What is Triple Glazing?
Triple-glazed windows have three panes of glass, one more than double-glazed. The space between the glass is filled with an extra layer of insulating inert gas, like argon. Together with the third pane of glass, triple glazing often has a higher energy rating than double glazing. It helps to keep your home warmer, quieter and safer.

Reasons to Choose Triple Glazed Windows
Increase Energy Efficiency
Our triple glazing is A+ rated as standard, but can reach up to A++ with uPVC flush windows. Increased efficiency means you use less energy to heat your home, lowering your bills.
Add Value to Your Home
Triple glazing improves overall energy efficiency of your home, increasing your Energy Performance Certificate score. Getting a higher rating will add value to your home.
Decrease Outside Noise
The three glass panes reduce external noise penetrating your windows. Perfect for city homes and those on main roads.
Enjoy a Warmer Home
Triple glazing stops warmth escaping your room, while at the same time keeping the cold out. This makes them perfect for colder rooms that don’t get much sunlight.
The extra insulation in triple glazing means a warmer inner glass pane. This lowers the chances of condensation forming when humid air meets cold glass.
