Introduced in 2003, the Isosonic Timber Floor system has been used to achieve Approved Document Part E compliance since the current requirements were published. The systems outstanding performance, versatility and cost effectiveness mean that it is perfectly suited to both new-build and refurbishment applications.Benefits
- Exceeds Building Regulation requirements.
- System uses Isorubber Base to reduce noise transfer, this is a tough, resilient acoustic mat.
- Range of ceiling solutions available.
- No long term / short term deformation of acoustic layer.
- Suitable for use with Under Floor Heating.
- Tried and tested solution which has been widely used since 2003.
On site testing shows that the Isosonic Timber Floor system can achieve results of:
Airborne Sound ≥ 50db (Dntw + Ctr)
Impact Sound ≤ 56db (Lntw)
This exceeds the Building Regulation (Approved Document Part E) requirements by 5dB in both cases.

Isorubber Base is a 6mm thick acoustic insulation that is laid over the structural timber deck, separating it from a timber overlay of your choice and absorbing impact sound. The Isorubber Base is turned up at the perimeter to isolate the timber overlay from the walls reducing flanking sound transmission. A durable product with a density of approximately 635Kg/m3, Isorubber Base does not suffer from any deterioration of acoustic performance during the normal lifespan of a building. This is because it undergoes virtually no short term deformation or long term creep deformation under normal domestic loads.
With a recycled content of approximately 90% waste rubber, a Global Warming Potential of Zero and an Ozone Depletion Potential of Zero Isorubber Base provides a means of using problematic waste material to the benefit of the environment.
The Isosonic Ceiling treatment utilises the Isosonic Hanger and Bracket ranges to separate the plasterboard from the joist. The extensive range of Isosonic Hangers and Brackets provide the flexibility to design a ceiling to suit most situations.
The Isosonic Hangers are attached to the bottom or side of the joists and hold 50 x 50mm battens which the plasterboard is then fixed into. An acoustic foam layer within each hanger isolates the battens from the joists, reducing direct sound transfer between the joist and the plasterboard.
The Isosonic Brackets are attached to the bottom of the joists and hold 50 x 50mm battens or standard metal channels which the plasterboard is then fixed into. Specially designed rubber fixings isolate the brackets from the joists, reducing direct sound transfer between the joist and the plasterboard.
Please refer to our Brackets and Hangers page for further information regarding the options available.
Isosonic Ceiling Strip can be used around the ceiling perimeter to help reduce flanking sound transmission.
The Isosonic Timber Floor system consists of 6mm Isorubber Base fitted below a floating timber floor surface of 18mm flooring grade chipboard (or any wooden flooring with a similar mass). The Isorubber Base is fitted over a structural timber deck with 100mm thick low density mineral wool between the joists. An Isosonic Ceiling is also required, consisting of Isosonic Hangers or Brackets fixed to the joists, under drawn with a layer of 12.5mm plasterboard and either a layer of 19mm plasterboard plank or 15mm Soundbloc board.
The extensive site testing carried out on this construction shows that it consistently achieves results well in excess of building regulation requirements.
