Isorubber Contract is an acoustic isolation and vibration reduction mat that provides a fixed resilient layer for floor construction. It is primarily used in concrete floor systems to achieve Approved Document Part E compliance but can also be used in general sound proofing applications.

Product Benefits:
  • Only 3mm thick.
  • Continues to perform for the lifetime of the building.
  • Suitable for use with under floor heating.
  • Simple installation
Roll Size: 3mm x 1m x 20m

Roll Weight: 36Kg (11 Rolls per pallet)

Density: 640Kg/m3
Approved Document Part E Compliance

Isorubber Contract can be fitted over minimum 65mm sand & cement screeds, minimum 40mm proprietary screeds, power floated concrete surfaces or levelling compounds. The structural floor must be a minimum mass of 300Kg/m2 per unit area. Compliance can be achieved with all masonry external flanking wall constructions (600 – 800Kg/m3, 1350 – 1600Kg/m3 & 1850 – 2300Kg/m3). A metal frame ceiling with a minimum void of 100mm or an Isosonic acoustic ceiling is also required. Both ceiling details are under drawn with a layer of gypsum based board (minimum 8Kg/m2).

Mineral wool can be included in the ceiling void to improve test results, this is recommended in beam & block constructions, as they have a lower mass than pre-cast plank and in-situ concrete floors.

Isorubber Contract is a 3mm thick acoustic insulation that is adhered to a floor surface, absorbing impact sound and vibration at source. It is an incredibly durable acoustic underlay with a density of approximately 640Kg/m3. Isorubber Contract provides an extremely cost effective method of achieving Approved Document Part E compliance when carrying out pre-completion testing.

Isorubber Contract is very easy to install and is suitable for use with many types of hard and soft floor coverings. A composite of sustainably sourced, granulated cork and recycled waste rubber Isorubber Contract has a Global Warming Potential of Zero and an Ozone Depletion Potential of Zero. Isorubber Contract provides a means of using problematic waste material to the benefit of the environment.
