Sound insulation materials
Noise control and sound insulation are not just a way to make machine and equipment noise more bearable. They are an effective and necessary contribution to quality of life, people's health and environmental protection: constant noise harms health and well-being, so it is worth controlling both at work and at home.
Why choose these materials
Noise reduction, sound and thermal insulation materials for rooms, vehicles and industrial equipment – selected for your task.
Sound insulation or sound absorption?
This is the most common question when choosing a material. The answer determines which material you need.
Sound insulation
Goal: stop noise travelling to another room or escaping from equipment.
Materials: heavy, dense layers, often combined with foams.
Examples: compressor and pump enclosures, machine cabs, doors.
Sound absorption
Goal: reduce echo and the noise level within the room itself.
Materials: open-cell foams and polyester nonwoven panels.
Examples: offices, meeting rooms, kindergartens, restaurants.
Where it is used
Offices and meeting rooms
Shortens reverberation so conversations and calls are clearer and work is calmer.
Kindergartens, schools, restaurants
Lowers the overall noise level in busy rooms.
Construction and agricultural machinery
Insulation of cabs, engine compartments and hoods for excavators, loaders and tractors.
Heating, ventilation, air conditioning
Acoustic and thermal insulation of heat pumps, compressors and ventilation units.
Mechanical engineering
Enclosures, encapsulation, vibration damping – from single parts to series production.
Buses, rail, boats
Materials for vehicles that meet their fire safety requirements.
Room acoustics solutions
Wall absorbers
soni COLOR (1000 × 500 mm, 8 colours) and soni COLOR Deluxe with an aluminium frame. Glued or fixed with Velcro strips.
Ceiling tiles
soni COLOR RD and soni COMFORT SD (620 × 620 mm) – fit standard grid or OWA ceilings.
Hanging baffles
For large halls, sports and production spaces where wall and ceiling area is not enough.
Desk and room dividers
Separate workstations in open-plan offices and absorb sound.
Acoustic pictures
soni PICTURE – a picture and a sound absorber in one.
Door insulation
soni PORTA – fixed to the door, removable when needed.
“soni COLOR” sound absorbing panels are made of white polyester nonwoven laminated with a subtly marbled felt surface in a choice of 8 colours. Panel size: 1000 × 500 mm. They can be glued directly to the wall or fixed with Velcro strips.
“soni COLOR Deluxe” consists of an elegant high-quality aluminium frame, a sound-absorbing layer of white polyester nonwoven and a felt cover in a choice of 8 contemporary colours. This makes soni COLOR Deluxe not only an effective sound absorber but also a distinctive wall design element that gives rooms a stylish, modern look.
“soni COLOR RD” sound absorbing tiles are made of white polyester nonwoven laminated with a subtly marbled felt surface in many colours. The standard 620 × 620 mm tiles drop easily into existing standard grid or Odenwald (OWA) ceilings.
“soni COLOR Design” – distinctive, colourful design tiles (618 × 618 mm) that fit easily into existing standard grid or Odenwald (OWA) ceilings. They absorb sound and become a striking ceiling feature.
“soni COMFORT SD” acoustic elements are made of highly sound-absorbing polyester nonwoven. The square 620 × 620 mm tiles are designed for suspended standard grid or Odenwald (OWA) ceilings. The thermally compacted face gives a smooth, attractive finish. soni COMFORT SD effectively reduces reverberation and improves acoustics in offices, conference rooms, waiting areas and other spaces.
“soni ROOM DIVIDER” room dividers and “soni DESK PARTITION” desk screens are special sound absorbers: they not only reduce noise but also give staff more privacy. The core is a soft nonwoven board reinforced on both sides with compacted polyester nonwoven. Visible surfaces have a decorative, high-quality, dirt-resistant felt finish, and rounded top corners give a modern look.
“soni PICTURE” – a range of elegant high-quality aluminium-framed wall pictures. Sound is absorbed by white polyester nonwoven invisibly fitted into the tension frame behind the printed fabric. The printed fabric can be replaced at any time. So soni PICTURE not only improves room acoustics but also decorates the interior.
“soni ELEMENT” – a range of decorative acoustic elements that absorb noise effectively. They are made of white polyester nonwoven, optionally laminated with a decorative felt surface (8 contemporary colours). soni ELEMENT lowers noise levels and improves acoustics, making spaces quieter and more pleasant – especially day centres, kindergartens, schools and cafés.
“soni CUBE” seating cubes are distinctive sound absorbers: they improve room acoustics and double as a comfortable seat. The outer cover is made of dirt-, abrasion- and flame-resistant felt. If needed, a metal spiral can be screwed into one corner so the soni CUBE hangs from the ceiling on a cord or hook – a simple and effective way to install it.
“soni PORTA” kit consists of six precisely matched elements that form an eye-catching pattern and are glued directly onto the door – improving its sound insulation and damping. Shadow joints give the pattern depth, turning any door into a decorative interior feature. Thanks to the new self-adhesive surface, soni PORTA elements can be removed without leaving any residue.
“soni PYRAMIDE” – a pyramid-profile material made of open-cell melamine foam (Basotect®) that reduces noise very effectively. It offers excellent sound absorption and an attractive surface pattern. soni PYRAMIDE meets building-sector fire safety requirements, so it is suitable wherever noise must be reduced with materials that meet strict fire regulations.
Constant noise makes it hard to concentrate at work and increases the risk of accidents, so workplace safety rules require noise levels to be reduced as far as possible. Acoustic products such as “soni WAVE” – robust, dirt-resistant PUR foam with excellent sound absorption – are ideal for this.
Every machine, large or small, makes noise that can be very tiring. The most effective way to reduce it is to place the machine in a sound-insulating enclosure. Robust PUR foams “soni WAVE” and “soni 471Ä” are ideal for such enclosures. For machines outdoors, the best choice is “soni RESIST”: weather-resistant PE foam with both sound insulation and sound absorption properties.

Frequently asked questions
What is the difference between sound insulation and sound absorption?
Insulation stops sound passing through a wall, enclosure or door – this needs heavy, dense materials. Absorption reduces echo within the room – this uses porous materials (foams, nonwovens). The best result often comes from combining both.
How are absorbers installed?
Wall panels are glued directly to the wall (e.g. with spray adhesive) or fixed with Velcro strips. 620 × 620 mm ceiling tiles fit standard grid ceilings, and baffles are suspended from the ceiling.
Are the materials fire resistant?
Many Cellofoam materials are tested to EN 13501, EN 45545-2 (rail) or ECE R-118 (buses). We state the class of the specific material in our quote and provide the documents.
Can parts be made to a drawing?
Yes. For technical applications (enclosures, cabs, equipment) materials are cut and shaped to a drawing or sample. Send the drawing or dimensions via the enquiry form.
How many absorbers does my room need?
It depends on the size of the room, its surfaces and use. Send us the room dimensions, its use and photos if you have them – we will calculate the quantity and suggest a solution.
Are quality and compliance documents available?
Yes – the manufacturer's ISO 9001 certificate and REACH and RoHS declarations of conformity. You will find them on this page under 'Quality and compliance documents'.
If you can't find the product you need, describe how it will be used and send a drawing or photo. We will help you choose – and if there is nothing suitable, have it made. Fill in the enquiry form and we will help you!
