Why is Ductwork Insulation important?
Ductwork insulation ensures that air traveling through the duct system will stay at the desired temperature and won't "leak" out.
Leaking air results in unnecessary energy loss, which means that your HVAC system will have to work even harder.
This will cause higher utility bills as a result of wasted energy … not good for you or the environment.
Without proper ductwork insulation, you could be losing 10-30% of the energy used to heat or cool your home.
A good level of ductwork insulation will prevent not only energy wastage, but also leaks, temperature drops, and condensation buildup.
Different Types of Insulation
The predominant insulation material for ducts is fiberglass. It can be applied in either a flexible or rigid form and comes in a variety of densities and thicknesses.
The flexible blanket insulation is available in rolls for convenience in shipping and ease of application to round or rectangular ducting. Flexible insulation easily conforms to irregular surfaces.
Rigid insulation comes in pre-formed boards which are bonded with a thermosetting resin. All duct insulation should have a foil or vinyl facing on the exterior side which serves as a vapor retarder.
This prevents moisture from being absorbed into the fiberglass and thus maintains insulation ability.
