(Formerly Isolgomma) See Isolgomma or Acousticel leaflet for technical details


Suitable for new build and conversion of separating floors contained in buildings of two storeys or more. Please note, as the structures of floors and their supporting walls varies significantly with each individual building, it may be necessary to install additional insulating measures in some cases. In the case of a newly sound insulated separating floor failing a test, contact our technical department for advice.

A resilient recycled rubber insulation providing effective sound loss when installed beneath the floor surface. Its unique formulation compensates for minor irregularities in existing floor constructions and complies with the Building Regulations for conversion and new build of both suspended timber and concrete floors. 10mm thick R10 can be laid onto existing or new timber and concrete floors with the final floor surface directly on top.

Fixing Instructions

Preparation for Conversions

Ensure there are no holes or gaps in the floor to be treated. Small gaps can be filled with mastic, or for more severe problems, overlay with our Sound Barrier Mat SBM5 which should be securely glued and fixed before commencing treatment. The floor surface should be flat and level so concrete floors may need treating with a levelling compound or screed.

Installing Floating Floor

R10 is supplied in rolls which are unrolled and laid on the floor wall to wall with the edges butt jointed. If a wood based floating floor is to be used, it is not necessary to lap the insulation up the walls. Trimming can be done with the aid of a sharp craft knife and offcuts can be re-used. If the floating layer is 22mm t&g chipboard or 19mm t&g QuietBoard cement impregnated chipboard, this should be laid with the joints glued using a normal PVA adhesive. If two layers of 12mm QuietBoard cement impregnated chipboard are to be used as the floating layer, these should be laid directly on top of the R10 one layer at a time with the second layer overlapping the joints of the first and spot bonded adhesive before screwing together with 25mm length screws. Cutting of the boards can be achieved with either tungsten or diamond tipped blades or a metal cutting blade if using a jigsaw. Usual dust prevention measures must be taken when handling and cutting any product that creates dust. In all cases, the floating layer should be fitted to within 5-6mm (1/4") of the surrounding walls. This gap can be sealed with our Acoustic Sealant when fitting of the floor is complete. No mechanical fixings must be used which would penetrate the insulation.

NOTE: If a reinforced sand/cement screed is to go on top of the R10, the insulation must be laid FELT SIDE UPPERMOST with the joints overlapped by 50mm and lapped up the walls to contain the screed. The mesh should then be laid prior to installation of the screed which must be a minimum thickness of 65mm. The insulation can be trimmed down to floor level once the screed has cured. When applying the skirting boards, allow a 2-3mm gap between the skirting and the top of the flooring. This gap should not be filled.

Dividing Walls or Partitions

Load bearing and studwork partitions should be constructed from the base floor before installation of floating floors. Under no circumstances should R10 be used as a load bearing component. 10mm thick Acousticel M10AD can be used as a resilient insulation between studwork and substrate if required which can be easily cut with a jigsaw.
