Timber and Steel Floors

A key principle of sound insulation is isolation and in a previous top tip we have highlighted debris in the cavity. This simple top tip is to maintain the sound insulation in floors and ceilings.

In a number of cases, particularly the timber and steel separating floors, Robust Details specifications require the use of a ‘resilient’ ceiling system. Typically these are based around the use of proprietary resilient ceiling bars or, possibly, hangers.

The aim of the resilient ceiling system is to provide a level of isolation by creating an indirect, rather than a direct, connection between the ceiling finish and the structural floor. In order to be sure that the required sound insulation performance can be achieved, it is therefore very important that any resilient ceiling system is installed correctly and not compromised.

So check that the bars are the correction specification, take care over the length of the screws and you will be fine.
