Soundproofing 3mm 1x10m Damtec Multi KRAIBURG

DAMTEC Multi is an elastic soundproofing membrane made of pressed SBR rubber granulate bonded with polyurethane elastomer. The material is homogeneous, elastic and resistant to long-term mechanical loads, ensuring stable acoustic and mechanical characteristics throughout the entire service life of the structure.

With a bulk density of approximately 1020 kg/m³ and a compressive strength of up to 5000 kPa, the membrane functions as an elastic separation layer that limits the transmission of impact, airborne and structure-borne noise between the building's structural elements.

Application area

DAMTEC Multi is used as an acoustic separation and damping layer in the following construction systems:

• Under cement and floating screeds
• Under final floor coverings (parquet, laminate, ceramic flooring, etc.)
• Behind and between plasterboard or other cladding panels on walls and ceilings
• As a dividing strip under brick walls
• Between double walls to break the acoustic bridge

Main advantages

• Effectively reduces impact and airborne noise in building structures
• Limits the transmission of structure-borne noise and vibrations between structural elements
• Suitable for underfloor heating systems, thanks to its good thermal conductivity and diffusion-open structure
• High acoustic efficiency at minimal thickness, making it suitable for systems with limited structural height
• Long-lasting elasticity and mechanical stability under constant loads

Technical characteristics

• Density: ~1020 kg/m³
• Compressive strength: up to 5000 kPa
• Elongation at break: ~50%
• Operating temperature range: -30°C to +80°C
