When it comes to sealing around vents and registers in a duct system, the right adhesive tape is essential. Aluminum tape is the ideal choice for this job, as it is thin and easy to work with. However, be careful when applying it, as it can break if stretched too much. For more information on sealing ducts, you can consult the guides Sealed and Insulated Flexible Ducts, Metal Ducts, and Fiberboard Ducts.
The Department of Energy also provides standard work specifications that can help guide you on how to properly seal duct covers.If someone has already attempted to pre-seal the drywall edges of a ceiling vent, you can use an infrared camera in conjunction with fan door checks to detect air and heat leaks at duct openings and smoke ducts. This is especially useful if there is a significant temperature difference between the unconditioned space and the conditioned space in the house. Air sealing should be done using putty, foam, or any other suitable material. If you are sealing from the attic or mezzanine side, make sure to remove the insulation as needed to access the areas that need to be sealed. Hermetically sealing roof or floor duct covers of an existing home is essential for reducing air leaks and preventing unconditioned and unfiltered air from entering the conditioned space.
Professionally sealed comfort supply systems are significantly airtight at all joints and connections, ensuring that air conditioning gets where it needs to be at the right temperature without absorbing contaminants from mezzanines and attics. To ensure that your home's air conditioning system works properly, it is important to properly seal around vents and registers in a duct system. Aluminum tape is the best way to do this job, as it is thin and easy to work with. Make sure to follow the Department of Energy's standard work specifications for guidance on how to effectively seal duct covers. Additionally, use an infrared camera in conjunction with fan door checks if there is a significant temperature difference between the unconditioned space and the conditioned space in the house.
Finally, hermetically seal roof or floor duct covers of an existing home for maximum efficiency.
