Yes, an identical triple glazed window will cost more than a double glazed window. However, the overall cost of window is dependent on more than just the glazing option such as size and number of openings required. In general its about 10% to 20% extra but our experts can help you to select the right options to bring this into your budget range.

Many will claim it does just because of the third pane. This is incorrect as actually the middle pane can increase sound vibration and amplify 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.

Yes they should is the short answer but 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 would be advised. 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.

Both offer benefits and advantages. Triple glazing does offer better thermal efficiency ratings and is better at retaining heat inside the home, but it is more expensive versus double glazing. Also you need to consider if you need it for example if your property faces north then triple glazing would make a noticeable difference. However, if you have a property facing south double glazing will probably suffice.

Some homes are prone to the "greenhouse effect," particularly in those that have south or west facing windows. Technically this issue is called solar gain and is measured by the G-value or solar gain which measures the amount of the sun's 'free' energy that the window lets into the property. Triple glazing, with 3 panes of glass has a lower G value and will result in lower solar gain compared to double glazing.
