Businesses in the plaster building products category manufacture, distribute or sell materials used to form, line and finish walls and ceilings. Their products commonly include plasterboard, plaster and gypsum-based compounds, as well as specialist boards designed for uses such as moisture resistance, fire performance or sound reduction. Some suppliers also provide dry-lining systems and related materials for new construction, refurbishment and repair work. Associated products may include metal or timber framing components, jointing tape and compounds, corner beads, plastering accessories, fixings and finishing materials. Customers can expect advice on product types and compatibility, along with supply for trade and, in some cases, domestic projects. Products are used by plasterers, builders and other construction professionals to create smooth internal surfaces, partition rooms, improve wall or ceiling performance, and prepare surfaces for decoration.
