Laminated plasterboard consisting of a 100% natural gypsum core tightly bonded to two cellulose sheets. The board characteristics give it type I, D, F, R, H1 classification as per standard EN-520:2004 +A1 2009. This type of board contains additives that reduce water absorption capacity. It is used in applications that require greater surface hardness, higher breaking load strength and better fire protection, thanks to the incorporation of mineral fibres and other additives in the gypsum core to improve its cohesion at higher temperatures. Its special formulation and high density give it greater impact and fire resistance, better insulation against airborne noise and good resistance to humidity in humid areas. It has a nominal thickness of 13 mm, with a nominal width of 1200 mm. The long edges of the board are cardboard-coated and tapered (BA).
