Why Fitting a Crowned Gas Cowl Is a Wise Decision
How Does a Crowned Gas Cowl Help?
A crowned gas cowl is a metallic device fitted to the upper part of a chimney flue. Its main roles include:
- Shielding from Rain and Blockages: The crown design diverts water and airborne debris, preventing clogs in the flue without affecting airflow.
- Assisting Exhaust Flow: It ensures the steady removal of combustion gases, and helps stop downdraughts that could push fumes back into the building.
- Wildlife Deterrent: Acts as a barrier to birds, squirrels, and other animals that may attempt to nest in the flue.
The Value of a Durable Crowned Gas Cowl
Spending on a dependable cowl brings multiple long-term benefits:
- Long Service Life: Galvanised metal resist rust, making the cowl last for years.
- Improved Safety: Keeps combustion gases out of your living space.
- Maintenance Reduction: By preserving flue function, you’ll face fewer chimney cleanings and repairs.
How to Assess a Chimney Cowl Supplier
When sourcing a cowl, take into account the following aspects:
- Material Quality: Both materials offer different levels of durability—choose based on exposure and lifespan expectations.
- 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 who follow UK regulations, appliance compatibility, and flue specifications.
- Transparent Service: Confirm delivery policies to avoid complications during or after the purchase.
Should You Choose a Crowned or Standard Gas Cowl?
