Heating ducts, also known as HVAC ducting or AC ducting, are conduits that deliver either warm or cool air to cool, heat or ventilate rooms. They are connected to an HVAC unit which filters and either heats or cools the air before sending it through the ducts.
Most heating and cooling ducts can be insulated using fiberglass insulation, which comes in flexible and rigid forms depending on your needs. While the flexible type is relatively easy to install, provided you have the duct mastic (adhesive) required, rigid insulation is much more challenging to install on one's own. For flexible insulation, you'll want to apply the duct mastic to the duct joints where the elbow connects to the duct. Then you'll cut the insulation to the proper size, wrap the insulation around the duct and pinch the seam closed. Finally, secure the insulation with strips of foil tape.
In short, yes. Flexible ducting can be used for heating and cooling and comes with some pros and cons. The most significant advantages of using flexible ducting are that it is cheap, often easier to install and requires fewer joints thanks to its versatility. On the other hand, flexible ducting is considered temporary, with a lifespan of about 15 years. These are the main factors to consider when choosing between flexible or rigid ducts.
