In architecture, a baseboard (also called skirting board, skirting, mopboard, floor molding, as well as base molding) is a (generally wooden) board covering the lowest part of an interior wall. Its purpose is to cover the joint between the wall surface and the floor.
It covers the uneven edge of flooring next to the wall; protects the wall from kicks, abrasion, and furniture; and can serve as a decorative molding.
At its simplest, baseboard consists of a simple plank nailed, screwed or glued to the wall; however, particularly in older houses, it can be made up of a number of mouldings for decoration.
Plastic baseboard is usually available in white or a flexible version in several colors and is usually glued to the wall.
Wooden baseboard can be available in untreated, laquered or prepainted versions. Prepainted baseboards can be made from a single piece or finger jointed wood, often softwoods, while hardwoods are either laquered, or raw for staining and made from a single piece of wood. Radiators are sometimes installed inside or in front of baseboards (baseboard radiators).
A baseboard differs from a wainscot; a wainscot typically covers from the floor to around 1-1.5m high (waist or chest height), whereas a baseboard is typically just up to 0.2m high (ankle height).
