Triple Glazing

What is Triple Glazing?

Triple glazed windows are a high-performance glazing option

Triple glazing features 3 panes of glass rather than 2 like double glazing. Sitting between these panes of glass are two cavities that are filled with Argon, which is an inert gas. Inert gases conduct heat very poorly, so this provides modern improvement to the insulation qualities of triple glazing.

Triple glazing benefits:

  • The best levels of energy efficiency ratings on the market
  • Can be fitted to the majority of our window styles
  • Perfect for anyone living on a busy road or under a flight path
  • Keeps your home at a comfortable temperature all year round
  • Save money on your heating bills and reduce your carbon footprint
  • The extra pane of glass adds durability, securing your home
  • Adds more value to your home than standard double glazing

Benefits of our Triple Glazing for Surrey Homes


Energy Efficiency

By using three panes of glass and two Argon-filled cavities, triple glazing blocks heat from escaping thanks to lower U-values and higher energy ratings. So, you can remove any cold spots in your rooms and create a cosy living environment with significantly lower heating bills. Even better, they’ll improve your home’s environmental footprint.


Reduce Condensation

As wall insulation has improved, there is a bigger disparity between the insulation provided by the windows and the rest of the home. This leads to a build-up of condensation on the windows. However, as the most insulating glazing solution, there is less disparity when triple glazing is fitted, meaning condensation is minimised.


Heighten Security

3 panes of glass are harder to smash than 2, so triple glazing provides your home with another layer of security, making it harder to break into. When you consider our triple glazed windows also come with a range of excellent locking hardware, you can be 100% certain that your home will have expert protection in place.

Energy-efficient triple glazing will reduce your carbon emissions

Although triple glazing is more expensive to fit than double and secondary glazing, this is because of the superior performances that it offers that no other glazing option can compete with. Triple glazed windows truly are the pinnacle of glazing solutions. As it is the most energy-efficient glazing choice of the three, it offers the highest potential savings on energy costs.

By reducing energy costs and the amount of energy your property consumes, fewer fossil fuels are required so the number of carbon emissions is lower as a consequence. This makes replacement triple glazed windows perfect for anyone who wants to do their bit to help the environment.

Technical Information


Energy Ratings

Triple glazed windows are capable of achieving the highest possible Window Energy Ratings. Window Energy Ratings run from E to A++ with E being the lowest and A++ the highest. The best triple glazing can attain ratings of A++, providing you with an energy performance that is truly outstanding.


Noise Reduction

With so many layers to get through, the strength of soundwaves making their way into the home is dramatically reduced. Some of the best double glazing can keep 35 decibels from entering your home, but triple glazing can keep out even more than this, making it perfect if you reside in a noisy area.


10-year Guarantee

If we fit your home with a triple glazed window, it comes with a 10-year insurance backed guarantee. This means that you’ll have comprehensive cover in place for 10 years even if we happen to cease trading for whatever reason.
