Triple glazed windows are among the most energy efficient available on the market! There are many options available to create a triple glazing effect from PVC-U profile, including Planitherm Total+ glass, Argon gas filled sealed units, composite spacer bars and thermal reinforcing. All of these options can team up from a variety of manufacturers to deliver thermal U-values that cannot be beaten by traditional double glass pane arrangements. Why is three better? Triple glazed windows offer the maximum performance available in terms of thermal efficiency. The three panes significantly reduce the heat loss that can escape through to the outer pane. By filling the pane recess with Argon gas, the heat loss is reduced through each pane as heat does not transfer well through the gas.
