Benefits of Spiral Duct

Why Choose Spiral?

As the market continues to grow for Spiral Duct, you may be asking yourself…Why choose spiral duct over traditional rectangular ductwork? There are infinite reasons to choose spiral duct.  Here are a few spiral duct advantages:

Visually Appealing
  • Spiral duct provides a clean, contemporary aesthetic that can enhance a building’s architectural features
  • Paintlock spiral can be painted to blend in with the ceiling, or painted a bold color to stand out as an architectural feature of the room

  • The strong seams give spiral duct increased strength and rigidity.  It requires less support, less hangers, less joints and less connections, adding a clean and attractive look

  • Round duct made with gasketed joints allows the system to stay clean of dirt streaking, and require no messy sealant, also contributing to the clean look for the system.
