work better.

Does triple glazing increase house value?

Yes, triple glazing can increase house value. Buyers are increasingly looking for homes with good energy efficiency. Windows with an A or A+ energy rating are attractive, and triple glazing can help tick that box. It often also makes your home warmer, quieter, and more secure – all things that boost value.

According to the Federation of Master Builders, the investment may be well worth it:

Installing triple glazing can add value to your home by improving its energy efficiency, reducing heat loss, increasing security, and enhancing sound insulation. These benefits make your property more attractive to potential buyers, boosting its market value and appeal.

How hard is it to break triple glazed windows?

Triple glazing is much tougher to break than double glazing because of the extra pane. It gives burglars more of a challenge. If you really want maximum security, you can go one step further and choose laminated glass, which stays in place even if it cracks.
