Best Answer

You insulate any ductwork where you want to control the temperature diffences between the inside and outside of the duct. One example would be the combustion air duct, usually a round sheet metal line that comes from the outside and ends near the furnace and/or water heater. Typically this would be insulated with fiberglass padding held in place with a plastic coating. Larger, rectangular ductwork can be insulated with internal or external insulation, not always fiberglass, of verying thicknesses.

Does duct tape insulate?

Duct tape does not provide insulation, but it can be used to seal ductwork or repair items temporarily. For insulation, it is better to use materials specifically designed for that purpose such as foam insulation or fiberglass.


What happens if insulation on the inside of duct comes loose?

If insulation on the inside of duct comes loose, it can reduce the efficiency of the HVAC system by allowing conditioned air to escape through the loose insulation. It may also lead to poor indoor air quality as the insulation particles can circulate in the air. Additionally, loose insulation can create a fire hazard if it comes into contact with hot surfaces.


What do you need to do when you have some water dripping through your AC vent?

it is cold-air-induced condensation in the supply ducting. the outside of the duct is wrapped in insulation to prevent this. that insulation has failed, and the condensation is finding its way into your room. accessing the ducting will be difficult, but foam stripping and good-ol duct tape will fix the break in the insulation.

Why is duct tape a good insulator?

Duct tape is a good insulator because it has a low thermal conductivity, meaning it does not readily transfer heat. It is also flexible and has a tight adhesive seal, which can help trap air and create a barrier that blocks heat transfer. However, duct tape may not be as effective as specialized insulation materials designed for thermal insulation.


Can duct tape prevent heat loss through conduction?

Duct tape is not an effective insulator to prevent heat loss through conduction. It would be more beneficial to use proper insulation materials such as fiberglass, foam, or cellulose for this purpose. Duct tape may be used for sealing leaks in ductwork to prevent air loss, but it does not provide significant insulation against heat transfer.
