What is Triple Glazing

What is triple glazing? This is a popular question and one that is being asked more frequently now that more companies are offering it alongside their traditional double glazing services. Triple glazing was once only used in colder weather climates and on grand design houses that use the most modern features; it is now becoming popular with many people across the UK thanks to the benefits that it offers.

What does it comprise of?

The first step in answering “what is triple glazing?” is to look at what triple glazing comprises of. It has many similarities to double glazing in the way that it is designed; double glazing features two panes of glass which are separated by an air gap. The air gap provides an insulating layer which slows down heat loss and reduces the chance for condensation to form. Triple glazing features an extra pane of glass and an extra air gap and this further increases heat reduction capability as well as providing noise reduction. The air gap is crucial to the performance of the window - if the gap is too small between the panes the result is less radiant heat loss. Too wide then difference in temperatures and heat transfer can occur between the panes.

The air gap between the panes can be treated to increase energy efficiency. Although the air gap itself is often sufficient, filling with an inert gas such as argon can improve thermal performance. The gas may not last as long as the window it is in and can easily leak with a flaw in the seal, but this has led to seals being improved to comply with the high standards of the window.

Benefits

Another popular question to “what is triple glazing?” is “what are the benefits?” People will be reluctant to buy triple glazing if the negatives outweigh the positives. Also many people with double glazing may not see the need to upgrade.

There are two main benefits to specify when asking “what is triple glazing?” The first is thermal performance. Triple glazing is designed to reduce heat escaping from the home in cold weather and provide protection from solar rays and reduce heat in warmer months. Around a third of all heat lost from a house is through poorly insulated windows; heat can easily escape through the glass and frame of a window this can add between 15% and 33% on yearly heating bills. Triple glazing with its extra glass panes and air gaps as well as low conductivity material frames can significantly reduce heat loss and therefore keep costs low. It also reduces carbon emissions which is the overall aim trying to be achieved by the government.

The other main benefit is the reduced noise reduction that triple glazing can provide, for those that live close to busy roads and areas’, reducing the outside noise is important for a quiet and comfortable life. The construction of triple glazing means that it is able to block out outside noise.
