T51 protection

Product catalog summary

Product Specification
The document describes a resilient acoustic underlayment made from agglomerated cork and recycled SBR (Styrene Butadiene Rubber) with a polyurethane elastomer bonding agent. It is designed for impact noise insulation for LVT, SPC, or WPC flooring, with a density of up to 790 kg/m³.

Key Features

Homogeneous material composed of cork and recycled rubber granules (0.5-1mm).
High durability and long-term resilience.
High performance with reduced thickness.
Low residual indentation and free of plasticizer migration.

Technical Properties

Specific Weight: 690–790 kg/m³ (43–49 lb/ft³).
Tensile Strength: > 700 kPa.
Compression at 0.7MPa: 20–45%.
Recovery after 0.7MPa: > 75% (ISO 7322).

Technical Data Sheet

Flooring: LVT.
Thickness: 2.0 mm.
Thermal Resistance: Not applicable.
Punctual Conformability: > 0.5 mm.
Compressive Strength: > 200 kPa.
Water Vapor Resistance: Not applicable.

Acoustic Results

Impact Insulation (IS): Not specified.
IIC | ΔIIC: 69 | 16 dB (ASTM).
Sound Transmission (STC): Not specified.

Installation Instructions

Open packaging 48 hours in advance for acclimatization.
Ensure subfloor is leveled, dry, clean, and structurally sound.
New concrete slabs must cure for 120 days before installation.
Humidity content must not exceed 2.5%.
Air temperature should be above 10°C and humidity below 75%.
Install underlayment perpendicular to the final floor direction.
Do not mechanically fasten the underlayment.
Follow flooring manufacturer's installation instructions.

Important Notes

Never mechanically fasten the Acousticork T51 to the flooring as it diminishes acoustical value.
Do not install wood or laminate floors without a vapor barrier.
