Additional Information

Additional Information

We supply complete Innerduct solutions including different types (or ratings) of Indoor flexible, corrugated, Innerduct including plenum-rated, riser-rated, and HDPE. Innerduct typically has a small-diameter, the need for specific characteristics or a combination of characteristics, such as pulling strength, flexibility, fire rating, and/or the lowest coefficient of friction, dictates the type of Innerduct required.

Innerduct Example Installation

Plenum Innerduct

Designed for horizontal runs or where vertical runs are inside an air-handling space. A plenum space is a part of a building that can facilitate air circulation for heating and air conditioning systems. Space between a structural ceiling and a dropped ceiling or space under a raised floor are typically considered plenum.

Riser Innerduct

Perfect for runs in non-air handling spaces such as walls directly leading to work-area outlets. Riser-rating is different from Plenum, Riser is a vertical area that passes from one floor to another floor inside a building. For example, an elevator shaft or conduit from one floor to another floor is considered Riser.

HDPE Innerduct

Manufactured from high-density polyethylene (HDPE), intended to be placed inside of Conduit. This Innerduct is lightweight offering maximum flexibility and allowing for installations in small or restricted areas.
