TECSOUND® Soundproofing Membrane

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.

Key Advantages

Exceptional Sound Insulation: TECSOUND® provides high sound insulation across all frequency ranges, effectively blocking airborne noise, impact noise, and vibrations.
Flexible and Adaptable: Highly flexible and easy to install, TECSOUND® adapts to uneven surfaces and complex configurations.
Vapor Barrier: Acts as a vapor-resistant layer, protecting the structure from moisture.
Easy Handling: Lightweight, easy to cut, and adheres well to most surfaces.
Fire Resistance: Euroclass B, s2, d0 rating for enhanced safety.
Durability: Resistant to aging, decay, cold (flexible down to -20°C), and heat.

Applications

Строителен сектор:
- Акустична изолация на вертикални стени (гипсокартон, тухли, бетонни блокове)
- Тавани и подове (включително под замазка, паркет, плаващи подове)
- Метални и дървени покриви (намаляване на шум от дъжд, градушка, вятър)
- Шумоизолация на канализационни тръби и вентилационни отвори

Индустриален сектор:
- Шумоизолация на корпуси на двигатели, компресори, климатични инсталации
- Заглушаване на вибрации в автомобили, автобуси, трактори
- Префабриковани панели, подвижни преградни стени, врати, ролетни кутии

Typical Installations:

Product	Thickness	Weight	Dimensions	Acoustic Insulation*
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

*Rw values depend on the system configuration and installation.

Technology and Installation

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.

Suitable for most construction substrates (drywall, metal, concrete, plastic)
Can be installed using adhesive or mechanical fastening
It is recommended to overlap the joints by 5 cm and ensure proper sealing for optimal acoustic performance.
Acts as a vapor barrier and can be combined with thermal insulation.

Example Applications

TECSOUND® is used in major projects around the world—airports, sports halls, convention centers, and commercial buildings—providing proven acoustic comfort and performance.
