What Is Double Glazing?

Double glazing is exactly what it sounds like. While most windows consist of only one sheet of glass, double-glazed glass consists of two sheets of glass with a dry air gap between the sheets.

How Does It Work?

Since double-glazed glass consists of two sheets of glass with dry air between the sheets, the glass is stronger and better insulated. This works because the air gap between the glass sheets is a poor heat conductor. As a result, the heat inside your home stays inside and the cold air stays outside. In the warmer months, your home will remain cool as well, as the same science applies.


  • Reduced Heating and Cooling Costs: Since there is less heat transfer, you can look forward to lower heating and cooling costs inside your home.
  • Improved Durability: Since the glass has two layers, you can depend on your windows and doors being more durable. This helps to discourage break-ins and provides extra support during storms.
  • Long Lasting: While all windows require replacement over time, double-glazed windows and doors are known to hold up for much longer, so you won’t need to replace them as often.
