curtain

A curtain is a piece of fabric or other material suspended to cover an opening such as a window or doorway, or to create a separation within a room. Curtains serve practical purposes—controlling light, providing privacy, and reducing drafts—and they also contribute to a space’s color, texture, and acoustics. In theater and stage design, curtains (drapery) function to partition spaces and hide equipment, with specialized fabrics and tracks.

Common window curtains come in many varieties. Sheer curtains allow light to pass while offering some privacy, while blackout curtains are dense to block light and improve insulation. Materials range from natural fibers such as cotton, linen, and silk to synthetics such as polyester and blends. Shower curtains, in contrast, are typically water-resistant and may be vinyl, plastic-coated polyester, PEVA, or fabric with a water-repellent finish. Curtain headings include rod-pocket, tab-top, back-tab, and grommet styles, and drapery headings include pinch-pleat, goblet, and other pleat designs. Liners add opacity and insulation.

Installation and care: Curtains are mounted on a rod or track system. Measurements should account for width, desired fullness, and length, with options for floor-length or sill-length. Fabric curtains are usually machine-washable; vinyl and coated fabrics require wipe-down. Iron or steam as needed, following care labels. Regular dusting or vacuuming helps prevent buildup; avoid high heat on synthetic fabrics. Corded window coverings can pose entanglement risks, so many jurisdictions recommend cord safety practices.

History and usage: Curtains have long been used in many cultures to regulate light and air and to reflect social status. The development of glazed windows spurred widespread use of curtains, and modern options emphasize ready-to-hang, machine-washable varieties in diverse styles.
