Large-scale renovations involving wet areas require specific materials that can withstand humidity without compromising structural integrity. Purchasing these specialized panels in pallet quantities is the most efficient way to manage substantial projects, such as fitting out multiple bathrooms, utility rooms, or commercial kitchen spaces. These engineered sheets are distinct from standard wallboard due to the inclusion of silicone additives within the gypsum core and water-repellent liners, usually identifiable by their green paper face.

This unique composition significantly reduces the rate of water absorption, preventing the material from degrading, swelling, or warping when exposed to intermittent steam and condensation. While primarily essential for internal partitioning in damp environments, these boards also offer enhanced acoustic and fire performance capabilities. Their durability extends their utility to semi-exposed locations, making them a suitable choice for external soffits in sheltered areas where standard drylining would fail. Opting for volume purchasing ensures a consistent supply for extensive drylining tasks, helping to maintain workflow on site.
