Plaster & Plasterboard

Plaster and plasterboard are versatile building materials that enhance both the strength and appearance of construction projects.

Plaster is a finishing material that creates smooth, durable surfaces on walls and ceilings.

Its flexibility makes it ideal for both residential and commercial projects, providing a perfect base for paint or decorative finishes. In new builds or renovations, plaster delivers a polished and professional look.

Plasterboard, also called gypsum board, is a practical, widely used material in modern construction. It is made from gypsum sandwiched between sheets of paper, forming a strong and easy-to-install surface. Plasterboard is essential for building interior walls, partitions, and ceilings. It is suitable for homes, offices, and industrial spaces.

Different types of plasterboard meet specific needs:

  • Standard plasterboard is suitable for most projects.
  • Moisture-resistant plasterboard works well in damp areas such as bathrooms and kitchens.
  • Fire-resistant plasterboard increases safety in commercial and high-risk locations.

At Howarth Timber, we provide a carefully selected range of plaster and plasterboard products, ensuring your construction projects always have the right materials.
