Triple glazing is when your home benefits from three panes of glass rather than one or two window panes. This extra pain increases energy efficiency and reduces the amount of outside noise that makes it into your home.
These benefits are particularly apparent when you upgrade from single glazing to triple glazing. The jump in benefits when you upgrade from double glazing to triple glazing is less significant, but it’s usually worth the extra expense, particularly if your double glazing windows are due for renewal due to aging and wear.
The benefits of triple glazing
The energy efficiency of a window is measured by the U-Value. The lower the U-Value, the better. Single glazed windows have a U-Value of 5. Double glazing has a U-Value of around 1-3, depending on the age of the double glazing. Triple glazing has a U-Value or 0. This actually beats the U-Value of walls. Your walls have a U-Value of around 0.3. This means the ‘payback period’ for triple glazing is generally much quicker than that obtained from single or double glazing.
