FAQ

What is triple glazing?

Triple glazing, like the name suggests, is made from three panes of glass instead of double glazing, which only uses two.

Although your windows become thicker, they won’t look bulkier or ruin the aesthetics of your home. In fact, you’ll barely even notice the difference.

This type of glazing is popular in colder countries, because it offers more insulation for your home, and protects your home from the weather. As such, you can greatly reduce your heating bills and save more.

There is also a significant safety advantage, as triple glazed windows are harder to break. So while you reduce your energy costs, you simultaneously increase your home security.
You can find triple glazed windows in many different styles such as sash windows, bay windows, and casement windows.

How does triple glazing work?

Triple glazing works by placing three separate panes of glass within a frame which is often made from either uPVC, metal or wood.

These panes of glass have pockets of air in between, which is filled with a denser substance such as Argon. As such, it works as an insulator to reduce heat transfer, keep out noise and ensure your interior stays at the correct temperature.

What does this mean for you?

It means your home remains cool in summer and warm in winter. So you can save big on your energy bills.

Furthermore, triple glazing windows have various energy efficient ratings ranging from A++ to E. The higher the rating, the more energy efficient it is and the more money it saves you.
