OUR MOST THERMAL EFFICIENT GLAZING.

Everest triple glazing is rated A++, the highest energy rating for windows and is endorsed by Energy Saving Trust. The extra pane of glass reduces the conductivity of the window, helping retain more heat in your home. This makes your home warmer, cosier and can help reduce heating bills too.

WHAT MAKES TRIPLE GLAZING ENERGY EFFICIENT?

It's not just the extra pane of glass that makes triple glazing energy-efficient. We add many more features to ensure its our most efficient window.

  • Low-E glass
    A microscopic metal coating reflects heat back into your home, making it warmer and cheaper to heat.
  • Storm sash
    Double rebated window with Q-Lon weather resistant seals for weather protection.
  • Argon gas between panes
    Heavier than air, it acts as an insulator, blocking out cold air for optimum insulation.
  • 5 chamber profile
    The sash profile is made up of 5 chambers, designed to prevent heat escaping.

IS TRIPLE GLAZING MORE SECURE?

The extra pane of glass not only helps with thermal efficiency, it can also make your home more secure. The extra pane of toughened glass makes the window more difficult to break and can even stop an attempt in the first place by acting as a deterrent.

All Everest triple glazed windows are also fitted with GrabLock as standard, and internal glazing bead, which prevents glass being removed from outside. So you can rest assured your home is safe and secure.

IS TRIPLE GLAZING WORTH IT?

Triple glazing is more thermally efficient and secure than double glazing, but whether it is the right choice for you and your home will depend on several factors.

  • +
    Is triple more expensive than double glazing?

    Yes, an identical triple glazed window will cost more than a double glazed window. However, this depends on a number of factors such as size and other window options chosen, but in general its between 10% and 20% extra.

  • +
    How energy efficient is the rest of my home?

    If your home is poorly insulated, triple glazing will have a less positive effect as heat will still escape from poorly insulated areas. If you have single glazing, then just upgrading to double glazing would make a huge difference.

  • +
    Is short or long term saving more important?

    If you want a lower initial investment then double glazing is the right choice for you. However, if you want to save more on your energy bills or energy-efficiency is important for you, triple glazing will be a better choice.

  • +
    Do triple glazed windows reduce noise?

    Many will claim it does just because of the third pane. This is incorrect as actually the middle pane can increase sound vibration and amplifying sound transference. If noise pollution is important for you we recommend you consider our Secondary Glazing or Acoustic Glass, which has been designed to be more efficient at blocking out noise, making it a great choice if you live on a main road.

  • +
    Do you live in a cold climate?

    The further North you live, the more suitable triple glazing would be. If you live in the south double glazing could be more than suitable, although you may want to consider triple glazing for North facing windows and double glazed for south facing.

  • +
    Does triple glazing reduce condensation?

    Condensation comes in three forms (on the outer pane, on the inner pane and between the panes) and it’s not always bad news. If it’s on the outside of the house this is good and a demonstration of quality windows. However, if it’s inside the house this is caused by a lack of ventilation and lower quality double glazing – increasing ventilation within the room can improve the issue otherwise new windows may be needed. If the condensation is in between the panes then your unit has failed and is letting in water, which will require a replacement to rectify. A window that has been designed to reduce condensation will have argon gas between the panes, a wide gap between the panes and a high energy rating of at least A+.
