Fabric ducting options

From round to rectangular, fabric ducting systems can be constructed from a wide range of shapes to fit the heating and cooling needs and interior design of any space.

Round ducts might take up too much space in an office with low ceilings, for example, while a wide and shallow ellipse duct might be an ideal fit.

The requirements of each specific application, along with visual design considerations, will determine the shape best suited for each particular space.

All of our Premium, Classic, and Recycled fabrics carry a non-prorated 10-year warranty with an extended warranty up to 20 years (prorated after 10) for systems that use hold-open (rings or helix) and tensioning. Actual use in the field consistently demonstrates a service life of 15 years or longer. Prihoda Light, which is intended for economy or temporary applications, carries a warranty of two years or 50 washing cycles.

Round

Round is by far the most common shape. Round diffusers are easy to tuck out of the way, and at the same time they function well when made to stand out in the space as a design element. Wherever round diffusers are installed, air distribution is custom-engineered to ensure comfortable, draft-free spaces.

Half-round

Half-round are excellent choices for lower ceiling installations. Half-round diffusers can be suspension mounted or surface mounted to the ceiling.

Quarter-round

Quarter-round ducts require a wall-to-ceiling junction and are most often specified in offices and areas struggling for space. Quarter-round ducts provide comfortable ventilation unobtrusively. The addition of the soft fabric in ceiling corners also reduces sound reverberation off walls and ceiling.

Ellipse

An ellipse duct is often specified when ceiling height is a concern. The air volume and the available height will determine the width of the ellipse. Usually, the inlet spigot will be in the top of the duct so that it’s not visible once installed. As with the half-round, ellipse ducts may be suspension mounted or surface mounted to the ceiling.

Rectangular

Rectangular ducting can be used for either negative pressure (return) applications or for the more common positive pressure supply. An aluminum track at each corner provides support and tensioning along the length of the duct, and evenly spaced threaded rods provide width tensioning along the duct.
