Quick Answer
When shopping for natural insulation products, look for certifications such as Greenguard Gold, Declare Label, or National Organization of Remodeling Industry (NORI) certification. These labels ensure the insulation meets standards for indoor air quality, sustainability, and performance. A reputable certification from a third-party organization provides assurance of the product's quality.
Material-Specific Certifications
Natural insulation products like sheep wool, hemp, and straw often carry certifications specific to their raw materials. For example, the Responsible Wool Standard (RWS) is a label that verifies the wool’s sourcing and treatment. Hemp insulation may carry a certification from the Hemp Industries Association (HIA). These certifications confirm that the manufacturer meets strict guidelines for the production process, ensuring the insulation meets performance and sustainability standards.
Thermal Performance Certifications
When evaluating the thermal performance of natural insulation products, look for certifications from organizations like the International Organization for Standardization (ISO) or the National Fenestration Rating Council (NFRC). These certifications verify that the insulation meets specific requirements for thermal resistance, R-value, and moisture management. For instance, a product with an R-value of R-19 or higher may meet local building codes for energy efficiency.
Certifications for Indoor Air Quality
Natural insulation products can also impact indoor air quality. Look for certifications from organizations like Greenguard Gold or the California Air Resources Board (CARB). These certifications ensure that the insulation meets strict standards for VOC emissions, mold growth, and other indoor air quality concerns. A Greenguard Gold certification, for example, requires the product to meet or exceed stringent VOC emission limits, ensuring a healthier indoor environment.
