window type composed of two pieces of glass separated by a special gas-filled gap between them. All layers are bound together strongly and protect the interior from unwanted heat or coolness loss. Thicker, safer, and much more resistant than single-glazed, double-glazed windows help save energy and significantly lower the power bills. They have a lot of advantages such as noise reduction, lower condensation risk, and eco-friendliness. It all makes them a very popular window choice common in the UK.
