About this asset

This T-shaped chimney pot Revit family models a classic anti-downdraught flue terminal with a hollow cross-barrel atop a tapered cylindrical stem. Modelled as a single solid form, this terminal element features an elongated horizontal barrel mounted directly onto a vertical tapered shaft. Both circular ends of the top pipe remain open to facilitate crossflow ventilation and prevent downdraughts into the flue below. Symmetrically flanking the midsection are two conical buttress lugs that widen downward along the body, mimicking cast construction techniques typical of historic terracotta or fabricated metal cowls. The geometry displays clean, smooth curved transitions with uniform wall thicknesses across all openings, presented in a clean monochromatic grey surface.

The download is a 358 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.

Load this.rfa component directly into a Revit project to cap chimney stacks or exhaust masonry penetrations. As a standalone specialty equipment family, it positions easily over roof level geometry, parapets, or flue liners in plan and 3D views. Assign project-specific materials via Revit's material browser to represent weathered clay, unglazed terracotta, or painted metal finishes across your detailed roof elevations and sections.

Intended primarily for residential architecture, period renovations, and rustic cottages, this anti-downdraught cowl completes accurate exterior chimney assemblies. It suits conservation projects, country houses, and domestic roofscape visualisations where conventional open pots require functional downdraught protection. Designers working on building envelope documentation and technical roofing packages can integrate this element seamlessly alongside ridge tiles, flashing details, and masonry chimney breast schedules to maintain historical verisimilitude.
