ICC's line of spray-applied systems, consisting of natural, plant-based fibers and specialty, water-based adhesives, are carbon-storing materials that contain over 50% recycled content. Cellulose, the primary raw ingredient, has an exceptional embodied carbon profile and contains wood, cotton, hemp and other rapidly renewable resources. During their useful life, these raw material ingredients sequester carbon reducing the amount of harmful greenhouse gasses in the atmosphere. Cellulose takes less energy to make compared to other building insulation materials.

K-13, SonaSpray, Ure-K, and SonaKrete spray-on systems are M1 Classified as Low Emitting Building Material and are compliant with CDPH/CA Section 01350. They are also GREENGUARD Gold Certified per UL Environmental which ensures that a product has met the most rigorous and comprehensive standards for low emissions of volatile organic compounds (VOCs) into indoor air.

ICC products have met the Living Building Challenge requirement that they do not contain chemicals on the Red List. The Red List contains some of the worst materials prevalent in the building industry; for transparency purposes, ICC has provided an ingredient list for 98% of the total product and all proprietary material chemicals have been disclosed to third party to verify they are non-hazardous. K-13, SonaSpray, Ure-K, and SonaKrete spray-on systems are free of heavy metals such as Lead (Pb), Cadmium (Cd), Mercury (Hg), and Hexavalent Chromium (Cr(VI)) or other metals. Furthermore, there are no ozone depleting substances such as CFC’s/HCFCs, Isocyanate or any Brominated Flame Retardants (PBTs).

K-13, SonaSpray, Ure-K, and SonaKrete are manufactured in the United States under the ISO 9001:2015 Quality Management System by International Cellulose Corporation in Houston Texas. Adhesives are produced and shipped in concentrated forms and are diluted with water sourced from the job site. Local sourcing and manufacturing allow for a reduction in transportation costs and emissions.

International Cellulose Corporation’s thermal and acoustical finish systems are spray-applied to common substrates through specialized equipment using approved application techniques. ICC's products are installed by a network of licensed applicators, trained by ICC and supported by their field services team. During the installation, fibers and adhesives are combined forming a durable, monolithic coating over the substrate.

Little to no waste is generated in the installation process.
