Tecsound 50SY Self-Adhesive Membrane

Tecsound 50SY Self-Adhesive Membrane is a highly effective, market-leading acoustic membrane that provides exceptional soundproofing for walls, floors, and ceilings. Known for its flexibility, durability, and ease of use, this self-adhesive membrane is engineered to reduce both airborne and impact noise, making it ideal for residential, commercial, and industrial spaces. Its high density, combined with its convenient self-adhesive backing, makes installation straightforward and creates a powerful barrier against unwanted noise and vibrations.

What is a Tecsound Acoustic Membrane?

Tecsound is a cutting-edge, viscoelastic soundproofing membrane specially crafted to offer exceptional acoustic insulation. Unlike conventional, rigid soundproofing materials, Tecsound combines significant density with a unique flexibility that enables it to effectively absorb and block a wide range of noises. Engineered with a high-density, polymer-based structure, Tecsound provides sound-blocking capabilities comparable to that of lead but without the associated bulk or toxicity. The innovative material can adapt to any surface, providing a soundproofing solution that maintains space efficiency while creating a quieter, more peaceful environment. The self-adhesive Tecsound 50SY brings this advanced soundproofing to an even more accessible level, allowing for easy, direct application on various surfaces, making it suitable for diverse soundproofing projects.

How Does Tecsound 50SY Self-Adhesive Membrane Work?

Tecsound 50SY functions by significantly increasing the mass on treated surfaces, effectively reducing the transmission of airborne sounds while minimising sound resonance. The viscoelastic properties of Tecsound allow it to dampen vibrations, transforming sound energy into less disruptive forms and preventing it from traveling through walls, floors, and ceilings. This damping effect, combined with the convenience of its self-adhesive backing, allows Tecsound 50SY to bond tightly to surfaces, forming a continuous, robust soundproofing layer. For even more comprehensive sound control, Tecsound 50SY can be combined with other soundproofing materials, such as acoustic mineral wool, creating a “mass-spring” effect that enhances its ability to block noise and absorb vibrations. This makes it a versatile choice for multi-layered soundproofing systems in high-demand environments.

What Type of Noise Does Tecsound 50SY Self-Adhesive Membrane Stop?

Tecsound 50SY is engineered to address multiple types of noise, offering effective insulation against both airborne sounds—such as conversations, music, and ambient noise—and impact sounds from sources like footsteps, dropped items, or furniture movement. Thanks to its dense construction and viscoelastic composition, Tecsound 50SY is also highly effective at dampening vibrations, making it particularly beneficial in settings where metal or other rigid surfaces might amplify noise. This adaptability makes Tecsound 50SY ideal for applications that require comprehensive sound management, ensuring reduced sound transmission across various frequencies and noise types.

Where Can the Tecsound 50SY Self-Adhesive Membrane Be Used?

Tecsound 50SY is an incredibly adaptable membrane, designed for use on walls, floors, and ceilings, allowing it to suit a broad range of environments. It’s an ideal choice for residential spaces, commercial properties, music studios, and other environments where controlling noise levels is critical. Tecsound 50SY also excels in more specialised applications, such as soundproofing vehicles, machinery rooms, and HVAC systems. In these cases, it dampens vibrations and reduces noise radiated by engines and metal structures, making it a versatile choice for both traditional and unique soundproofing needs.

How to Install the Tecsound 50SY Self-Adhesive Membrane

1. Prepare the Surface: Ensure the surface is clean, dry, and smooth. Any dust, debris, or loose materials should be removed for a secure bond.
2. Apply the Membrane: Simply peel back the protective layer on the self-adhesive side and press Tecsound 50SY onto the surface. For floors, ensure the reinforcing scrim is facing up, and for walls, the scrim should face outward.
3. Seal and Overlap: Overlap the edges of each sheet slightly and use acoustic tape to secure seams, creating a continuous barrier. For even greater soundproofing, apply a finish layer such as plasterboard or additional flooring material over the Tecsound membrane.

What Are the Benefits of the Tecsound 50SY Self-Adhesive Membrane?

• Exceptional Noise Reduction: Effectively blocks both airborne and impact noise, creating a quieter environment.
• Self-Adhesive Backing: Simple to install, allowing for quick application and a strong bond to surfaces.
• High Density with Flexibility: Delivers substantial soundproofing without adding excessive bulk or thickness.
• Fire Resistant and Safe: Made from high-quality, non-toxic materials, including an asphalt-free and PVC-free formula.
• Versatile Applications: Suitable for a range of surfaces and settings, from walls to ceilings and even vibrating surfaces.

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.
