NOTE! Made to order. Minimum order quantity is 1 pallet (30 pcs). Delivery takes place on the next business day after ordering.

Knauf KPS18 is a heavy-duty, fire-protective plasterboard specially developed for constructions with high fire-resistance requirements. The board has a reinforced gypsum core that provides significantly better fire-protection properties than standard plasterboard.

KPS18 is particularly well suited for fire-rated partition walls, protective cladding of timber structures, and encasing building components. It can be used for both new construction and renovation, and is suitable for structures where improved fire protection is required.

The board has paper-faced surfaces and tapered long edges, making joint filling and surface finishing easier. In approved wall constructions, fire rating EI30 can be achieved with a single layer of board.
