What is a Tecsound Acoustic Membrane?
Tecsound is an advanced, viscoelastic soundproofing membrane that combines high mass with flexibility, making it uniquely effective at blocking sound and reducing vibrations. Made from a dense, polymer-based synthetic material, Tecsound offers substantial noise reduction by adding mass to surfaces, effectively controlling both airborne and impact noise. Tecsound 70SY, in particular, is equipped with a self-adhesive backing, simplifying installation while delivering the same top-tier soundproofing as other Tecsound membranes. This material has become a top choice for those seeking an efficient, reliable, and easy-to-install solution to noise control.
How Does Tecsound 70 Self-Adhesive Membrane Work?
Tecsound 70SY works by increasing the mass of surfaces, effectively blocking airborne sound and reducing sound resonance. Its viscoelastic properties absorb and dampen vibrations, creating a barrier that prevents sound from reverberating through rigid surfaces. This damping effect is essential in applications where impact noise and structural vibrations are concerns. The self-adhesive backing allows for easy application to walls, floors, and ceilings, ensuring a consistent bond and reliable performance. When combined with other materials, like plasterboard or acoustic mineral wool, Tecsound 70SY forms a mass-spring system that further enhances its noise reduction capabilities.
What Type of Noise Does Tecsound 70 Self-Adhesive Membrane Stop?
Tecsound 70SY is designed to block both airborne noise (such as voices, music, and other environmental sounds) and impact noise (like footsteps and vibrations from movement). Its dense, flexible composition allows it to absorb and dampen vibrations, making it particularly effective for applications where resonance needs to be minimised. This versatility allows Tecsound 70SY to manage multiple types of noise effectively, providing a comprehensive solution for controlling sound transmission and vibration.
Where Can the Tecsound 70 Self-Adhesive Membrane Be Used?
This self-adhesive membrane is suitable for use on walls, floors, and ceilings. It’s particularly effective on floors, where its added density enhances impact noise reduction, making it ideal for multi-story buildings, offices, and high-traffic areas. Tecsound 70SY can also be integrated into soundproofing systems alongside materials like acoustic mineral wool, resilient bars, and plasterboard to create high-performance barriers against noise and vibration. Additionally, it’s suitable for specialised uses, such as soundproofing machinery rooms, industrial spaces, and vehicles.

What thickness of Tecsound should I choose for my project?
The ideal thickness of Tecsound depends on the level of noise control required and the type of sound you want to block. For typical residential and commercial spaces, Tecsound 50 (5kg per square metre) provides effective insulation for walls, floors, and ceilings, offering reliable protection against moderate airborne noise. Tecsound 70 (7kg per square metre) is well-suited for floors or areas where additional impact noise reduction is important. In environments needing maximum soundproofing, like studios or industrial settings, Tecsound 100 (10kg per square metre) delivers the highest density for top-tier noise control. When in doubt, a soundproofing professional can help determine the best thickness to meet your project’s specific requirements.
What other materials pair well with Tecsound for improved performance?
Tecsound pairs excellently with a variety of other soundproofing materials to create a more robust noise reduction system. When used with acoustic mineral wool, it creates a “mass-spring” effect that significantly enhances soundproofing, especially for airborne noise. Resilient bars are also a popular addition, as they decouple Tecsound from rigid structures, further reducing vibration transfer and impact noise. For wall and ceiling applications, double-layer plasterboard or acoustic panels can add an extra layer of density and improve overall sound attenuation. Combining Tecsound with these materials creates a highly effective soundproofing system suitable for demanding environments like recording studios, multi-residential buildings, and office spaces.
Using an Under Floor Heating System?
Tecsound 70SY has a thermal conductivity of 0.45 W/mK. Check with your underfloor heating system manufacturer to ensure compatibility, as some heating systems may have specific requirements when used alongside soundproofing materials.
Upgrade Your Soundproofing System with Tecsound
To enhance soundproofing performance, Tecsound 70SY can be layered with other materials, such as Tecsound 50SY or acoustic mineral wool, creating a multi-layered system with additional density. This approach improves soundproofing efficiency across various noise types. Tecsound 70SY also works well with resilient bars and plasterboard, creating a compact, high-performance solution for spaces where noise reduction is essential. Whether for residential, commercial, or industrial applications, Tecsound 70SY elevates soundproofing to a professional standard.
