MATIMPACT 8/4 is a profiled recycled rubber membrane designed for impact sound insulation beneath mortar, screed or floating slabs. Iti s positioned as the core product in the profiled range, balancing build-up thickness and decoupling performance.

Scope

  • High-performance residential buildings, hotels and offices.
  • Commercial and tertiary-use premises with higher impact sound insulation requirements.
  • Medium-to-high performance floating screeds and slabs.

Advantages & Benefits

  • Balance between thickness and potential decoupling performance.
  • Profiled geometry designed to reduce dynamic stiffness.
  • Enhanced standard product within the profiled MATIMPACT range.

Instruction for Use


  • Prepare the substrate: clean and level the surface, removing debris and any elements that could damage the product.
  • Lay MATIMPACT: butt the sheets together without gaps or overlaps, carefully fitting them all junctions.
  • Isolote the perimeter: install DESOLIDARIZADOR PERIMETRAL along walls, columns and all other vertical junctions, extending above the height of the screed and final finish.
  • Install a separation film before pouring the screed to prevent leakage and acoustic bridges, with a 15 cm overlap.
    *If this separation layer is not instaled, all MATIMPACT membrane joints must be sealed with masking tape.
  • Install the screed or floating slab without displacing or puncturing the film or membrane, respecting the thickness, reinforcement and curing specified for the system.


    • Indications and Important Recommendations

    • Avoid any rigid contact between the floating screed and walls, columns, service installations or vertical elements.
    • Treat the perimeter with a compatible resilient strip and ensure continuity of the elastic layer.
    • Do not puncture the sheet or allow mortar residues to create acoustic bridges.
    • Specify the screed thickness, reinforcement and strength according to the expected loads.
    • Do not use directly beneath the final floor finish unless specifically approved for use as an underlay.
    • The values indicated correspond to the results available at the current stage of product development and may be updated as the industrialisation and validation process progresses.

    Handling, storage and preservation

    • Store in a dry place, protected from the weather, heat sources and direct sunlight.
    • Keep the product in its original packaging until use.
    • Avoid deformations, impacts or pressure points that could alter the profiled geometry.
