Application

Suitable for conversion projects where there is an existing floor surface and a shallow floor build up is required.

Description

Shallow acoustic overlay boards designed to damp vibration and attenuate impact and airborne sound passing through floors with minimum loss of room height. They comprise substrate layers of moisture resistant MDF combined with either fibreboard or cement particleboard separated by sound damping strips. A resilient layer of acoustic felt is adhered to the underside.


Features and benefits:

  • Shallow construction - only 17 or 21 mm.
  • Acoustic chipfoam contours over minor irregularities.
  • Can meet Building Regulations (E&W) Approved Document E with resilient bar ceiling.
