Why Fitting a Crowned Gas Cowl Is a Wise Decision
What Is the Purpose of a Crowned Gas Cowl?
A crowned gas cowl is a steel chimney cap fitted to the upper part of a chimney flue. Its main roles include:
- Shielding from Rain and Blockages: The crown design deflects water and airborne debris, preventing clogs in the flue without affecting airflow.
- Assisting Exhaust Flow: It ensures the steady removal of combustion gases, and prevents downdraughts that could push fumes back into the building.
- Wildlife Deterrent: Acts as a guard to birds, squirrels, and other animals that may attempt to nest in the flue.
The Value of a Durable Crowned Gas Cowl

- Long Service Life: Galvanised metal withstand corrosion, making the cowl last for years.

- Correct Fit: An experienced supplier will help you choose based on the inner dimensions of your flue to ensure an effective fit.
- Regulatory Compliance: Look for suppliers familiar with UK regulations, appliance compatibility, and flue specifications.
- Transparent Service: Confirm return terms to avoid complications during or after the purchase.
