Rock Fibre Slabs

    Rock Fibre Slabs are manufactured from non-combustible rock fibre bonded with a high performance binder.
    They are designed for the thermal and acoustic insulation of flat and curved surfaces.
    Rock Fibre Slabs are available in semi-rigid and rigid slabs and in a range of densities to suit almost any thermal or acoustic insulation application. They can be supplied cut to size and shape, and can be faced or totally enclosed in a wide range of materials including aluminium foil, tissue and glass cloth.
Colour - Greyish Brown
   Rock Fibre Slabs are used extensively for thermal and acoustic insulation in domestic, commercial and industrial buildings; in original equipment such as cookers, boilers, tanks, vessels, generators,industrial plant and equipment, ceiling tiles and marine, road and rail transport.
Operating Temperature
   Rock Fibre Slabs can be used at continuous operating temperatures up to 230ºC and up to 850ºC in selected applications. Further details available on request.
Fire Performance
   Rock Fibre Slabs achieve a Euroclass A1 fire rating (non-combustible) when tested in accordance with BS EN 13501-1.
They are non-combustible, when tested in accordance with BS476: Part 4: 1970 (1984).
They comply with the Class 'O' requirements of the Building Regulations, when tested to BS476: Part 6: 1981 and Part 7: 1987.
Thermal Conductivity
Acoustic Performance
   Typical test data is given below for comparative purposes. The letter (S)denotes results obtained with a solid backing and the letter (C) denotes results obtained with a 300mmcavity behind the insulation.
slab1 †NRC (Noise Reduction Coefficient) is the average coefficient over the frequency range250-2000Hz inclusive.

Dimensions and Density
Rock Fibre Slabs can be die-cut to size and shape.
slab2 Note: Other slab sizes, density and thicknesses may be available subject to minimum order quantities. Further details available on request.

    Rock Fibre Slabs are rot-proof, odourless, non-hygroscopic, will not sustain vermin and will not encourage the growth of fungi, mould or bacteria. They do not settle under vibration, when tested in accordance with BS2972: 1975 and are dimensionally stable under varying conditions of temperature and humidity.
