It is a fact that adding a triple glazed unit to a window improves the energy efficiency and sound proofing of a window, to a point where triple glazing could increase the performance of a window by approximately 50% as compared to standard energy rated double glazing.
Simply put, minimum regulation requirement in the UK states that all windows now installed must be at least C rated, C Rated windows must have a maximum whole window U-value of 1.6W/m2K. The best available on the market in double glazed windows is an A Rated window; this must achieve a maximum whole window U-value of at least 1.4W/m2K.
Triple glazing is another evolutionary step in glass; it is believed that the earliest manufacture of glass known to date was around 3500 BC in Mesopotamia. Glass is thought to have been developed in the late Roman Empire at the roman glass making center in ‘Trier’ which is now modern Germany.
Since the old days, glass has been developed to become stronger (float glass) and more versatile to suit many uses. Glass is becoming a more popular building material due to its durability, energy efficiency, sound proofing and quick manufacture.
The ‘window sector’ saw one of the largest booms in its history during the early 90’s all the way through to the turn of the millennium as people rushed from single glazing to double glazing. People could see and feel the difference the ‘extra pane’ of glass made to their old single glazed windows.
Some triple glazing critics claim triple glazing is not as energy efficient because solar gain is reduced due to the additional pane of glass; this is true to some extent but using an extra clear pane of glass for the center pane can keep this loss to a minimum while at the same time increasing performance dramatically.
As energy costs spiral out of control choosing the most energy efficient windows and doors has never been more important. Energy efficiency is one of the most important aspects of everyday life from cookers to kettles, cars to Eco homes. We all ‘stop and think’ before we buy as to how much will it cost? Is it energy rated and how much can I save?
Triple glazing can be better in performance to conventional rated double glazing by approximately 50% making it the wise choice if you are looking to replace your windows and doors.
