Everything you need to know about double glazing

When people buy an older house one of the first home improvements they look at doing is replacing the windows. Old wooden frames can be draughty and look unsightly if they haven’t been well maintained.

By installing modern, energy-efficient windows you could save as much as £100 a year on the energy costs of heating an average home – http://www.energysavingtrust.org.uk/home-energy-efficiency/energy-efficient-windows. This is because the latest double glazing is much more efficient and the frames are better sealed, so even if you have older double glazing already it could be worth your while upgrading.

Glass matters

Double glazing is made up of two panes of glass with an air gap between them, although in modern glazing you will often find suppliers offering three layers of glass. The gap between the panes is usually filled with an inert gas that makes it harder for heat to escape. On modern sealed units the gap between panes is also wider than that typically found in older windows, making them more effective.

When you buy new windows Dublin based suppliers will usually specify glass that has a low emissivity coating. This helps reflect heat back into the room and it also helps to retain heat gained from the sun, so you will spend less on heating.


If you are improving your home in Dublin windows are going to be a key feature. You can fit double glazed units in many types of frames. Your choice will usually be influenced by the style and age of your property.

The most common solution is to opt for UPVC frames. These are made from a rigid PVC profile that is welded at the corners to form secure joints. UPVC is strong and light and it is resistant to heat, cold and sunlight, so it’s a great choice for windows, making them largely maintenance free, just needing a wipe down to keep them looking smart. They can be made in many styles from modern to traditional sash, so will suit a wide variety of homes.

The latest frames have good seals on the opening parts of the frame, helping to retain heat and cut draughts, but also reducing the amount of noise that comes in from the outside. They will also have locking handles built in so will make your home more secure.
