R2+® SILVER, R2+® MATTE, and R2+® BASE Fire Performance in Exterior Walls of Building of Type I-IV Construction

Note: In general, TERs that have been vetted through the ANAB ISO/IEC 17065 accreditation process do not require an engineer’s seal to be approved for use by any building official. If, however, you need an engineer’s seal please select the appropriate state. For states that we cannot seal automatically (California, Hawaii, Puerto Rico, and Canada), you can click on the state to send us a request for a sealed document. DrJ’s desire is to fully support the appropriate deployment of innovation and new technologies through all professional engineering means needed.
