rock wool The RW panel is constituted by two sheet with inter posed layer of oriented fibre high density rock wool,arranged perpendicularly to the plane and positioned in strips,laid longitudicularly with offset joints and transversally compacted, completely filling the space between the two supports. Resistance to fire Rook wool is non-combustible material,so the rock wool panel has goodfire-resisting property. The test shows the temperature of the panel, the test results obtained by istituto GiordanoS.P.A is as following: Roof and wall panel thickness 100 REI 120 Roof and wall panel thickness 80 REI 60 Roof and wall panel thickness 50 REI 30 The roof and wall panel,thickness 50-80-100mm,were classified 0/1 forreaction to fire.(material are assigned a class from 0 to 5,the higher the class,the higher the degree if combustion.
