C-Cap Ventilated Capping Cowl

Injection-moulded from durable, recyclable ABS thermoplastic, the C-Cap fits snugly over the chimney pot, secured by galvanized steel spring wires. It can be easily fitted to any standard round chimney pot of the appropriate size and is lightweight enough to be carried up the roof in multiples, with installation taking just seconds.

Thousands of C-Caps are installed across the UK, including as far north as the Orkneys. It is the only cowl for disused chimneys that guarantees 100% protection against rain, snow, debris, and nesting birds. Ensure pots are in good condition; any cracked pot should be replaced or securely strapped to allow for the insertion of the C-Cap retaining wires.

As recommended by The Energy Saving Trust, capping disused chimneys is crucial for minimizing heat loss from the home. The C-Cap’s unique design also allows for continuous, trickle ventilation of the flue.
