garage curtain

A garage door is a large door allowing access to a residential garage, commercial garage, or facility that opens either manually or via a motorized garage door opener. Garage doors are often large enough to accommodate cars and sometimes other vehicles or equipment. The operating mechanism is usually spring-loaded or counterbalanced to offset the door's weight and reduce the effort required to open and close it. Some doors can have no counterbalance mechanism and be fully motor-driven, often in commercial applications.
Garage doors are made of wood, metal, or fiberglass, and may be insulated to reduce heat loss. Less commonly, some garage doors slide or swing horizontally or vertically.
