Window shades are a type of window covering that can be used to block out light, provide privacy, and reduce energy costs. The four solutions for the term window shade are TINT, EAVE, AWNING, and BLIND. TINT is a thin film applied to glass to reduce the amount of light that passes through it. An EAVE is the lower edge of a roof that projects beyond the side of a building. An AWNING is a roof-like structure that is attached to the exterior of a building and provides shade from the sun. Lastly, a BLIND is a window covering made of horizontal or vertical slats that can be adjusted to control the amount of light entering a room.
