Why this ducting earns its place
Every extraction duct that exits through a wall or roof needs protection. Without a rain cover, water runs in, leaves clog the opening, frost forms, and suddenly your extraction hood is struggling or not working at all. It's a small component with a big job: keep weather out and airflow uninterrupted.
The Combisteel rain cover at 200 mm diameter is the standard size for smaller commercial kitchens, cafés, delis, and compact takeaways. At this size, it sheds water effectively—rain flows around the sides and away from the opening—while maintaining full extraction airflow. The cover is designed to handle everything British weather throws at it: repeated freeze-thaw cycles, driving rain, wind-driven debris, and the occasional snow load.
Fitting is simple. Slip the cover over your external duct outlet, secure it with standard wall or roof fixings, and you're done. Most installations take just a few minutes. Once in place, it disappears into the background and simply works—keeping weather out, letting warm air out, and protecting your extraction system year after year.
