Top Reasons to Install a Crowned Gas Cowl
How Does a Crowned Gas Cowl Help?
A crowned gas cowl is a steel chimney cap fitted to the summit of a chimney flue. Its main roles include:
- Shielding from Rain and Blockages: The crown design diverts water and airborne debris, avoiding blockages in the flue without affecting airflow.
- Assisting Exhaust Flow: It improves the efficient exit of combustion gases, and prevents downdraughts that could push fumes back into the building.
- Wildlife Deterrent: Acts as a block to birds, squirrels, and other animals that may attempt to nest in the flue.

- Long Service Life: Stainless steel resist rust, making the cowl last for years.

- Regulatory Compliance: Look for suppliers knowledgeable about UK regulations, appliance compatibility, and flue specifications.
- Transparent Service: Confirm return terms to avoid complications during or after the purchase.
