Upgrading to triple glazing windows from double glazed units means that you get three panes of glass with the middle pane allowing two spaces of air or a heavy gas such as argon on either side. The whole glassware is hermetically sealed by approved glaziers as one vessel and can be assembled with 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm or 20mm spacer bars. The benefits include a more custom size for your needs, better soundproofing and extra thermal efficiency with optional low-e glass.
Triple glazed windows are designed to reduce heat transfer and can maintain the inside temperature higher than other airtight glazing units. This is important as it eliminates condensation inside the layers by keeping the temperature above the 5°C dew point where the misty glass effect typically occur when the cold surface is hit by the moisture in the air.
