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.

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.

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.

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+.

Triple glazing is better at retaining heat inside the home, though it may not always be the best option. If your property is located facing north then triple glazing would make a great impact retaining the warmth inside your home. However, if you have a property facing south you could benefit from a low iron glass in a double glazed unit to harvest free energy from the sun.

Yes, if replacing single glazed with triple glazing then it does help to reduce noise pollution. If you are looking to reduce the amount of noise pollution entering your home, we would recommend looking at the type of glass used in your double or triple glazing. Acoustic glass has a special polymer layer between the panes of glass, which is specifically engineered to disrupt and absorb sound waves. As a result, less sound travels through the window.

Some homes are prone to the “greenhouse effect,” particularly in those that have south or west facing windows. Triple glazing may be a solution if you find rooms become unbearably hot. Having three panes of glass means that a triple glazed unit will not harvest as much solar heat gain as a double glazed unit making the room slightly cooler.

No. Standard double glazing units are 28mm thick. In comparison, a triple glazed unit, with three panes and two Argon filled gaps are normally 36mm. If you are looking to replace the glass from your double glazed unit with triple glazing it is advisable to speak to a professional.

If your property is particularly cold or susceptible to harsh weather conditions, then looking at installing triple glazing on uPVC windows could be the solution for you.

G-value or solar gain measures the amount of the sun's 'free' energy that the window lets into the property. Triple glazing, with 3 panes of glass, does reduce this solar gain. However, the fact that triple glazing will normally have two panes of Low-E glass means that the U-value is higher, resulting in a more energy efficient window overall.
