Triple Glazed Windows

Our A+ rated triple glazed windows are the perfect choice for a warm and energy-efficient home. The third pane of glass improves heat retention, helping to save on your energy bills.

Triple glazing is ideal for north-facing windows or those where there isn’t much natural sunlight. Here, it provides the best insulation properties compared to double glazing. They also provide increased noise reduction for rooms facing busy roads, helping to make your home quieter and more comfortable.

Triple glazing features three panes of glass with the spaces between the panes filled with an insulating inert gas, usually argon. This means triple glazed windows provide an extra level of insulation over double glazing. Because it is so good at heat retention, triple glazing doesn’t suit rooms that get a lot of sun, especially in the summer. Mix and match your windows to suit the aspect and elevation of your home and windows.

Reasons to Choose Triple Glazed Windows

  1. Increase Energy Efficiency

    Our triple glazing has an energy rating of up to A++ with uPVC flush windows, helping reduce heat loss. This means that with triple glazed windows, you use less energy heating your home, lowering your bills.

  2. Add Value to Your Home

    New windows, particularly triple glazing, can help add value to your home by improving how it looks and its energy efficiency. Triple glazing can help increase your Energy Performance Certificate score, which can boost its appeal to buyers.

  3. Decrease Outside Noise

    Three panes of glass and inert gas in between make it much harder for sound to enter your home through triple glazed windows. This makes them perfect for city properties and rooms that face busy roads.

  4. Enjoy a Warmer Home

    Triple glazing stops warmth escaping your room, while also keeping out the cold. This makes them a great choice for colder, north-facing rooms that don’t get much sunlight.

  5. Reduces Condensation

    The extra insulation in triple glazing means a warmer inner glass pane. This lowers the chances of condensation forming on windows when humid air meets cold glass.

Triple Glazing vs Double Glazing

Modern triple and double glazing are both good choices for your home, but which is better?

Triple glazing is better than double for colder rooms because it retains more heat and blocks more cold air. However, double glazing works better in rooms that get a lot of sunlight, because triple glazing locks in more heat, making warm rooms too hot in summer.

That’s why we recommend mixing and matching double and triple glazed windows throughout your home, to keep it as comfortable as possible all year. Find out more about choosing double or triple glazing in our handy guide.

Your Questions Answered by Us

Is triple glazing good in summer?

Triple glazed windows are good in summer, but it depends where they are in the home. Triple glazing lets in less of the sun’s heat, retains more warmth and reflects it back into your room more than double glazing. So installing it in rooms that get a lot of sunlight would make them hotter than if you had double glazing, even though they let in less of the sun’s heat.

Do you get condensation with triple glazing?

You can still get condensation with triple glazing, but they are better at reducing it compared to double glazing. The extra insulation and thermal efficiency of triple glazing keeps the pane of glass inside your room warmer, reducing the chance of condensation forming.

Does triple glazing cost more than double glazing?
On average, triple glazed windows cost about a third more than double. This is due to the extra materials required to make triple glazing. That said, triple glazed windows have higher energy efficiency ratings than double glazed, further reducing heat loss. This in turn reduces the amount of energy you use heating a room. The saving makes the higher cost of triple glazed windows more cost-effective in the long run.
Is triple glazing worth it?

Triple glazing is worth considering for persistently cold rooms and spaces in your home. Triple glazing provides the best insulation, helping to retain warmth and help reduce your energy bills in winter.

Triple glazing makes the most difference in north-facing rooms or any part of your home that’s persistently cold. Triple glazing can also add value to your property, helping increase its EPC rating.

Does triple glazing make a room warmer?

Yes, triple glazing will help keep a room warmer thanks to its superior insulating properties. It’s ideal for rooms that tend to stay cold because they don’t get any sun, helping to keep them at a more comfortable temperature through the winter.
