An attic is a space located directly under the roof of a building, often used for storage. It can be accessed by a staircase, ladder, or pull-down stairs. Attics are typically unfinished, meaning they may have exposed beams and insulation, but some are converted into living spaces, such as bedrooms or offices. Attics can be found in various types of buildings, including houses and barns. They provide extra space for items like holiday decorations, old furniture, or seasonal clothing. Proper ventilation and insulation are important in attics to prevent moisture buildup and maintain energy efficiency in the home.
