Starting today, any residential building code official can obtain access to our Duct and Envelope Tightness Verifier training for FREE.
This training covers the building science basics of envelope and duct leakage testing, contains straight-forward how-to videos illustrating the proper use of testing tools (both Retrotec and Energy Conservatory brands), and includes a simple report template that can be used to document the testing results.

Good afternoon,
If this free course still available, I would like to sign up. Thank you
Here’s a link to the DET course, Rodney. If you’re a building code official, get in touch with me to discuss free access to the training.
