Overview
The intent of this brief is to provide code-related information about properly sealing heating, ventilating, and air conditioning (HVAC) register boots to help ensure that what is proposed regarding sealing the register boot will be accepted as being in compliance with the code. Providing consistent information to document compliance with codes and standards to all relevant parties responsible for verifying with those codes and standards (e.g., code officials, builders, contractors, designers, etc.) is expected to result in increased compliance and more timely, less challenging and more uniform plan review and field inspections.
