Robust Detail E-FC-9

Robust Detail E-FC-9 is an acoustic solution for precast plank floors. This system exceeds the requirements of Approved Document Part E and when registered with Robust Details Ltd removes the requirement for on-site sound testing.

System Summary

Robust Detail E-FC-9 is a fixed, resilient surface layer acoustic insulation system for precast plank floors making it perfect for sound proofing and noise reduction applications.

The system consists of 3mm thick Isorubber Top or Isorubber FR adhered to the screeded surface of a Precast Plank floor using Isobond Adhesive and an MF Ceiling below.

Benefits

  • Exceeds Building Regulation requirements.
  • No need for sound testing if registered with Robust Details Ltd.
  • System uses Isorubber Top, a hard-wearing acoustic covering to reduce noise transfer.
  • Isorubber Top is only 3mm thick, minimising construction depths.
  • No long term / short term deformation of acoustic layer.
  • Suitable for use with Under Floor Heating

Components & Specifications

Acoustic Performance

As a Robust Detail the E-FC-9 system must consistently achieve a site test mean average:

Airborne Sound ≥ 50db (Dntw + Ctr)

Impact Sound ≤ 57db(Lntw)

This exceeds the Building Regulation (Approved Document Part E) requirements by 5dB in both cases.

Isorubber Top

Density  600kg/m³
Roll Size  3mm x 1m x 20m
Roll Weight 42Kg (11 Rolls per pallet)
Isorubber Top is a 3mm thick acoustic insulation that is adhered to a floor surface, absorbing impact sound and vibration at source. A durable acoustic underlay with a density of approximately 600Kg/m3, Isorubber Top has excellent impact energy absorption properties.

Isorubber FR

Board Size  3mm x 1m x 20m
Board Weight  Approx. 42Kg – 3mm variant (11 Rolls per pallet)
Density  610kg/m³
Isorubber FR is an acoustic insulation available in a standard 3mm thickness with others sizes available to order, but only the 3mm version falls under the Robust Detail scheme. It is adhered to a floor surface, absorbing impact sound and vibration at source. It is an incredibly durable acoustic underlay with added fire retardant.

About System

The E-FC-9 system is designed to be easy to install, helping to reduce the risk of workmanship errors. Isorubber Top / Isorubber FR provides a compatible base for almost all types of floor covering including carpets, vinyl, stone, ceramics, solid wood and laminates. It also provides substantial cost savings over more traditional floating floor systems.

The E-FC-9 system consists of 3mm Isorubber Top or Isorubber FR fitted over a minimum 65mm sand & cement or minimum 40mm proprietary screed. The structural floor must be a minimum 150mm precast plank with a minimum mass of 300Kg/m2 per unit area. This system can be used 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, under drawn with a layer of gypsum based board (minimum 8Kg/m2) is also required.

The extensive site testing carried out for Robust Detail classification and the subsequent monitoring tests show that the E-FC-9 system can achieve 3 Code for Sustainable Homes Credits, subject to pre-completion testing. The E-FC-9 system can also be, and is frequently, used in non Robust Detail specifications, subject to pre-completion testing.
