About this asset

This vertical vapour barrier roof outlet Revit family features a flexible membrane flange securely bonded to a metallic cylindrical drainage spigot. Comprising a broad square bituminous or synthetic membrane flange connected to a smooth cylindrical drainage spigot, this roof penetration unit is engineered for flat roof assemblies. The dark textured membrane apron provides an integrated flashing zone designed for hot-air welding or torching directly into primary vapour barrier layers. Below the collar, a seamless brushed metallic drop pipe extends downward to connect into rainwater piping runs. The circular drainage throat sits flush with the membrane plate, ensuring water and condensation trapped above the deck flow unobstructed into internal downpipes without leakage.

The download is a 481 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Insert this Revit family into MEP drainage models or architectural roof section details. MEP engineers can align the vertical connector to gravity downpipe networks, routing rainwater conductors through structural floor slabs. In coordinated BIM views, the family provides clear spatial clearance below the roof deck, verifying collision-free installation alongside HVAC ducting, cable trays, and structural joists in ceiling cavities.

Specifiers incorporate this drainage penetration in commercial, industrial, and multi-residential flat roof designs requiring airtight vapour control. It suits warm-roof build-ups, unvented roof decks, and podium terraces where maintaining vapour barrier integrity around penetrations is critical. Typical pairings include internal cast iron or PVC rainwater pipework, rigid insulation boards, and multi-layer roofing membranes across technical drainage schematics, clash detection runs, and full building envelope documentation sets.
