<p>A method of making a fire resistant building panel comprising two outer panel elements and an inner core sandwiched between the two outer panel elements is disclosed. The two outer panel elements are manufactured from a composition comprising particles of an exfoliated vermiculite, which particles are resinated with a thermosetting resin. The composition is formed into a layer and pressed at a suitable temperature and pressure to a thickness of between 3 mm and 9 mm and a suitable density. Thereafter, the two outer panels are adhered on either side of an inner coreto form the building panel. The building panel has good fire resistant properties.</p> |
