Abstract (en)
[origin: WO2022101472A1] The present invention concerns a fire-resistant board at least classified B15, comprising a core (1c) sandwiched between two facers (1f) and comprising at least 80 wt.% calcium sulphate dihydrate and at least 2.3 kg / m³ glass fibres. A groove (3) extends along each of the first and second longitudinal edges for forming a spline joint with a second board. The boards can be produced in large dimensions of up to 3050 mm length and higher, while still being hand able due to their low density of 0.35 and 0.65. The present invention also concerns a laminate formed by a board as defined supra sandwiched between two high-pressure layers (HPL).The laminates can be joined with one another by spline joints to form a partition system particularly suitable for forming bulkheads, deckheads, and partitions in general, as well as floors and ceilings, pieces of furniture, and the like in sea-going vessels (= ships) and offshore platforms.
