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.
