International Cellulose Corporation

What International Cellulose Corporation does

International Cellulose Corporation (ICC) is a Houston, Texas-based industrial manufacturer of spray-applied cellulose thermal and acoustical insulation products, founded in approximately 1963. The company operates a single manufacturing facility at 12315 Robin Blvd in Houston and holds ISO 9001:2015 certification. Its core product portfolio includes K-13 (the flagship spray-applied thermal and acoustical insulation, R-3.7 per inch, Class 1 Class A fire rating), SonaSpray 'fc' (refined-texture exposed ceiling acoustic finish with bond strength exceeding 600 psf), SonaKrete (premium plaster-texture acoustic finish for historic and domed ceilings), Ure-K (15-minute thermal barrier over polyurethane foam), Celbar (cavity and attic insulation), Protek-13 (protective coating add-on), and the SonaEFX specialty line (SonaSnow and Sona-Ash for film and television production effects). The underlying technology is a patented water-based adhesive that bonds specially prepared cellulose fibers with natural fire retardants during spray application, with products manufactured using 80% pre-consumer recycled content.

ICC operates through a sales-led, channel-driven go-to-market model rather than direct end-customer sales. Products are manufactured in Houston and shipped to an international network of factory-trained, certified applicators who perform installation for commercial projects. Revenue is generated through one-time product sales (the dominant stream), hardware and equipment sales (parts and specialized application equipment), and a recurring component via the contractor portal for licensed applicators. Pricing is quote-based and not publicly disclosed; specification is driven through architectural firms and contractor relationships. ICC holds an extensive certification stack including UL Classified, Factory Mutual Approved, UL GREENGUARD Gold, LEED v4, CHPS, HPD 2.0, M1, and ASTM E 84 Class 1/Class A fire ratings, which together form a meaningful specification barrier in commercial construction. Selected enterprise customers include Trend Micro, Uber Advanced Technologies Group, Nespresso, Samsung, Mercedes-Benz Financial Services, LKQ Corporation, Insmed, Crayola Experience, UBS Financial Services, and Gensler offices across the US, Canada, the UK, the Netherlands, Belgium, and Russia. In February 2024, Compagnie de Saint-Gobain acquired ICC to expand its sustainable construction portfolio and support its net-zero carbon target by 2050; ICC continues to operate from Houston as a wholly owned subsidiary, with contact channels now hosted on the Saint-Gobain domain.

Product overview

International Cellulose Corporation offers a comprehensive portfolio of spray-applied thermal and acoustical insulation products for commercial and residential applications. The core product line includes K-13 Thermal Insulation as the flagship spray-applied thermal and acoustical finish, complemented by the K-13 High-R System for high-build applications requiring enhanced R-values. Ure-K provides 15-minute thermal barrier protection over polyurethane foam, while Celbar offers wall cavity and attic insulation. SonaSpray fc delivers exposed ceiling acoustical control with refined texture, and SonaKrete provides premium plaster-texture acoustic finishes for aesthetic-sensitive projects. Protek-13 serves as a protective coating add-on for fibrous insulation. The specialty SonaEFX line includes SonaSnow for film production and Sona-Ash for cinematic effects. All products are manufactured in Houston, Texas using 80% pre-consumer recycled cellulose content with natural fire retardants.
