Storage
SONOTIZ BLOCK panels must be stored in a dry, well-ventilated environment, protected from high humidity, condensation, or direct exposure to moisture. Therefore, they cannot be stored and installed in a room with high humidity.
Before installation, panels should be stored for at least 24 hours in the same environment where they will be installed. This acclimatization period allows the panels to adjust to ambient temperature and humidity, ensuring optimal sound insulation and dimensional stability.
To prevent warping or bending, panels must be stored and transported horizontally on a flat surface. By following these storage and handling guidelines, users can maintain the full performance, durability, and longevity of SONOTIZ BLOCK panels.
General Overview
SONOTIZ BLOCK is a high-density acoustic insulation panel engineered to deliver powerful soundproofing in a compact format.
Manufactured from wood fiber with a corrugated structure and filled with calcined quartz filler, it combines the essential acoustic principles of mass, elasticity, and multi-layer absorption. This combination of materials and design ensures effective damping of sound waves of various frequencies.
This innovative design makes SONOTIZ BLOCK ideal for walls, ceilings, and floors, providing effective reduction of airborne and impact noise in residential, commercial, and industrial spaces — without increasing wall thickness.
How It Works
SONOBLOCK’s performance is based on a triple-action structure:
1.
Mass: the quartz sand filler acts as a dense barrier, absorbing and dissipating sound wave energy.
2.
Elasticity: the flexible wood-fiber framework absorbs vibrations and prevents sound propagation.
3.
Multi-layer dissipation: alternating layers of different densities cause partial energy loss when sound waves pass between materials.
Key Benefits

FAQ
What is SONOTIZ BLOCK and what problem does it solve?
SONOTIZ BLOCK is a high-performance multilayer acoustic insulation panel designed to reduce airborne noise, impact noise, and structure-borne vibrations in walls, ceilings, and floors.
It is engineered for situations where maximum sound insulation is required with minimal system thickness, making it especially suitable for apartments, offices, hotels, studios, modular constructions, and renovation projects.
What types of noise does SONOTIZ BLOCK reduce?
SONOTIZ BLOCK addresses three main noise mechanisms:
1. Airborne noise
(speech, TV, music, traffic, neighbors)
2. Impact noise
(footsteps, dropped objects, mechanical impacts)
3. Structural / vibration noise
(noise transmitted through building structures)
The panel works by combining mass, elasticity, and multilayer energy dissipation, which are fundamental principles of modern acoustic engineering.
How does SONOTIZ BLOCK work from a scientific acoustic perspective?
SONOTIZ BLOCK is based on physical acoustic laws, not “sound absorption myths”.
Its performance relies on:
– Mass effect
The calcined quartz core increases surface density, which resists sound wave transmission.
– Elastic damping
The corrugated cellulose structure converts acoustic energy into mechanical losses.
– Multilayer dissipation
Alternating materials with different densities and geometries progressively reduce sound energy across frequencies.
This combination allows effective noise reduction even at 12–18 mm thickness, which is impossible with traditional single-material solutions.
What is the sound reduction performance of SONOTIZ BLOCK?
When installed as part of a complete wall system, SONOTIZ BLOCK achieves up to 58 dB airborne noise reduction, according to laboratory testing.
Important professional note:
Sound insulation values always depend on the entire system, not a single material. Performance is influenced by:
- installation quality
- supporting structures
- flanking paths
- sealing of joints
SONOTIZ provides system-based engineering solutions, not isolated product claims.
Is SONOTIZ BLOCK suitable for DIY installation?
Yes. SONOTIZ BLOCK is suitable for both DIY users and professional installers, provided that installation guidelines are followed.
Key DIY-critical rules:
- full-surface adhesive contact (no spot gluing)
- airtight joint sealing
- elimination of air gaps and sound bridges
Improper installation can reduce acoustic performance significantly, regardless of material quality.
Can SONOTIZ BLOCK be combined with products from other manufacturers?
Yes, professionals sometimes integrate SONOTIZ BLOCK into custom acoustic systems.
However, an important technical clarification:
- Sonotiz performance recommendations apply only to systems officially developed and tested by the Sonotiz engineering team.
Custom combinations may work, but acoustic results cannot be guaranteed outside validated system designs.
Why does soundproofing often fail even with “good materials”?
From an engineering perspective, soundproofing fails due to:
- air gaps and unsealed joints
- rigid mechanical connections (sound bridges)
- incorrect layer sequence
- misunderstanding of noise type (airborne vs impact vs vibration)
SONOTIZ BLOCK is designed to be part of a system approach, not a “magic panel”.
Who is SONOTIZ BLOCK designed for?
SONOTIZ BLOCK is engineered for:
- DIY users seeking professional-grade results
- installers and contractors
- acoustic consultants and architects
- distributors and wholesale buyers
The product bridges the gap between scientific acoustics and real-world construction practice.
