Acustisol Acoustic Insulation

Acustisol Acoustic Insulation

Acustisol is an insulating and absorbing material made of an elastomeric layer and a substrate made of rubber fragments that give it its characteristic vibration absorption and the necessary rigidity for good performance under loads.

It is particularly suited to insulating floors and walls of main construction structures with respect to solid transmission of vibrations.

Applications

  • Separating walls, support of faces and double walls.
  • Overlay flooring, benches and inertia bases.
  • Insulation of vibration in general.
  • Improved structural insulation in joints.

Technical characteristics

  • Load of work : 100 to 500 Kg/m2
  • Presentation :  Roll 5.000 x 1.000 mm
  • Thickness :  8 mm
  • Weight :  5 Kg/m2
  • Global improvement vibrations : 20 dB
  • Global improvement impact noise DLw :  20 dB
  • Acoustic Insulation to 125 Hz :  27 dB

Installation

On-site preparation

Surfaces should be free of debris and there should be no irregularities of over 5mm/cm² in order to prevent an excessive deflection of the elastic layer which might cause an acoustic bridge. An uniform layer of mortar may be applied if necessary.

Acustisol Assembly

A layer of Acustisol is applied with a roller with the smooth side of the asphalt material facing up and the granulated side in contact with the ground, avoiding empty corners and ensuring total continuity between joints. Where the surface meets vertical elements (walls, pillars, pipes crossing the floor, etc) the material shall be raised 20cm around or along the element to avoid contact with the concrete.

Piping (water, downpipes, etc) which cross the concrete slab and the Acustisol should be envelopped with a protecting facing to avoid coming into contact with the concrete (perimeter baseboard).

Horizontal service piping should be installed under the Acustisol.

Protective plastic

In order to avoid a possible infiltration of concrete through the Acustisol joints, a plastic sheet with a thickness of over 100 microns should be placed over the entire surface. Joints should overlap by at least 10cm and should overhang the baseboard by 20cm on vertical elements.

Concrete slab

We recommend a minimum 4cm thick concrete slab (minimum workload of 100 kg/m²) with a mesh (6mm to 8mm diameter rods with a 15cm x 15cm grid depending on the weight supported by the concrete slab).
