Asbestos products are materials that contain asbestos fibres, historically used in buildings, industrial equipment and transport because they provided heat resistance, insulation and strength. Examples include asbestos cement roofing and wall sheets, pipe lagging, insulation boards, floor tiles, textured coatings, gaskets and fire-resistant panels. Many remain in older buildings and equipment, where they can pose a health risk if damaged or disturbed. In the UK, businesses associated with this category generally help identify, assess and manage existing asbestos-containing materials rather than supply new products. Services may include asbestos surveys, sampling and laboratory testing, condition assessments, management plans, encapsulation or repair, and removal and disposal by appropriately licensed contractors where required. Work is governed by asbestos safety regulations; the need for a licence depends on the material and type of work.
