Flexible Duct Benefits
Affordability
Flexible ducts are an affordable air movement option that can save money on installation and upkeep. Their affordability can free up budget for other aspects of a build.
Flexibility
The key benefit of flexible air ducts is right in the name: they are flexible. They can easily work around bends, curves and other obstructions. They fit into small, tight spaces where rigid metal ducts won’t work.
Insulation
Flexible ducts are already insulated as part of their three-layer construction, and require no seam sealant, which provides a significant advantage against heat loss and leaks.
Durability
Flexible ducts are made from materials like fiberglass, vinyl, or reinforced fabric, making them lightweight and durable. They come in a wide variety of diameters from 2 inches to 22 inches.
Flexible Air Duct vs. Rigid (Metal) Duct
| Flexible Air Duct | Rigid (Metal) Duct |
|---|---|
| Affordable | Expensive |
| Comes already insulated | Requires secondary insulation |
| Leak-free, single-body construction | Requires connecting seams every few feet; multiple opportunities for air leakage |
| Easily bends around corners and obstructions | Can only bend at 90-degree angle with use of connecting elbow (another chance for leakage) |
| Product has three layers for added durability (inner core, insulation, outer wrap) | Only one layer |
| Fast installation | Difficult installation |
