Why Insulate Ductwork? Insulated ducts have been the standard for decades now. No building inspector worth his or her salt is going to let any builder or HVAC contractor get away with installing ducts that aren't insulated.

This, of course, is a good thing! Duct insulation keeps air that's supposed to be cool cool and air that's supposed to be warm warm. If your ducts aren't insulated, you're probably paying way more than you should to cool and heat your home. And since your HVAC system will need to work harder to power through the thermal loss or gain that's going on in your ducts, you'll have to replace it sooner than if you had insulated ducts. The choice is yours, and you're going to be better off no matter which option you choose.

We actually think one option makes more sense than the other, but let's not get into that just yet. First, let's consider what's involved in each endeavor.

Adding insulation to your ducts isn't as simple as getting some duct wrap and taping it together. Ok, some people and contractors do insulate their ducts this way. And technically, the ducts are insulated afterward. But if you go this route, you're forgetting something super important: duct leaks. Duct leaks are the scourge of energy efficiency and indoor air quality. Gaps, cracks, holes, rusted out corners When air leaks through your ducts, it brings contaminants into your indoor air and reduces the efficiency of your HVAC system.

By not addressing duct leaks, you're literally polluting your clean, filtered, conditioned air with dirty, unfiltered, unconditioned air! Remember, a lot of your ductwork is either in your crawlspace or your attic.

Anyway, the point of all this is to highlight the fact that you've got to seal the leaks before you insulate the ducts. Insulation blocks the movement of heat, but it can't stop air leaks. Dirty air will still enter your ductwork through the leaks, even after you add insulation.

If you decide to insulate your old ducts, just make sure you or your contractor follows this order of operations:. Out with the old, in with the new! Wrapping the duct with AP ArmaFlex still provides excellent protection from energy loss and condensation, as well as some vibration-dampening benefits. Fiberglass lining, when damaged, allows moisture penetration and "wicking" that lead to mold, loss of thermal efficiency and costly replacement.
