Acoustiblok Ceiling Applications

Acoustiblok Ceiling ApplicationsQuietFibre® or a similar type of dense acoustic open cell cavity stone wool / fibre should be fitted into all cavities where appropriate prior to the fitting of Acoustiblok Insulation Membrane. This will offer a thermal insulation value at the cavity but critically will prevent resonance within the cavity which left if left unfilled could lead to a potential amplification of any sound wave. Acoustical sealant would ideally be applied along all joists prior to the Acoustiblok membrane being gently pulled across the joists and secured in way of mechanical fixings to hold in place. All overlaps or joins of Acoustiblok membrane should be sealed with acoustic silicone sealant and tape jointed (please see accessories) to ensure an air tight seal to the entire area and at the perimeter.

As an option, a resilient bar / channel can be fitted perpendicular to the joist at this stage if tolerances allow and in doing so, the Acoustiblok will be further supported in place. The resilient channel also offers a secondary decoupling of the finish ceiling materials from the substrate.

The chosen finishing board system of either a single / double staggered board can then be installed to the ceiling.
