Plasterboard
Plasterboard, often called drywall, is made from two outer layers bonded around a core of gypsum. It is a popular choice for construction because it is lightweight, easy to handle, and cost-effective.
Uses for Plasterboard
Modern plasterboards can be used in many projects, including:
- To control moisture – Ideal for areas exposed to steam or humidity, such as bathrooms and kitchens. Moisture-resistant plasterboard is specially designed to repel water, preventing it from being absorbed.
- Thermal heating in buildings – Useful for solid-wall buildings with less insulation than cavity walls, helping improve thermal performance.
- Restricting sound – Soundproof plasterboard has a higher density and can be part of a larger soundproofing system, reducing noise transfer through walls and ceilings.
- Fire resistance – Fire-resistant plasterboard contains special fillers and fibres that help slow the spread of fire.
- Acoustic soundproofing – Acoustic plasterboard is designed for ceilings and wall linings, offering higher sound insulation by blocking and absorbing soundwaves.
Strength and Durability
Plasterboard provides a smooth, high-quality finish for walls and ceilings. It is also suitable for use in lift shafts, stairwells, corridors, and auditoria, where durability is important.
Decorative Options
Our range also includes coving – a decorative moulding that hides the joint between walls and ceilings. Coving adds a clean, stylish finish and can enhance the character of any room.
