Non-combustible Knauf Brio boards are simple and fast to lay, requiring no special skills for a perfect job. The 600 x 1,200mm boards are laid directly over underfloor heating and cooling systems, typically where the pipe array is installed in metal diffuser trays over moulded insulation. The precise tiered edges are glued with Knauf Brio Joint Adhesive, and screwed together to ensure a solid bond. The new floor can take traffic as soon as the glue has hardened, normally in just a few hours.
