Window technology refers to the advancements in the design and materials used for windows in buildings. This includes energy-efficient glass, which helps to reduce heat loss and improve insulation. Modern windows often feature double or triple glazing, where two or three layers of glass are separated by air or gas-filled spaces, enhancing thermal performance. Additionally, window technology incorporates smart features, such as automated shading systems and self-tinting glass. These innovations allow windows to adapt to changing light conditions, improving comfort and energy efficiency. Overall, window technology plays a crucial role in sustainable architecture and energy conservation in buildings.
