Airborne & Impact Sound Insulation - Concrete Floors
The classification 'Concrete Floor' includes any construction providing a high surface mass. This includes: cast concrete, pre-stressed concrete planks and some beam & block arrangements.
In general, significant improvement in airborne sound insulation is limited due to the existing performance level associated with high mass floors. Upper surface treatment techniques capable of showing major improvements are necessarily substantial (e.g. a thick cementitious screed on a deep resilient isolating layer or even a separate cast slab mounted on anti-vibration mountings). In consequence, examples of these constructions are not included here. Our Technical Section would be pleased to offer advise on such treatments on request.
The most commonly employed treatments are: building boards on resilient layers (composite floating floors); under screed resilient layers and 'soft floor coverings'. All methods provide substantial improvement in impact sound transmission. Only the former two techniques however, exhibit any potential for improvement in airborne sound transmission.
