What Cellofoam does

Cellofoam International GmbH & Co. KG is a German specialty manufacturer of technical and industrial acoustic and thermal insulation products, founded circa 1960 and headquartered in Ochsenhausen/Biberach an der Riss, Germany. The company develops and produces assembly-ready, acoustically optimized components from flexible foams, heavy films (Schwerfolien), and nonwoven fabrics, with applications spanning rail vehicles, buses and commercial vehicles, construction and agricultural machinery, HVAC, heat pumps, cabins and enclosures, mechanical engineering, medical technology, motorboats/yachts, room acoustics, and household appliances. Cellofoam operates three production facilities (Ochsenhausen DE, Tábor CZ, Eskişehir TR), two dedicated sales subsidiaries (Wrocław PL, Saint-Herblain FR), and an authorized distributor network across Australia, China, Denmark, UK, Canada, Spain/Portugal, Switzerland, and South Korea.

The company's core technology is the proprietary Cello® foam finishing process, supplemented by flame-bonding (Flammklebekaschierung) and thermal adhesive bonding (Thermoklebekaschierung) to produce customer-specific acoustic and thermal composite materials. Product categories include Schallschutz (soundproofing), Klebebänder (adhesive tapes), Kaschierung (lamination), Rohrisolierung (pipe insulation), Vliesverformung (nonwoven forming), Schwingungsisolierung (vibration isolation), Dichtungen (seals), Wärmeisolierung (thermal insulation), Verdichterhülle (compressor shells), and Verpackungsschaum (packaging foam). Notable certifications include ISO 9001 (held by three German entities), REACH conformity, EN 45545-2 (R21, HL3) for the Cello® S400 rail seating nonwoven, ECE R-118 for bus interior materials, and Ecobalanced status for melamine products. Managing Directors Holger Stehling and Jörg Roellinghoff lead the company.

Cellofoam operates a dual go-to-market: (1) direct B2B field sales via regional sales teams in Germany, Czech Republic, Poland, France, and Turkey, supported by direct quote-based pricing for industrial customers; and (2) B2C and small-business e-commerce through the soniflex.de online shop, targeting homeowners, craftsmen, recording studios, kindergartens, restaurants, and small construction projects. B2B pricing is not publicly disclosed and is handled through direct contact; the soniflex channel sells standardized small-volume SKUs at listed prices. Demand generation is anchored by cellofoam.de with a product finder tool, LinkedIn/Instagram/Vimeo/YouTube presence, Google Ads paid search, and PR-driven news announcements around certifications and milestones.

Direct peers

• Armacell: Global leader in flexible foam-based insulation for industrial equipment, HVAC, transportation, and acoustic applications. Closest functional peer to Cellofoam across acoustic and thermal foam insulation verticals.
• Recticel: European polyurethane and specialty foam manufacturer serving industrial, transportation (including rail and automotive), and acoustic insulation markets — directly overlapping Cellofoam's customer base and product chemistry.
• Adler Pelzer Group: European specialist in acoustic and thermal insulation systems for rail vehicles, buses, and automotive — directly competing with Cellofoam in noise reduction and NVH components for transportation OEMs.
• Trocellen: European polyolefin and elastomer foam specialist serving automotive, rail, and industrial acoustic applications. Comparable niche position to Cellofoam with similar focus on cross-linked foam technologies.

Broad incumbents

• Huntsman Corporation: Global chemical company with MDI-based polyurethane foam systems used in acoustic, thermal, and vibration-damping applications across transportation and construction — a broader-scale alternative supplier to Cellofoam.
• Johns Manville: US-headquartered industrial insulation manufacturer (Berkshire Hathaway-owned) producing acoustic, thermal, and HVAC insulation products across building, industrial, and transportation segments — broader portfolio scale than Cellofoam.
• Autoneum: Swiss automotive acoustics specialist producing textile and foam-based sound insulation for vehicle interiors. While more automotive-skewed, the technology stack and customer overlap with Cellofoam's rail/bus/heavy-vehicle business are material.
• Sika: Swiss specialty chemicals/construction materials company with acoustic and vibration-damping product lines targeted at transportation and infrastructure — overlapping Cellofoam's rail/HVAC/heavy-vehicle applications at broader portfolio scale.
• BASF (Basotect / Performance Materials): BASF's Basotect melamine foam is a direct material substitute in acoustic absorption and overlaps with Cellofoam's Ecobalanced melamine foam line. As a global chemical major, BASF dwarfs Cellofoam's scale and R&D budget.

Emerging players

• Siderise (Special Products): UK-based acoustic insulation manufacturer focused on construction and industrial noise control. Overlaps with Cellofoam's acoustic product portfolio in industrial and building applications (and is also listed as a Cellofoam UK distribution partner).
