What is the difference between PTCS and Prescriptive Duct Sealing?                      

​While the specifications for both types of duct sealing have recently been updated to be more aligned, there are two primary differences between the two types.

1) Leakage testing: PTCS Duct Sealing requires a pre-leakage test be conducted prior to sealing and a post-leakage test conducted after sealing. Prescriptive Duct Sealing does not require any pre- or post-leakage testing.
2) Certification training: PTCS Duct Sealing Certification requires training with a PTCS-certified trainer or an approved alternative. Certification is obtained by reviewing an online training. More information about how to become certified can be found on the Training Page.

​The Regional Technical Forum (RTF) provides guidance on installation specifications and BPA determines when to adopt their specifications. Individual utilities may have additional requirements. Please check the customer's utility for additional requirements.
