Acousticork_U85_ACS

Product catalog summary

Product Specifications
The document describes a resilient acoustic underscreed made from agglomerated cork, recycled polyurethane foam, and recycled rubber, bonded with a PU elastomer. It is designed for impact noise insulation of floating screeds, with a density range of 280 to 400 kg/m³ and an impact noise reduction of up to 23 dB. Key features include impact noise reduction, thermal insulation, ease of handling, and use of recycled materials.

Thermal Properties
Thermal conductivity is specified at 0.0692 W/mK, tested according to EN 12664:2001 and ISO 8302:1991.

Physical and Mechanical Properties
The specific weight ranges from 280 to 400 kg/m³, tensile strength exceeds 150 KPa, and recovery after 0.7 MPa is greater than 75%, tested according to ASTM standards.

Acoustical Results
Standard dimensions include thicknesses of 3 mm and 4/2 mm, with corresponding ΔLw values of 21 dB and 23 dB, and IIC values of 50 dB and 52 dB. Testing follows ISO and ASTM standards.

Installation Instructions
Installation involves placing the Acousticork U85 over a structurally sound and level subfloor, with a perimeter insulation barrier to prevent lateral noise propagation. The material should be unpacked 24 hours prior to installation and cut to fit. A waterproof membrane must cover the entire area before screeding. Mechanical fastening is discouraged to maintain insulation performance.

General Notes
The data provided are typical values and not intended for specific application suitability. For detailed installation instructions, contact Amorim Cork Composites.
