PlasCity manufactures a complete range of PVC PI insulation ducting channels used to join, seal, and finish insulated ductwork in HVAC systems. Each profile is precision extruded for a secure fit and long term durability.
What is PI insulation ducting
PI stands for pre-insulated. These channels are the joining and finishing accessories used on pre-insulated duct panels, not the panels themselves.
They hold panel edges together, seal joints, and give exposed corners a clean finish.
This range includes:
- PVC Invisible Flange Joint, for a concealed, clean finish between duct sections
- PVC H Bayonet, for securing insulation panel edges
- PVC Flange U, F, and G Sections, for different flange joining configurations
- PVC Flange T Bar, for T shaped duct intersections
- PVC End Corner Edges, for finishing exposed duct corners
What to check before selecting a supplier
- Profile fits your panel thickness without gaps
- Consistent wall thickness across the full length
- No warping, cracking, or brittleness on bend test
- UV and temperature stability for the site conditions
- Ability to match existing duct system specs from a drawing or sample
- Supplier can produce matching profiles for the full range, not just one piece
