Single glazed windows were the only available option for householders looking to replace their existing windows prior to the development of double glazing and nowadays double glazing has a rival of its own – triple glazing.
Triple glazing was originally very hard to get hold of in the UK as it was more typically used in extremely cold countries like those in Scandinavia, but most window suppliers, including ourselves, now stock the product having incorporated it into our respective ranges a few years ago.
This has left many window buyers questioning whether they’re best to get double glazing or triple glazing fitted at their home when new windows are a must.
It is a difficult decision and one that should only be made after you have assessed how both perform in several key areas.
The U-value of a window symbolises the standard of insulation provided by the design. If you want the highest level of energy efficiency you need to invest in a window with the lowest possible U-value.
The average U-value of a UPVC triple glazed window is only 1.0 W/m²k. This impressively low figure makes a UPVC triple glazed window 40% more thermally efficient than a normal “A” rated double glazed window and 60% more thermally efficient than a normal “C” rated double glazed window.
Many window companies claim that triple glazing is hugely effective at keeping noise out of the home, ideal for anyone who lives in a house hampered by noise caused by traffic on a busy road or passing trains or planes.
This isn’t entirely true as it would only provide exceptional noise insulation if the three panes included were of different thicknesses as sound passes through a solid more easily than through air.
A standard triple glazed window has glazed panes and cavities of the same thickness and it would also need to be sealed correctly to offer the type of noise reduction that some advertise.
Like so many things in life, when buying anything new, cost is a big consideration. There isn’t much difference in cost between a double glazed window and triple glazed window.
When upgrading from single glazed windows you should also bear in mind that the energy savings you make will be significant and should cover the initial cost of the windows.
You should have immense confidence that your windows will effectively protect your home whenever you leave it empty or head up to bed at night.
Double glazed and triple glazed windows boast a very durable window frame and have ready incorporated multi-point locking mechanisms.
The ultra-security conscious homeowner may be more drawn towards triple glazing as it has that added pane of glass and provides an extra obstacle for thieves to overcome.
