2FT45
PRODUCT DESCRIPTION

2FT45 (Part Code A180) or 2FT80 (Part Code A190) is a soundproofing composite made up of the polymer-based, asphalt-free 5kg/m² or 8kg/m² synthetic acoustic membrane bonded both sides with a 10mm layer of porous acoustic felt mats, both formed in such a way as to offer excellent acoustic insulation in different building elements: walls, ceilings, roofs, etc.

PROPERTIES
High acoustic insulation, combined with soft, flexible elements (plasterboard, wood conglomerate).
  • Easy handling and application. (does not make you itch !)
  • Easy overlapping.
  • Cold- and heat-resistance.
  • Self-extinguishing.
  • Excellent ageing resistance.
  • Rotproof

    PACKAGING AND STORAGE
    The product is supplied in two types of superficial density:

    USES
  • Soundproofing of horizontal (ceilings) and vertical enclosures, where excellent soundproofing against airborne noise is required.
  • Specially recommended between block or partition cavity walls.
  • Can be used between joists as a higher performance alternative to our acoustic quilt.
  • Soundproofing against airborne noise in flat roofs.
  • Can be fixed against a wall with framework pushed against it for improved isolation and noise reduction.
    For further information see examples in systems sheets.

    2FT45 is also an ideal material for closing plenum cavities above partition walls to dramatically reduce noise transfer. Especially suited to lightweight suspended ceilings where the partitions do not go completely up to the structural ceiling soffit.

    Using 2 separate layers of 2FT45 with a 50mm airgap between will significantly reduce the crosstalk noise between adjacent rooms.

    If the ceiling hangers can take the extra weight then additional mineral wool can be placed behind the tiles for further absorption.

    Approx. 4 plastic rossettes per sq.m. (along with our spray adhesive) should be used when fixing the 2FT45 / 2FT80 to walls or ceilings.

    PRODUCT DESCRIPTION

    FT 75 is a soundproofing composite made up of the polymer-based, asphalt-free 7.5kg/m² synthetic acoustic membrane bonded one side with a 10mm layer of porous acoustic felt mats, both formed in such a way as to offer excellent acoustic insulation in different building elements: walls, ceilings, roofs, etc.

    USES
  • Soundproofing of horizontal (ceilings) and vertical enclosures, where excellent soundproofing against airborne noise is required.
  • Specially recommended in partition walls.
  • Soundproofing against airborne noise in ceilings.
  • Reduction of impact noise level in all types of floors, applied underneath the flooring.
  • Can be fixed over frameworks before the plasterboard sheets are attached for improved isolation and sound blocking.
  • Can be fixed against a wall with framework pushed against it for improved isolation and noise reduction.
    For further information see examples in systems sheets.

    INSTRUCTIONS FOR USE
    Installation of the membrane: Prior to installation of the membrane on the substrate, STAPUT Adhesive must be applied to both the substrate and the complex, allowing it to dry tacky before applying the composite. Align the 2FT complex on the substrate, and install.

    Laps: Overlap 5 cm both vertically and horizontally. Care must be taken to always seal the laps correctly, either with adhesive or tape, as small openings can considerably reduce the level of acoustic insulation required.

    SUPPORT
    2FT lends itself to all types of normal building substrates. The substrate must be even, clean and dry, and preferably rendered. If the rendering is old, its condition must be checked to avoid adherence problems of 2FT to the rendering.
    • RW 53dB INTERNAL PARTITION SOLUTION 1

    Interior partition comprising a 50mm central stud frame, acoustic mineral wool infill, FT 40 composite fixed to one face with 2 layers of 12.5mm plasterboard fixed either side of the frame.

    The system below was tested with the lighter 4kg/m² composite. Performance would be improved by around 3dB using the 7.5kg/m² material.


  • 1. 2 layers of 12.5mm plasterboard.
  • 2. Neoprene isolation tape around perimeter.
  • 3. FT 40 or FT 75 (felt side against plasterboard).
  • 4. 50mm thick 60kg/m³ acoustic mineral wool.
  • 5. Flooring.
    (All perimeters finished with acoustic sealant).
