NTA is a leader in building product code evaluation and certification. We offer the most thorough third-party testing and inspection services for a wide range of building products. Our certification programs are nationally recognized and establish a product’s code compliance and provide verification of in-plant quality control measures for products such as moisture barriers, structural plastics, doors and windows, insulation, structural insulated panels, structural assemblies, and numerous other building products. We can even design a certification process to ensure code compliance of new or innovative products. You can trust NTA to complete your project in a timely manner, and guide you every step of the way.
Certification Mark: A symbol of Code Compliance
The NTA Certification Mark is recognized internationally as well as nationally, and provides evidence of code compliance when a product is required to be “listed and labeled”. The Certification Mark also signifies that your product is participating in a certification program that includes a listing report and ongoing follow-up testing and inspection services (surveillance audits and testing).
Scope of Accreditation
We are accredited under ISO/IEC 17065 (view our Certificate of Accreditation) to test a variety of building products. With our highly trained and experienced test lab and our network of auditors nationwide, we can partner with you wherever you are!
