What is triple glazing?

In construction, triple glazing is a term used for windows and glass doors that have 3 panes of glass. Primarily this means that a single piece of glass is reinforced with two layers, or “lites” of glass. Triple glazing creates a much stronger and more energy efficient window than double glazing. The extra layer of glass ensures your home is warmer in the winter months and cooler in the summer months.

In Brighton, Trade Timber Windows and Doors is certified to install triple glazing units. Triple glazed windows and doors offer an effective alternative to double glazed units because they keep outside noise, draughts and condensation out while providing excellent insulating properties.

Double Vs Triple Glazing

A lot of our customers ask which is better for their home, double glazing or triple glazing. Under certain conditions double-glazed sashes may not perform well enough to be classed as super energy efficient, making triple glazing an optimal solution.

Triple-glazed sash windows are the preferred option as it consists of three separate panes of glass, instead of two pairs, sandwiched together with a spacer. Triple glazing provides greater thermal protection against cold and draughts. This significantly reduces heat loss and noise transfer, bringing increased insulation, security, and comfort. If you’re looking to maximise the energy efficiency in your home, upgrading to a triple pane window is a great way to go.

Triple-glazed windows offer better insulation and energy performance than double glazed alternatives, while single pane windows tend not to insulate effectively at all.

Triple glazing also improves your home’s security by reducing vibration and providing good soundproofing.

While you can choose double-glazed windows over single-glazed windows for your home, triple glazing offers you even better soundproofing and reduced heat loss.
