Description
Designed to cap an insulated flue, the 250mm slimline storm cowl sits on the final length of 250mm double skin pipe above your roof. It stops rain running straight down the flue and helps stop wind gusts pushing smoke back into the room. The slimline shape keeps the roof line tidy, which matters on modern homes where the flue is on show.
250mm Slimline Storm Cowl Features
- Stainless steel cowl: resists rust from salt air and winter rain, so it lasts on exposed Cape Town roofs.
- Double skin flue fit: made to match 250mm insulated flue, so the outer skin and inner liner both finish cleanly.
- Slim storm end piece: lets smoke out freely while shielding the opening from side wind.
- Light to mount: it weighs 1.45 kg, so it puts little load on the top section.
Which flues does it fit?
It fits 250mm double skin, or insulated flue, systems, often used on large wood fireplaces, built-in units and braai flues that run through ceilings. For single wall pipe you need a single skin cowl instead. See all sizes in our slimline storm cowls for insulated flues, or browse the wider flues and accessories range.
Fitting note
The cowl only works well if the flue ends high enough above the roof and nearby walls. Our team sets the height, fits the flashing and secures the top section during our chimney cowl installation in Cape Town.
Can I fit a slimline cowl to an existing insulated flue?
Usually, as long as the flue is 250mm double skin and in good condition. We check the pipe, joints and flashing first, then swap the old end for the new one.
