Stravifloor Prefab

Modular System

Stravifloor Prefab* is a pre-manufactured modular floating floor solution that is delivered on site with detailed installation drawings making it exceptionally easy to install whilst minimizing the risk of installation errors.

The CDM Stravitec elastomeric bearings or springs ensure this high-performance floating floor system provides excellent structure-borne and airborne noise isolation.

Main Characteristics

  • Natural frequency: ≥ 6 Hz (with elastomeric pads) or ≥ 2.5 Hz (with springs)
  • Product standard height: 30 mm and 50 mm (elastomeric pads) or 89 mm (springs)
  • Minimum system height: 130 mm (concrete/screed) or 70 mm (timber/cement boards)
  • Minimum air gap: 30 mm

Benefits

  • Specifiers

    For Specifiers

    Guaranteed Acoustical Performance
    • Possible to design with different bearing types (elastomeric bearings, springs, both with different load capacities or natural frequency) to cope with different criteria, both acoustically or load-related
    • Natural rubber bearings provide a low, stable natural frequency over a wide load range, combining high dynamic stiffness with minimal deflection and low creep for long‑term performance
    Design Flexibility & Adaptability to Architectural Constraints
    • Perfect for sloped (up to 50º) surfaces since it's anchored to the support
    • Suitable for retrofit projects due to its lightness and limited build-up height
    • Resistant to uplift forces
    Proven Performance (& Sustainability)
    • Acoustic laboratory test data available
    • No metal components
    Easy to Specify
    • Easily integrate into project documentation and workflows with ready-to-use .dwg cross-sections and editable .doc specifications available online
  • Installers

    For Contractors

    Reduced Installation Time and Labour Costs*
    • Modular and prefabricated solution tailor-made to the room geometry - ideal for large-scale or repetitive layouts where speed matters
    • Comprehensive shop drawings with identification of the position (within the room) of each panel

    • Ensures consistent results regardless of installer experience

      *Installation services available by CDM Stravitec team, or at least installation supervision
