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.

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.

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.

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.

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.

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+.
