    • Availability in a range of densities 


    Versatile building slabs for a wide range of general building applications, ROCKWOOL RW semi-rigid and rigid slabs are high quality resin bonded slabs that can be used for thermal, acoustic and fire resistant insulation in general building applications.

    The slabs are available in a wide range of thicknesses and densities to suit most requirements. CE marked to EN 13162 and Euroclass A1 non-combustible


    Fire: All Rockwool RW slab products, either un-faced or with an aluminium foil or glass fleece on one or both surfaces, achieve an A1 classification in accordance with BS EN 13501-1 and therefore comply with the requirements of non-combustible materials/products, as defined in all UK and Ireland Building Regulations.

    Acoustic performance: ROCKWOOL stone wool products work in two distinct ways to reduce noise, either by impeding the transmission of sound through an element of the structure or by absorption of sound at the surface.

    The structure of the fibres in ROCKWOOL RW slabs make them ideal for use as a sound absorber.

    Internal partitions

    Dwellings: In England and Wales, Approved Document E requires all internal walls between a bedroom or room containing a WC and another room to have a minimum sound insulation of 40 Rw dB. This applies to new walls built both in dwellings formed by a material change of use and new build extensions of existing dwellings. (For Scotland, the minimum sound insulation requirement is 43 Rw dB).

    Schools: Specific performance standards are set for airborne sound insulation between spaces by Building Bulletin 93 (December 2014) ‘The Acoustic Design of Schools’.

    This classifies each room for the purpose of airborne sound insulation by its activity purpose and sets the minimum sound insulation performance standards for each partition.

    Hospitals: Similar to schools, the Healthcare Technical Manuals HTM 08-01 (previously HTM 2045) sets standards for privacy according to room type and from this the specific performance requirement for any partition can be obtained.
