s. Battens are also used in metal roofing to secure the sheets called a ''batten-seam roof'' and are covered with a ''batten roll joint''. Some roofs may use a grid of battens in both directions, known as a ''counter-batten system'', which improves ventilation. Roofing battens are most commonly made of wood or metal, but can be made of other materials.

Wall battens

''Wall battens'' like roofing battens are used to fix siding materials such as tile or shingles.

construction battens may be used to strengthen panels made up of multiple boards, as in a batten door, or to cover joins.

Wall insulation

Battens are used for solid wall insulation. Regularly spaced battens are fitted to the wall, the spaces between them filled with insulation, and plasterboard or drywall screwed to the battens. This method is no longer the most popular, as rigid insulation sheets give better insulation (with battens bridging the insulation) and take less time to fit.

Batten luminaires are typically cheap and meant to be fixed directly to structural battens in loft spaces or to ceilings and soffits in back-of-house areas where aesthetic value is not required. Fluorescent fittings may include a low-specification diffuser cover, or simply have the fluorescent tube exposed.

Sailing

sailing Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ''ice'' (iceboat) or on ''land'' (land yacht) over a chosen cour ...
