Triple glazing is still a relatively new concept in the UK. But in colder countries like Scandinavia, where homes endure extreme winter weather, they have been a used for many years. Whilst the UK might not get the same severity of weather conditions, it does still suffer from harsh winters . There are many other ways to insulate your home like the roof, walls and floor, but neglecting your windows can result in cold spots and condensation.
I installed 44mm triple glazing into my own home in 2012 and I have enjoyed the benefits ever since. Some from within KJM would describe me as "Triple glazing Guru", as I passionately believe in the product. I was even asked to speak at a national trade show about the triple glazing benefits, but declined as it was over three days and in Telford, along way from our base in Hampshire. There are pro's and cons's to triple glazing and I will do my best to explains this in simple terms.
Building regulations have become more stringent regarding thermally efficiency. The method of comparing the energy performance of windows is to use the U-Value, as used when comparing other parts of your home like walls, roofs and floors. History has shown U-values in windows have dropped. Back in the days of single glazing, windows had a U-value in excess of 5, early double glazing from the 70's/80's reduced this figure to 3, but over the years the u-value on the best double glazed units has dropped to around 1.0, with the introduction of warm edge spacers, argon gas and low-e glass. 44mm triple glazing offers a centre pane U-value of around 0.62. This type of window offers over 40% better insulation than "A" rated double glazing. It is in most cases over 25% better insulated when compared to 36mm triple glazing. You can use 28mm triple glazed units (2 x 8mm gaps) filled with krypton gas and 3 layers of 4mm glass which achieves a centre pane u-value of 0.66. The offer of this smaller unit because some windows cannot accept the wider 44mm units and some of our customers prefer the bead detail on the 28mm system. Krypton gas works better on smaller air-gaps than argon, but is MUCH more expensive than argon filled units.
