Roll resilient underlay BUILDMAT

recycled rubberSBRinsulated

Overview
BEKA BUILDMAT is a recycled SBR rubber roll for acoustic, thermal and vibration insulation in building systems (nominal density 820 kg/m³). The roll format enables fast and efficient installation across large surfaces and adapts to concrete floor systems, floating floors, partitions and concrete sandwich structures.

Key benefits

• Acoustic insulation: reduces transmission of impact noise and structure-borne vibrations.
• Vibration dampening: elastic rubber structure mitigates structural vibrations.
• Thermal insulation: contributes to improved thermal resistance and reduced thermal bridges.
• Durability and sustainability: manufactured from recycled SBR rubber granules to preserve mechanical and insulating properties over time.
• Easy installation: roll format suitable for installation beneath screeds, inside wall systems and within concrete sandwich constructions.

Applications

• Integration within concrete floor systems and floating floors.
• Partition walls and lightweight construction assemblies.
• Installed beneath screeds, inside wall systems or within concrete sandwich structures to create a continuous insulating layer.

Material

• Recycled SBR rubber granules.
• Non-porous surface.
