What thickness of Tecsound should I choose for my project?

The best Tecsound thickness for your project depends on the required noise reduction and the type of sound being blocked. Tecsound 50 (5kg per square metre) is an excellent choice for general soundproofing in homes and offices, providing effective control over moderate airborne noise on walls, floors, and ceilings. For enhanced impact noise reduction, especially on floors, Tecsound 70 (7kg per square metre) offers increased density. In environments demanding top-tier soundproofing, like studios or industrial areas, Tecsound 100 (10kg per square metre) delivers the highest level of insulation. If you’re uncertain, consulting a soundproofing professional can ensure the right fit for your project’s specific needs.

How does Tecsound compare to other soundproofing materials?

Tecsound stands out from traditional soundproofing materials due to its unique combination of high density, flexibility, and viscoelastic properties. Unlike rigid materials like plasterboard or conventional mass-loaded vinyl, Tecsound’s flexible polymer composition allows it to absorb and dissipate vibrations effectively, creating a “damping” effect that prevents noise from resonating through surfaces. Additionally, Tecsound achieves sound insulation levels comparable to lead without the associated toxicity or bulk, making it a safer, space-efficient solution. This versatility allows it to tackle both airborne and impact noise with exceptional effectiveness, making it ideal for a wide range of applications, from residential walls and floors to demanding industrial settings.

Using an Under Floor Heating System?

The Tecsound 50SY membrane has a thermal conductivity of 0.45 W/mK. Before installing it over underfloor heating, check with the system manufacturer to ensure compatibility, as some systems may have specific requirements for use with soundproofing materials.

Upgrade Your Soundproofing System with Tecsound

To achieve maximum noise reduction, Tecsound 50SY can be layered with other soundproofing materials, such as Tecsound 70 or acoustic mineral wool, creating a powerful multi-layered system. Adding layers enhances both the density and resilience of the soundproofing barrier, providing robust protection against a broader range of frequencies. Combining Tecsound with resilient bars or plasterboard further strengthens the sound barrier, absorbing and dampening noise effectively without adding excessive bulk. This layering approach is ideal for creating high-performance soundproofing solutions that fit seamlessly into both small and large spaces, offering professional-grade noise reduction without sacrificing valuable room space. Whether for residential, commercial, or industrial settings, a Tecsound-integrated system is a dependable choice for superior sound control.
