Soundproofing & Thermal Mat for Floors, Walls and Ceilings

Purpose

High-density fiberglass solution made to кeduce impact noise, structure-borne vibrations and heat loss in modern buildings — with one flexible, high-performance material.

Description

SONOTIZ AT is a high-density insulation mat made of pressed E-glass fibers, protected by spunbond layers. It’s engineered to isolate vibration, reduce impact and airborne noise, and improve thermal performance - all in a compact 12 mm profile. The material is non-combustible (Euroclass A2-s1,d0), hydrophobic, VOC-safe and extremely durable. Used for floating screeds, acoustic wall lining or part of multi-layer soundproof systems.

Application

Typical placement:

- Under screed in floating floor systems

- Behind drywall as standalone acoustic lining

- Inside stud walls with mineral wool

- As part of complex soundproofing assemblies (multi-layer systems)

- Technical zones, plant rooms, cinemas, media rooms

Building types:

- Residential apartments and houses

- Commercial spaces (offices, hotels, conference rooms)

- Public buildings (schools, hospitals, administrative)

- Industrial facilities (production halls, machinery enclosures)

- Retrofit and renovation projects

General Overview

SONOTIZ AT is a professional-grade soundproofing and thermal insulation mat, trusted by contractors, architects, and acoustic engineers across Europe. It is widely used in certified multilayer systems for walls, floors, and ceilings - both in new construction and renovation projects.

At the same time, SONOTIZ AT is lightweight, easy to handle, and safe to cut, making it equally suitable for DIY use in home studios, private apartments, or office upgrades. Even first-time users can quickly learn to install it with basic tools and simple guidelines.

Combining technical performance with user-friendly installation, SONOTIZ AT bridges the gap between professional systems and accessible acoustic improvement.

Advantages how it works? Key benefits

How It Works

SONOTIZ AT uses three mechanisms:

Mass Effect: high surface density blocks footfall noise

Elasticity: flexible core dampens vibrations

Multilayer Separation: each layer weakens and reflects sound energy

Combined, this creates a powerful barrier against both airborne and impact noise, while adding thermal insulation and mechanical stability under finishes.

Instalation as part of the Soundproofing System

Wall Soundproofing Systems

Used in:

– SonoFrame Essential

– SonoFrame Advanced

– SonoFrame Pro

In these systems, SONOTIZ AT is applied directly to the wall structure, combined with acoustic hangers, mineral wool, decoupled framing, and multilayer gypsum boards. Ideal for studios, offices, and multi-room separation.

Ceiling Absorption Systems

Integrated in:

– SonoFrame Pro Ceiling

– SonoFrame Essential

– SonoAir Buffer

In ceiling assemblies, SONOTIZ AT improves impact decoupling and airborne noise absorption, reducing transmission between floors in apartments, hotels, or technical ceilings.

Floor Insulation Systems

Installed in:

– SonoFloor Basic

– SonoFloor Pro

In floor setups, SONOTIZ AT is laid under screed to isolate footfall noise and structural vibration. It ensures durable, floating floor performance — with or without additional damping layers.

Recommended Applications

Floating screed floors in apartments, offices, hospitals, schools

Lightweight partitions and wall upgrades in renovations

Studios, theaters, conference and media rooms

Under raised floors, machine bases or building plant rooms

Anywhere sound reduction and fire safety are both required

Instalation

SONOTIZ AT is designed for quick and flexible installation across walls, floors, and ceilings in both residential and commercial buildings.

It can be applied:

Under screed in floating floors to reduce impact noise and vibration

Behind drywall as a standalone acoustic and thermal lining

Inside stud walls or suspended ceilings as part of multi-layer soundproofing systems

Suitable for use in apartments, offices, hotels, cinemas, mechanical rooms, and renovation projects.

Whether you're upgrading a single wall or planning a full soundproofing system, SONOTIZ AT integrates seamlessly with standard construction materials and methods.

Faq

1. What problem does SONOTIZ AT solve?

SONOTIZ AT addresses two common issues in modern buildings: unwanted noise (both impact and airborne) and heat loss. It solves the problem of floor-to-floor footstep noise, wall-to-wall conversation bleed, and vibration transmission in lightweight constructions – while also acting as a thermal barrier.

2. What is SONOTIZ AT and where is it used?

SONOTIZ AT is a non-combustible soundproofing and thermal mat made from pressed E-glass fibers. It is used under screed, behind drywall, and inside acoustic wall or ceiling systems – in homes, offices, hotels, studios, and technical buildings.

3. Who is SONOTIZ AT designed for?

SONOTIZ AT is designed for architects, contractors, and acoustic professionals working on certified construction projects — as well as private homeowners, DIY users, and renovators looking to reduce noise and improve thermal comfort. The product is non-toxic, VOC-safe, and conforms to EU building and fire safety standards, making it safe for use in homes, schools, offices, medical spaces, and public buildings.

4. Can I install SONOTIZ AT myself?

Yes. SONOTIZ AT is DIY-friendly: it’s lightweight, flexible, safe to handle (no itch, no fiber release), and easy to cut with a utility knife. However, we recommend using personal protective equipment (PPE) such as gloves, dust mask, and safety glasses – especially when cutting large areas. Installation requires no special tools, and most users learn quickly from our step-by-step instructions. it’s lightweight, flexible, safe to handle (no itch, no fibers), and easy to cut with a standard utility knife. We provide clear installation instructions and guidance for each application – wall, floor, or ceiling.

5. Is this product suitable for professional systems?

Absolutely. SONOTIZ AT is part of our certified systems such as SonoFrame, SonoFloor, and SonoAir. It is used by acoustic specialists, contractors, and architects in large-scale residential and commercial projects.

6. Can SONOTIZ AT be installed on uneven surfaces?

SONOTIZ AT must be applied to clean, dry, and mostly level surfaces. While it can flex slightly to accommodate minor surface variations, significant unevenness (over 5 mm per 2 meters) should be corrected first to ensure consistent acoustic contact and prevent performance loss.

7. Does SONOTIZ AT help with both impact and airborne noise?

Yes. Under screed, it reduces impact noise by up to 24 dB. In walls or ceiling systems, it contributes to up to 48 dB airborne sound insulation – when combined with gypsum boards and mineral wool.

8. Can I use it in humid or technical spaces?

Yes. SONOTIZ AT is hydrophobic and retains its properties even in damp environments such as basements, bathrooms, or mechanical rooms. It does not absorb water or rot.

9. Is it safe for indoor use?

Yes. SONOTIZ AT is VOC-safe, non-toxic, and made without harmful binders. It is fire-rated A2-s1,d0 (non-combustible) and safe for living spaces, hospitals, or schools.

10. Do you offer bulk pricing or B2B distribution?

Yes. SONOTIZ works with distributors, construction companies, and developers across Europe. To request bulk pricing, technical files or dealer terms, contact our commercial team at [email protected].

11. Can SONOTIZ AT be combined with products from other manufacturers?

Yes, professionals sometimes integrate SONOTIZ AT into custom soundproofing systems using materials such as:

acoustic membranes,

rubber mats,

mineral wool,

OSB boards,

soundproofing compounds,

standard drywall,
or vibration dampers from other brands.

However, an important technical clarification: Sonotiz performance recommendations apply only to systems officially developed and tested by the SONOTIZ engineering team.
