If you want to maximise the thermal efficiency of your windows and home, triple glazing is the way to go. The extra pane of glass provides exceptional insulation, meaning that heat stays in your house for longer and you pay less for energy bills. Triple glazed windows also offer a number of other benefits, including reduced condensation and increased security.
The triple glazed window comprises of three panes of glass rather than two, and the space between each one is filled with inert gases such as argon or krypton. This reduces the transfer of heat, which helps to keep your house warm in winter and cool in summer. The outer panes of the window are usually made from low emissivity (low-E) glass with metal oxide coatings to minimise solar gain and to help keep your home cooler.
As a result of this the windows are super efficient, reducing energy bills and boosting the value of your home. They will also eliminate draughts, create a quieter living environment and help to maintain a consistent temperature throughout the house.
In addition, triple glazed windows are much more difficult to break than single or double glazed windows. This makes them a safe option for homes that are vulnerable to intruders as it would take a substantial amount of force to break through the glass.
Lastly, triple glazing is a great choice for those with allergies as the additional pane of glass will reduce the amount of moisture that forms on the windowpanes. Condensation is caused by warm air in the home coming into contact with cold windows and if left unchecked can lead to harmful mould growth. Triple glazing offers the best protection against this, with a lower dew point and superb thermal efficiency, moisture won’t be able to form on the inside of your window.
Unlike some other types of double glazed window, triple glazing does not have an inner frame between the three panes of glass. The gap between the panes is sealed with a warm edge spacer bar, which is designed to stop heat escaping around the edges of the window. The spacer bar is typically made from uPVC or another thermally optimised insulating material that doesn’t conduct heat and further insulates the window. In addition to this, all good triple glazed windows should be fitted with a high quality low-E coating and include argon gas fills between the glass for additional thermal performance. Having all of these features together gives the window a very low U-value, reducing heating and cooling costs.
