Triple Glazing

  • If you want to upgrade to an even more energy-efficient window, then opt for triple glazing.

    Triple glazing works in much the same way as double glazing. Frames are built with gaps between the glass, where a gas is used to reduce heat transfer and stop cold air from coming inside. But when it comes to triple glazing, there’s an extra pane of glass and an extra layer of this gas, so heat retention is enhanced, and you’ll stay cosy even on the coldest days. These are the most energy-efficient windows on the market. 

    St. Ives Windows create some of the most innovative window products, and that includes our triple glazing range. They help keep your home cosy, so you spend less on your energy bills.

    You’ll often find triple glazing in some of the coldest countries of the world. In Scandinavia, it’s often used to make homes energy efficient, and it also helps reduce the amount of outside noise that enters your home.

Common Questions

Can triple glazing make a difference?

Triple glazing is much more insulative than single- or double-glazed windows or doors. When measuring the insulative properties of glazing, we use the U-value. The lower the U-value, the lower the heat loss. The U-value of double glazing is 1.2 on average, while triple glazing is only 0.6, meaning they are around twice as efficient. On cold days, when you turn on the heating, very little heat escapes from triple glazing, so you can cut your energy bills.

Is it worth upgrading from double to triple glazing?

Triple glazing has excellent insulative properties, which is why you’ll often see it used in Scandinavia, where winters can be long, bitter and extremely cold. If you live in a rural or coastal area of Cornwall, where the nights can be particularly chilly, it may be worth upgrading to triple glazing. However, if you live in a town or city, and already have decent double glazing, you might not notice a huge difference. Why not speak to us about whether triple glazing is suitable for you?

How long can triple glazing last?

When you buy triple glazing from St. Ives Windows, you get a 10-year manufacturer’s guarantee. However, they’ll usually last much longer for that. We’d usually expect them to offer good energy efficiency for 20 years, and sometimes up to 35 years with only a slight reduction in insulative properties. You can help your windows last longer by giving them a clean with warm, soapy water on a regular basis to remove dirt and debris.

What is the difference between double and triple glazing?

Double glazing is made with two layers of glass in the same pane, with a gap in between that’s filled with a dense gas called Argon. This dense gas allows for better insulation, as it stops cold from the outside transferring to the inside pane, and also helps dampen outside noise. Triple glazing works in a similar way, except with an extra panel, allowing for even better insulation and noise dampening. Of course, this does result in a slightly thicker pane, so it’s worth thinking about whether you’d prefer a slimmer frame or better insulation.

We refuse to compromise on quality

They are built specifically for the more exposed areas of corrosion, such as coastal environments to give you worry free performance beyond your guarantee.  We believe spending more on components is worth every penny, and sets us apart from our competitors.

We have invested millions of pounds into one of the most state of the art manufacturing facilities in the UK.  This enables us to provide you with consistently high quality products at exceptionally good prices. Our loyal factory workers are well trained and take pride in their work, they really care about quality.  Our machines are maintained according to a rigorous servicing regime to keep them in top condition.

Superior energy efficiency

Our ‘A’ rated energy efficient and triple glazed windows are tested by the BFRC, which will save you money on your heating bills. By law your windows and doors have to meet strict thermal performance regulations but you can be rest assured that our products exceed current requirements.

Energy saving is incredibly important and so is keeping your fuel bills down. We are continuously looking for ways to make our projects energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your project warmer, they will reduce your energy loss.

Don’t just take our word for it!

Our suppliers conform to strictly controlled and independently monitored Quality Management Systems such as ISO 9001, to ensure that everything is done correctly and according to best practise.

Our windows are tested independently by British Standards for security, weather tightness and strength performance. This means that periodically, we have to send them to independent test houses, in order to be tested to destruction.

These are just some of the many standards the products in our vast range conform to. Needless to say we take the quality of our products very seriously indeed.
