Spain: Knauf España has expanded its range of oversize gypsum wallboard systems with the launch of its new Maxiboard boards. The producer said that the boards’ 900mm thickness allows for a 30% reduction in studs, screws and joint treatment in installation. Maxiboard boards are optimal for use in large spaces, including in shopping centres, cinemas and data centres. They offer EI 240-certified fire resistance in systems up to 6m high and EI 120-certified fire resistance in systems up to 11m high.
