Acoustic Mineral Wool and Membrane

 Membrane & Wool Floor View

Airborne & Impact Noise. Generally installed when old floorboards are being removed and new chipboard flooring is being fitted. Floorboards will be lifted and removed to expose floor joists. Mineral wool is friction fitted between joists. T&G structure deck is fitted over the whole floor area. The flooring will not be fixed to joist as we need to keep the floor floating. Perimeter strips will be installed as standard to minimize flanking noise traveling down the walls.
