To stand the best possible chance of passing your Sound Test it is important not only that you use the right products but also you fit them correctly.

Below is a list of the major problem causes that normally arise during a Sound Test. Please be sure to check these off one by one for each room in the building so that problems can be solved at the earliest opportunity. (Some items may not apply to your construction).

  • Ensure the insulation fills the whole width of void, also pack around pipe work

  • Ensure that the sub-floor is watertight and sealed with mastic or silicon

  • Ensure that the plasterboard on any walls is complete right down to sub-floor, seal all gaps

  • Ensure you use the isolation tape around the wall of each room

  • If installing floating screed ensure all isolation layer joints are overlapped and taped

  • Ensure that the Acoustic floor is fitted with staggered joints

  • Ensure all the Acoustic floor is sealed watertight even around heating pipes

  • Ensure plasterboard is fitted with staggered layers and all joints sealed

  • Do not nail or screw through an Acoustic Floor

  • If using Resilient Bars ensure that they are fitted as per manufacturers recommendations

  • Ensure that any RSJ’s or supporting steel work is insulated and isolated from plasterboard

  • Ensure all waste pipe service runs are boxed in with insulation and plasterboard

  • Do not fit carpets or laminated flooring before you have passed the test

  • You must fit doors and windows before the test is carried out
