Triple-glazed windows have three layers of glass, or two layers with a low-emissivity (Low-E) film suspended between them. The additional layer and air space give triple glazing better insulation value than that provided by double glazing. It is a good choice where extremes in weather and temperature are normal. Triple-glazed windows can help reduce sound transmission where outside noise is a problem.
