Acoustic foams and acoustic fleeces from BOSIG

Q: What is the difference between sound insulation and sound absorption?

Sound absorption reduces reverberation and echo formation within a room.Sound insulation (vibration damping, sound decoupling, anti-drumming) prevents sound from being transmitted from one room to another.Sound separation: acoustic separation of different areas with distinct acoustic requirements within a single space (open-plan, modern room concepts).

Acoustic foams and acoustic fleeces form the foundation for modern and effective room acoustics and sound insulation solutions in public, industrial and private environments.

BOSIG offers you a wide range of high-quality acoustic foams, specially developed

for optimising room acoustics in public spaces and industrial halls,
for improving speech intelligibility in offices, call centres, schools, nurseries, cafés, restaurants and even private living rooms, as well as
for reducing vibrations and precisely adjusting reverberation times

through their sound-insulating and sound-absorbing properties.

Whether in offices, public buildings, production halls or private spaces – our acoustic products ensure a noticeably more pleasant sound environment.

BOSIG Product Range in Acoustic Foams

Our portfolio includes various product lines such as:

Noiseflex® MH made of Basotect® melamine resin foam – a lightweight, efficient sound absorber in visually appealing colours (white, grey, black) with high temperature resistance. The Basotect® acoustic foam often meets the most stringent fire protection requirements (fire protection class B1 according to DIN 4102 – flame-retardant).
Noiseflex® PU made of polyurethane foam – versatile for use on walls, ceilings or machine enclosures: the cost-effective classic.
Noiseflex® Conso PET acoustic absorber – made from recycled materials, durable and sustainable: PET provides good compressive strength and sound absorption at a medium density.
Noiseflex® VB (composite foam) – available in various versions with high density, offering excellent sound absorption in the low-frequency range and a high recycled content.
Polyethylene foams such as Microlen, Hydro or Noiseflex® Piano and Noiseflex® Vallo: robust, water-repellent foams for decoupling and sound absorption depending on pore structure.

Properties of Modern Acoustic Foams

Modern acoustic foams are versatile, customisable and offer a variety of material and surface options to provide targeted design solutions for a wide range of acoustic challenges. Both the acoustic and visual aspects are equally important to meet today’s demands for harmonious interior design.

Acoustic foams offer, among others:

High sound absorption (particularly in the speech frequency range)
Depending on the type, also thermal insulation properties
Resistance to moisture, chemicals or ageing – especially with materials such as melamine resin or EPDM (cellular rubber)
Combination options: the combination of different acoustic foams in sandwich construction enables optimal acoustic solutions for the highest demands
Numerous refinement options for durable, easy-to-clean, protected surfaces or self-adhesive versions for easy on-site installation
Compliance with specific standards such as fire protection (flame-retardant, B1 classification)

Why Choose Acoustic Foams from BOSIG?

Our acoustic foams combine premium material quality with innovative manufacturing technology. They are:

Effective: Excellent sound absorption for optimal acoustics
Flexible: Available in a variety of shapes, cuts and applications
Material Options: Materials with recycled content, advanced material solutions or innovative manufacturing processes, depending on the product line.
Design-oriented: Function meets modern design through high-quality surface finishes, surface designs with image motifs, fabric laminations and a variety of colouring processes

Typical Applications for Acoustic Foams

The possible applications of our acoustic foams are wide-ranging:

Offices, open-plan offices and conference rooms: Reduction of disturbing reverberation times and improvement of speech intelligibility, targeted acoustic shielding of individual workstations or work areas.
Industry, mechanical and vehicle engineering: Noise reduction for loud machinery and processes, sound insulation, engine compartment damping.
Group rooms in nurseries and daycare centres, classrooms in schools & rooms in public buildings: Creation of a pleasant learning and working environment, improvement of speech intelligibility.
Recording and music studios & rehearsal rooms: Optimum acoustics for sound and music production, optimisation of sound quality.
Cinemas, theatres and concert halls: Optimisation of room acoustics through precise adjustment of reverberation time.
Private households: Sound insulation on doors or, for example, washing machine pads (white goods) for vibration and noise damping.

Key Selection Criteria for Acoustic Foams

When choosing the right foam, the key factors are the material, density, pore structure, and additional aspects such as flammability and the desired acoustic properties.

Below are some essential criteria for making the right choice:

Material type: Primarily polyurethane (PU), melamine resin (Basotect®) or composite foams are used.

Pore structure and density: Fine-celled, open-pored foams and fine-pored fleeces absorb sound particularly effectively and are generally very durable. The main factor is the fine-pored structure rather than density alone. Open-pored foams and fine-pored fleeces absorb sound efficiently, making them ideal for use in open-plan offices or conference rooms.

- Egg-crate foam – the classic all-rounder with high sound absorption in the mid and high-frequency range.
- Pyramid foam – for particularly efficient sound diffusion and absorption.
- Fleece lamination – for additional insulation, surface protection and visual enhancement.
- Plain foams – universally usable for design and functional elements, available with chamfered edges.
- PET fleeces in various versions – fully hardened for sound separation, surface-hardened as high-quality wall and ceiling absorbers.
Depending on the application area, the ideal surface structure of the acoustic foam should therefore be selected. BOSIG offers a wide range of structured and smooth surfaces.
Fire protection: In public areas, flame-retardant variants should be used (e.g. melamine resin, PET fleeces); particular attention should be paid to fabric selection when refining base materials.

FAQ on Acoustic Foams

What is the difference between sound insulation and sound absorption?

Sound absorption reduces reverberation and echo formation within a room.

Sound insulation (vibration damping, sound decoupling, anti-drumming) prevents sound from being transmitted from one room to another.

Sound separation: acoustic separation of different areas with distinct acoustic requirements within a single space (open-plan, modern room concepts).

Which acoustic foams are best suited for studios?

Pyramid foam Noiseflex® Pyramis and egg-crate foam Noiseflex® La Ola are ideal, as they significantly reduce sound reflections.

Which acoustic solutions are suitable for offices?

Noiseflex® Partition Wall L and Noiseflex® Partition Wall S for sound separation.

Wall and ceiling absorbers or ceiling baffles made from melamine resin foam or PET fleece, such as Noiseflex® Cover, Noiseflex® Conso Panel, Noiseflex® Picture and Noiseflex® Nature.

Which acoustic solutions are ideal for schools and nurseries?

Baffle systems such as Noiseflex® Cube and Noiseflex® Corpo offer excellent acoustic properties and extensive design possibilities thanks to a wide range of cover fabrics and the option of custom motif printing.

Are acoustic solutions with recycled content or advanced material solutions available?

Yes, BOSIG offers acoustic solutions containing recycled content as well as selected materials with a reduced Product Carbon Footprint (PCF). These include, for example, PET-based foams containing recycled material and selected melamine foam variants. Further information can be found in the respective product data sheets.

Can acoustic foams be retrofitted?

Yes, our products are flexible in use and can be retrofitted to walls, ceilings or machinery.

Are BOSIG acoustic foams and acoustic fleeces PFAS- and pollutant-free?
