SONOTIZ AT — Multilayer Acoustic and Thermal Insulation Mat
Overview
SONOTIZ AT is a high-performance multilayer insulation mat engineered for professional soundproofing and thermal protection. It features a dense SONO-ECO fiberglass core wrapped in non-woven spunbond layers for added resilience, decoupling, and durability. The mat delivers excellent performance in reducing impact sound, airborne noise, and heat transfer — making it ideal for floors, walls, ceilings, and complex architectural spaces. Manufactured without binders, the fiberglass mat maintains integrity at temperatures up to 650°C and achieves a non-combustible fire classification A2:s1,d0 under EN 13501-1 standards.
Key Benefits
- Impact Noise Reduction: Up to –24 dB, measured per DIN EN ISO 10140-1 to 5:2021-09
- Fire Rating: A2:s1,d0 (non-combustible, low smoke)
- Fire Rating: A2:s1,d0 (non-combustible, low smoke)
- Decoupling Layer: Prevents cracking in tiles and screeds due to structural movement
- Robust Composition: Resistant to pressure, vibration, and long-term wear
Structure and Materials
SONOTIZ AT is constructed from:
- Core: High-density E-glass fiberglass (SONO Eco)
- Top/Bottom Layers: Aluminized or spunbond non-woven protection
- Assembly: Mechanically pressed without binders or adhesives
This combination ensures excellent sound absorption, vibration damping, and structural resilience.
Applications
SONOTIZ AT is suitable for:
- Recording studios, home theaters, public cinemas
- Wall, floor, and ceiling insulation in residential and commercial buildings
- Apartments, hotels, and acoustic renovation projects
- Mechanical rooms, HVAC installations, and industrial settings
- Under screed systems as a resilient anti-vibration layer
Installation Guide
Under screed use:
Under screed use:
1.
Clean the surface from debris and dust.
2.
Lay SONOTIZ AT mats lengthwise across the area.
3.
Add a 5 cm wall extension margin based on screed height.
4.
Overlap adjacent mats by 5 cm to ensure continuous coverage.
5.
Pour screed at minimum 50 mm thickness or 80 kg/m².
6.
After leveling, trim excess edges and seal perimeter.
Wall & ceiling use:
- Insert as a decoupling or damping layer within drywall or acoustic assemblies.
- Suitable behind gypsum, under acoustic panels, or in cavity partitions.
