Fibotherm lightweight insulation blocks density 850Kg/m3 are manufactured from fibo ExClay expanded lightweight aggregates and a mixture of other naturally occurring raw materials and cement.
Fibo Exclay is manufactured from a special kind of clay which through heat expansion is transformed into lightweight porous granules with numerous cavities. This is what gives Fibotherm blocks their incredible lightweight properties.
Produced in solid form, Fibotherm expanded clay blocks are extremely lightweight, grey in colour and give an open texture finish. The faces of the Fibotherm block provide the ideal key for plastering.
Fire Resistance Fibotherm insulation blocks are manufactured using Class 1 aggregate. fibro ExClay is processed at approx 1150ºC – melting point is in excess of 1250ºC.
