Installs Faster, With Smaller Crews
InspiralR and Floval are designed to move quickly on site. Pre-insulated and delivered in long sections, they come ready to hang with no field wrapping or separate insulation required. With lightweight panels and simple connection methods, crews can install duct in tight ceilings and crawlspaces without fighting rigid metal sections or custom transitions.
Because most sections are designed and cut before delivery, teams can skip the layout guesswork and move straight to setting duct. Whether you’re working overhead or across finished spaces, fewer moving parts means fewer delays.
Easier on Crews, Especially Overhead
Anyone who's hauled 24" duct overhead knows what it does to your back. Floval and InspiralR systems are built from phenolic insulation—making them a fraction of the weight (over 70% lighter) of traditional metal duct with external wrap. That means easier lifts, safer handling, and less strain on your crew day to day.
The lightweight design also eliminates the need for oversized supports or trapeze hangers. Systems can hang cleanly with minimal supports, making them ideal for ceiling installs or long corridor runs where overhead clearance is tight.
No Special Tools, No Extra Trades
InspiralR and Floval can be installed using common hand tools—no sheet metal brakes, no pin spotters, and no field-fabricated insulation. Everything needed for assembly is included: flanges, sealants, gaskets, or adhesives depending on the system.
With competitive price and timely delivery, Shengquan sincerely hope to be your supplier and partner.
For project managers and foremen, this means less dependency on specialized labor. Crews familiar with duct installation can assemble phenolic systems with minimal training (we have a brief online training video) or adding insulators to the job. It’s ductwork—just streamlined.
Sealed from the Start
InspiralR and Floval are designed to meet or exceed SMACNA phenolic duct construction standards, including low-leakage performance for both pressure and return systems. With tight seals at the flanged joints and no exposed liner to fail, airflow stays where it belongs.
That means fewer adjustments during balancing, more predictable system performance, and peace of mind knowing you won’t need to revisit joints that fail under pressure testing.
Ideal for Finished Interiors and Space-Constrained Projects
Floval’s flat oval design is ideal for corridors, drop ceilings, or tight plenum spaces where rectangular duct doesn’t fit and spiral might hang too low. InspiralR is well suited for straight runs and vertical drops that benefit from a round form with cleaner airflow.
Both systems are built for low-profile installs—pre-insulated, clean-looking, and field paintable for retrofits, schools, hospitals, and interior renovations. No wrap, no mess, and less disruption to building occupants.
