SUSTAINABLE SPRAY-ON INSULATION

The Natural Choice

International Cellulose Corporation is the leading manufacturer of sustainable, spray-on thermal and acoustical finish systems. Consisting of natural, plant-based fibers and specialty water-based adhesives, these products are tailored to meet distinct thermal, acoustical, and design objectives for commercial building projects with an exceptionally low environmental footprint. Cellulose, the primary raw ingredient in our products, contains high levels of sequestered carbon stored within the material for the useful life of the application or building project.

Our products can be used to achieve high thermal R-Values, to help offset operational carbon loads, and provide exceptional acoustical performance to maximize usability and functionality within a space. In addition to acoustic and thermal performance, our products meet some of the world’s most rigorous and comprehensive standards for low emissions of VOCs into indoor air.

MINDFUL MATERIALS
Designed by leaders from across the industry, mindfulMaterials is a platform for sustainable and healthy materials. The Common Materials Framework (CMF) organizes hundreds of factors from relevant product certification and declaration programs into 5 categories of health and environmental performance. Filtering by the CMF enables users to search by sustainability issues, as well as by certification or standard.

MATERIALS & RESOURCES

RECYCLED CONTENT: K-13, SonaSpray “fc”, Ure-K, and SonaKrete are made from 100% recycled cellulose fibers.

REGIONAL MATERIALS: K-13, SonaSpray “fc”, Ure-K, and SonaKrete are manufactured in the United States by International Cellulose Corporation (ICC) in Houston, Texas.

RENEWABLE/RAW INGREDIENTS: Cellulose, the primary raw ingredient in the K-13, SonaSpray “fc”, Ure-K, and SonaKrete spray-on systems contain wood, cotton and other rapidly renewable resources. Cellulose takes less energy to make compared to other building insulation materials and sequesters carbon for the useful life of the application-reducing the release of harmful greenhouse gasses into the environment.

CONSTRUCTION WASTE MANAGEMENT: Cellulose fibers may be fully recovered and reused on-site, leaving virtually no excess material to return to the waste stream.

CRADLE TO CRADLE CERTIFIED®: K-13, SonaSpray “fc”, Ure-K & SonaKrete are Cradle to Cradle Certified® Bronze. (Excludes custom colors.)

HEALTH PRODUCT DECLARATION (HPD): K-13, SonaSpray “fc”, Ure-K, and SonaKrete spray-on systems have been inventoried to 100 PPM in accordance with the Health Product Declaration (HPD).

ENVIRONMENTAL PRODUCT DECLARATIONS (EPD): Product-Specific, third-party verified Environmental Product Declarations (EPDs) to ISO 14025 are available for K-13, SonaSpray “fc”, Ure-K, and SonaKrete. EPDs are published by Sustainable Minds and are available in the Sustainable Minds Transparency Catalog.

INDOOR ENVIRONMENTAL QUALITY (IEQ)

LOW-EMITTING BUILDING MATERIALS: Products are GREENGUARD Gold Certified and M1 Classified as Low Emitting Building Materials.

INDOOR AIR QUALITY: K-13, SonaSpray “fc”, Ure-K, and SonaKrete spray-on systems are GREENGUARD Gold Certified per UL Environmental. GREENGUARD Certification ensures that a product has met some of the world’s most rigorous and comprehensive standards for low emissions of volatile organic compounds (VOCs) into indoor air.

LIGHT REFLECTANCE: Products can be specified to achieve high light reflectance values and to contribute towards daylighting and efficient lighting designs.

Light Reflectance Values (LRV) per ASTM D 2244:

K-13WHITE84+
SONASPRAY FCWHITE86+
SONASPRAY FCARCTIC WHITE89+
SONAKRETEWHITE88+

SonaKrete in Arctic White

CASE STUDY →

Delos’ New York City headquarters, designed with Gensler, demonstrates how workplace design can advance health, wellness, and sustainability, achieving WELL Platinum, LEED Platinum, and Living Building Challenge Petal Certification. To enhance acoustic comfort in the open-plan office, SonaKrete in Arctic White was applied to the ceilings, absorbing excess noise, reducing reverberation, and improving speech intelligibility. Its high light reflectance also maximizes natural daylighting and supports energy efficiency. Together, these benefits contributed to the project’s ambitious performance goals, while SonaKrete’s Cradle to Cradle® Bronze and GREENGUARD Gold certifications supported healthy materials selection and indoor air quality.
