Under-Sreed Impact Sound Insulation

Product catalog summary
Overview: This document provides a detailed guide on Regupol® and Regufoam® under-screed impact sound insulation products, focusing on their technical specifications, performance data, and compliance with noise protection standards. These materials are designed for heavy-duty applications, offering sound insulation and durability under high loads.
Material Specifications: Regupol® and Regufoam® are made from PU-bonded elastomers and mixed-cell polyurethane foam, respectively. They are resistant to moisture, aging, and deformation, with a temperature resistance range from -20°C to +80°C. They are available in rolls and pallets with varying dimensions.
Performance Data: The document provides dynamic rigidity values according to DIN EN 29052-1, with Regupol® sound 47 having the highest rigidity at ≤ 47 MN/m³. Fire classification is Class E (B 2) as per DIN EN ISO 11925-2/DIN EN 13501-1. Maximum traffic loads range from 500 kg/m² to 5,000 kg/m², and impact noise reduction is measured as per ISO 717-2, with values ranging from ∆Lw ≥ 22 dB to ∆Lw ≥ 35 dB.
Testing and Approvals: Impact noise reduction tests were conducted under standard conditions, with specific configurations for concrete floors, insulation mats, and screed thickness. General and European Technical Approvals are noted for each product.
Application Areas: Suitable for production halls, warehouses, supermarkets, concert halls, gyms, residential buildings, and more. Not recommended for areas frequently exposed to moisture, except for specific products.
Benefits: High traffic load capacity, excellent sound insulation performance, low compressibility, negligible creep behavior under continuous loads, easy installation, and long service life. Internal and external quality monitoring ensures product reliability.
Specifications: Designed for high-load environments, offering progressive spring characteristics to minimize joint tearing. Suitable for rooms with heavy-duty floor constructions, such as those used by forklifts. Compressibility range is ≤ 0.8 to ≤ 2.0 mm, withstanding loads up to 30 kN/m².
Noise Protection Standards: DIN 4109 outlines requirements for noise protection, including impact noise. Regupol® and Regufoam® provide effective impact noise insulation, maintaining stability and sound improvement under high loads.
Installation Guidelines: Proper installation involves ensuring the concrete floor is clean and dry, with perimeter insulation strips installed on all adjoining vertical elements. Plates and rolls should be installed butt-joined and taped to prevent acoustic bridges.
Technical Considerations: Emphasizes checking technical specifications and testing impact noise reduction according to EN ISO 140-8. Highlights the need for dynamic rigidity and the potential impact of acoustic bridges on sound insulation effectiveness.
Recommendations: For optimal performance, use products specifically developed for impact sound insulation. Consult with specialist planners for building acoustics to ensure compliance with noise protection standards.
Material Cutting and Installation: Sheet material can be cut to the required length immediately after laying. The material is butt-joined and taped with adhesive tape to prevent acoustic bridges.
Covering with PE Foil: After installation, insulation mats are covered with a PE foil of at least 0.2 mm thickness, taped at the joints to ensure complete coverage and prevent acoustic bridges.
Screed Insulation Types: Various installations are outlined, emphasizing the importance of avoiding acoustic bridges. In conflicts between heat insulation and impact sound dampening, priority is given to sound dampening for health protection.
Installation Methods:
  • Floating Screed: Includes perimeter insulation strips, floating screed, and screed insulation with foil on top.
  • Floating Screed with Underfloor Heating: Similar to floating screed but includes underfloor heating pipes.
  • Under-screed Impact Sound Insulation: Installed on heat insulation with pipelines or under vibrated floors.
References: Lists various buildings worldwide that have utilized Regupol® under-screed impact sound insulation, including notable structures like the Elbphilharmonie in Hamburg and The Shard in London.
Notes: Technical information is subject to manufacturing tolerances and may vary. The most current information is available on the company's website.
