Isocheck Acoustic Cavity Barrier

Acoustic Wall System

Our Acoustic Wall System (the Isocheck high performance Acoustic Cavity Barrier) is designed to maintain the acoustic separation potential of a partition wall by treating the voids beneath and above the partition.

Isocheck Acoustic Cavity Barrier consists of a single or double layer of 10mm semi-rigid acoustic foam bonded to 12.5mm high density, square edged fibre-reinforced gypsum board. It is easy to install solution to airborne noise transfer from adjacent areas and greatly improves privacy.

Acoustic Cavity Barrier is suitable for within all types of ceiling and floor void spaces including raised access flooring and suspended ceilings.
