Triple Glazing....

Put simply, triple glazing is 3 panes of glass instead of 1 or 2. The claim is that by having an extra pane, you will increase efficiency and reduce noise. We already know that double-glazing makes a significant improvement over single glazing, but even so upgrading from single to double-glazing takes a long time to payback in terms of energy efficiency. So would making the jump to triple glazing make that much of a difference?

As you may be aware, the energy efficiency of windows is measured with a ‘u value’ and the lower this value the better.

Single Glazing has a U value of 5, older double-glazing about 3 and new modern double glazing a u value of 1.6, which is mainly due to improved methods of double glazing compared to older models. These improvements have been made through optimisation of the window cavity, the use of low emissivity coatings, using inert gas to fill the gap, and using aluminium spacers or ‘cold bridges’.

All this has brought down the u value of modern windows considerably, so does that make triple glazing worth it, if double glazing is now so much better? Well, walls have a u value of around 0.3, so it is clear that windows have a long way to go before they are no longer a weak point in the efficiency of the building.

Triple glazing offers a significant reduction in noise pollution – so it is ideal for those living in noisy areas.

Lots of new homes are now being built with triple glazing and it is generally acknowledged as being better, but compared to top double glazing, the payback period is very similar. As we have mentioned elsewhere, on a purely efficiency basis, double-glazing does not pay for itself and triple glazing is no exception. Changing from Single glazing to triple glazing, in terms of energy efficiency payback, is very similar to double-glazing payback.

1. Save even more on your energy bills - triple glazed units have an optimised
energy balance to maximise cost savings. Triple glazing allows a high level of solar heat gain, capturing free heat energy from outside during the daytime to warm the home. This is combined with exceptional thermal insulation properties with triple glazed units having a very low U-value* to keep the heat in during night and day. The outcome is a window that well exceeds the current maximum "A" window energy rating.

2. Maximum comfort - the thermal efficiency of triple glazed units ensures that cold spots are eliminated. Triple glazed units can also be optimised to deliver excellent thermal acoustic performance - minimising noise levels from outside.

3. Enhanced security - the extra pane of glass ensures that your windows are less easy to break through giving you peace of mind when it comes to security. Triple glazing is well established in many parts of Europe and is becoming increasingly popular in the UK. Windows are one of the most exposed parts of a house. According to the Energy Saving Trust, a staggering 26% of all domestic heat loss escapes through the windows. Installing energy-efficient windows is essential to help keep the cost of energy bills down.
