- • Weather Protection: Guards the flue termination against water ingress, birds and debris.
- • Best for: Homeowners fitting stoves, log burners and pizza oven flues using factory made insulated wall flue systems.
- • Not ideal for: Very large diameter masonry chimneys or bespoke flue systems that need custom cowls.
Designed to terminate factory made insulated wall flue systems while preventing smoke backing into the house. Constructed from stainless steel sheets 0.5mm to 0.8mm thick and resistant to acidic condensate formed during combustion.
Dry, clear flue termination - with a fitted chimney cap
Stainless steel sheets of 0.5mm to 0.8mm thickness create a rigid cap that sheds rain and blocks vermin and debris at the flue outlet. The capped termination sits over the flue to close the top while leaving the exhaust path open.
Keeps the flue throat dry and free from blockages, reducing corrosion risk and improving appliance performance.
Reduced smoke re-entry and draughts - thanks to cowl design
Installing a cowl on the chimney stop allows exhaust gases to discharge while preventing downdraughts that can push smoke back down the flue. The termination design suits factory made insulated wall flue systems for straightforward installation.
Prevents smoke entering living spaces and helps maintain a steadier burn from stoves and ovens.
Longer service life in acidic conditions - with corrosion-resistant material
Materials are described as resistant to the corrosive effects of acidic condensate formed during combustion, helping the cap withstand wet, acidic exhaust over time. Durable construction resists accelerated wear where condensate forms regularly.
Offers greater longevity in installations prone to acidic flue gases, reducing the need for frequent replacements.
