Types of Ducts in HVAC Systems
Sheet Metal Ducts
These are the most common—usually made of galvanized steel or aluminum. Durable, fire-resistant, and ideal for commercial and industrial spaces.
Flexible Ducts
Lightweight, easy to install, and cost-effective, especially for tight spaces. Best for residential or low-pressure systems.
Fiberglass Duct Board
Great for noise reduction and thermal insulation. These are pre-insulated but require careful installation to avoid moisture problems.
