Select your State

In general, TERs that have been vetted through the ANSI 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 click on the appropriate state. For states that we cannot seal automatically (California, Illinois, Nevada, 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.

Select a state or province/territory to generate a sealed version of Thermo-Sheath (Blue) Structural Sheathing Installation Instructions. In the map below, dark green indicates that a sealed version of the document is available for download and light green indicates that a seal for the selected state or province/territory can be requested.
