Plaster & Plasterboard

Plasterboard and plasterboard are flexible building materials that play an important role in improving the structural and visual appeal of construction projects.

Plaster

Plaster is a finishing material that creates smooth and durable surfaces on walls and ceilings, and also has a wide range of applications, from residential to commercial settings, where it serves as a great canvas for paint or other decorative finishes. Plaster's versatility makes it an essential component in both new and renovation projects, allowing builders to produce a polished and refined appearance.

Plasterboard

Plasterboard, a popular and practical choice, is widely used in present building procedures. Plasterboard, also known as plasterboard or gypsum board, is made up of gypsum layered between layers of paper to provide a strong and easy-to-install surface. This material is essential for constructing partitions, ceilings, and interior walls. Its versatility makes it appropriate for a wide range of settings, from homes and businesses to industrial areas.

Plasterboard comes in a wide variety of options depending on the unique project needs. Standard plasterboards are good for most applications, whereas moisture-resistant varieties are ideal for damp areas such as bathrooms and kitchens. Fire-resistant plasterboards provide increased safety, making them vital in commercial settings and high-risk locations.

And at Howarth Timber, we provide a carefully selected range of plaster and plasterboard options to guarantee that your building projects use the right materials for the job.
