Triple Glazing

Many people in the UK are familiar with double glazing. Double glazing is now present in many homes and provides good sound proofing and insulation; it also gives the home a modern and stylish look. What many aren’t familiar with is triple glazing; cold weather climate countries such as Canada and Norway have long been using this form of window. Having triple glazed windows in your home can provide even more benefits than double glazing, whilst never losing the modern look and low maintenance appeal.


Windows are an important part of every house and business as they let in light and provide protection from weather elements; windows are also one of the most exposed parts of the building. The aim of windows apart from the obvious means of being able to view the outside world and allow natural light to homes is to provide:

  • Insulation against heat loss
  • Reduce noise from outside
  • Protection against moisture and rain
  • Resist extreme temperature changes

Safety is also a big part of modern windows, they must be able to create an environment that is safe for children and adults alike, and as a consequence many windows in today’s world have locks and safety catches.

What is triple glazing?

Triple glazing, although not as widely used as double glazing at the moment, is becoming more and more popular. Over the next few years it is likely that all new houses will move from double to triple glazing and UK building regulations are expected to make triple glazed windows compulsory.
The basic element of triple glazing is that the window will contain three layers of glass separated by an air gap. The air gap will provide insulating layers that reduce heat loss and prevent condensation from forming, and the glass is also sealed to provide noise reduction.  Experts have discovered that every saved kilowatt hour reduces carbon dioxide emissions by one kilo; triple glazed windows can help towards this and in the process save the owner hundreds of pounds in electricity. Although more expensive than double glazing the all-round benefits make them a sound investment especially when combined with insulated exterior walls giving the house unparalleled energy efficiency.
In the early days of production triple glazed windows were basically the same as double with an extra layer of glass; this led to frames becoming bulky and too deep to be fitted in conjunction with wall thickness.  Recent advances in the way they are designed and produced have led to a better, more stream line product that can be accommodated to most households.
Heat loss not only occurs through the glass panels but also the frame; this has been combated through installing triple glazed windows using low conductivity materials such as:

  • Softwood
  • Hardwood
  • PVC
  • Glass fibre and composites

The hollow design of the frame can aid in heat reduction and provide comfort to owners. Most houses will have triple glazing installed with a PVC frame; this not only gives a good finish but also is easy to clean and maintain.
