New and Underutilized Technology: Duct Sealants
The following information outlines key deployment considerations for duct sealants within the Federal sector. This information spans:
Aerosol sealant is injected into the ductwork to seal leaks. This can save energy and costs associated with heating, cooling, and fan operation depending on building type.
Condensing boilers are appropriate for most building applications.
Key Factors for Deployment
Sealing ductwork should be a standard energy conservation measure evaluated during design, construction, major renovation, or other HVAC projects.
Federal energy savings, cost-effectiveness, and probability of success are ranked 0-5 with 0 representing the lowest ranking and 5 representing the highest ranking. The weighted score is ranked 0-100 with 0 representing the lowest ranking and 100 representing the highest ranking.
