Who certifies NAIMA Metal Building 202-96 insulations?
The National Association of Home Builders (NAHB) Research Center makes quarterly unannounced inspections of NAIMA member plants where they witness quality control procedures and records. Then they test randomly selected specimens of products from stock. Tests are conducted in accordance with ASTM (American Society for Testing and Materials) methods on the factors that affect thermal performance, such as thickness and thermal resistance. During an in-plant inspection, the weight, length, width, thickness, and thermal conductivity of each product are measured. The results must meet the requirements of the NAIMA 202-96 Standard in order to be certified. Additional tests are performed by Underwriters Laboratories and other laboratories according to ASTM methods for fire hazard classification, odor emission, corrosiveness and moisture sorption. All test requirements are detailed in the NAIMA 202-96 Standard.
