Johns Manville PVC Penetration Pan, Gray Rigid PVC Membrane Flashing Accessory
The Johns Manville PVC Penetration Pan is a one-piece, vacuum-formed pan with a square base flange used to seal uneven or difficult-to-flash penetrations through a PVC roof membrane. It is molded from 125 mil (3.18 mm) impact-resistant rigid PVC, slit on one side for positioning around pipes and other objects. A welding tab is included so the pan can be heat-welded into the membrane after installation.
Key Features:
- One-piece molded: Vacuum-formed and fabricated as a single impact-resistant rigid PVC unit for reliable sealing.
- Thick 125 mil PVC: Made from 125 mil (3.18 mm) thick rigid polyvinyl chloride for durability at penetration points.
- Square base flange: Square base flange provides a welding surface that integrates with the roof membrane.
- Slit for retrofit: Slit on one side so the pan can be positioned around existing pipes and penetrations.
- Welding tab included: A welding tab is included to seal the penetration pan once it is installed.
- Gray finish: Supplied in gray to coordinate with typical PVC membrane installations.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Penetration pans save time on pipes and conduit runs that are awkward to individual-flash; weld the flange perimeter fully and seal the slit seam with the included tab. Keep the 125 mil PVC compatible with the membrane being installed, and follow the membrane manufacturer's hot-air welding practice for seam integrity.
Hot-air welding PVC membrane involves high temperatures and fumes; follow the roofing system's safety procedures and wear appropriate protective equipment.
Order the Johns Manville PVC Penetration Pan for a clean, weldable seal around difficult membrane penetrations.
