Product catalog summary
Product Specification:
The document describes a resilient acoustic underscreed made from agglomerated cork, polyurethane foams (PU), and EVA, designed for impact noise insulation in floating screeds. It has a density range of 370-500 kg/m³ and offers an impact noise reduction of ΔLw dB.
Key Features:
  • Impact noise reduction and thermal insulation.
  • Long-term resilience.
  • Made from recycled and natural materials.
  • Lightweight and flexible, easy to handle.
Fire Classification:
Classified as E/Efl according to EN 13501-1 and ISO 11925.
Thermal Properties:
Thermal conductivity is 0.0751 W/mK as per ASTM D297.
Standard Dimensions:
  • Thickness: 6/3 mm and 8/4 mm.
  • Width x Length: 1x10 m.
  • Other sizes available upon request.
Physical and Mechanical Properties:
  • Specific Weight: 370–500 Kg/m³.
  • Tensile Strength: ≥200 KPa.
  • Creep Deflection: <1 mm for both thicknesses.
Acoustical Results:
  • ΔLw: 25 dB for 6/3 mm and 27 dB for 8/4 mm.
  • IIC: 53 dB for both thicknesses.
Dynamic Stiffness:
  • 42 MN/m³ for 6/3 mm and 29 MN/m³ for 8/4 mm.
Installation Instructions:
  • Ensure room conditions with temperature > -5ºC and moisture content < 75%.
  • Subfloor should be structurally sound, clean, and level with moisture content < 2.5%.
  • Install a perimeter insulation barrier to prevent lateral noise propagation.
  • Unpack and acclimate Acousticork U36 for 24 hours before installation.
  • Install with the dimpled side down, ensuring tight joints and secure with tape.
  • Cover with a waterproof membrane before screeding.
General Notes:
