Product catalog summary

Product Specification
The document details a resilient acoustic underlayment made from agglomerated cork and recycled SBR rubber, bonded with polyurethane elastomer. It is designed for impact noise insulation in ceramic, natural stone, and wood-based floors, with a density of up to 650 kg/m³.

Key Features

Homogeneous material with cork and rubber granules sized 0.5-1mm.
High durability and resilience.
Effective performance with reduced thickness.
Low residual indentation and no plasticizer migration.

Technical Properties

Specific Weight: 560–650 kg/m³.
Tensile Strength: > 600 kPa.
Compression at 0.7MPa: 15–30%.
Recovery after 0.7MPa: > 75%.

Technical Data Sheet

Flooring types include ceramic, natural stone, and wood with varying thicknesses and thermal resistance.
Compressive strength and water vapor resistance are specified for wood flooring.

Acoustic Results

Impact Insulation Class (IIC) and sound transmission data are provided for different flooring systems.
Graphs illustrate normalized sound pressure levels across frequencies for various floor types.

Installation Instructions

General guidelines emphasize the importance of following manufacturer instructions, especially regarding adhesives.
Specific steps for glued and non-glued floors are outlined, including subfloor preparation and acclimatization.
Critical conditions include substrate humidity below 2.5% and air temperature above 10°C.

Important Notes

Mechanical fastening of the underlayment is discouraged to maintain acoustic properties.
Vapor barriers are necessary for wood or laminate floors.
