High-density, polymer-based, asphalt-free synthetic membrane for excellent sound insulation
TECSOUND® is a high-density, viscoelastic synthetic soundproofing membrane designed to provide excellent acoustic protection across various building elements—walls, floors, ceilings, roofs, and industrial applications. Unlike traditional sound insulation materials, TECSOUND® achieves high soundproofing performance without increasing the system’s thickness, making it ideal for modern projects where space and flexibility are key.
Product | Thickness | Weight | Dimensions | System Rw* |
TECSOUND 35 | 1.75 mm | 3.5 kg/m² | 8 m x 1.22 m | Rw to 34 dB |
TECSOUND 50 | 2.5 mm | 5 kg/m² | 6 m x 1.22 m | Rw to 43 dB |
TECSOUND 70 | 3.5 mm | 7 kg/m² | 5 m x 1.22 m | Rw to 46 dB |
TECSOUND 100 | 5 mm | 10 kg/m² | 4 m x 1.20 m | Rw to 53 dB |
*The values are for the complete system (according to the manufacturer’s technical data sheet), not for the membrane on its own.
TECSOUND® uses high viscoelasticity as a sound barrier, significantly reducing noise from air, rain, and vibrations. When combined with absorptive materials such as mineral wool, it creates a mass-spring effect that maximizes energy dissipation.
TECSOUND® is used in major projects around the world—airports, sports halls, convention centers, and commercial buildings—providing proven acoustic comfort and performance.
