The Benefits of Installing a Crowned Gas Cowl
What a Crowned Gas Cowl Is Designed to Do
A crowned gas cowl is a metal fitting that covers a chimney. It offers three key benefits:
- Rain and Debris Control: It prevents entry of water, leaves, and loose materials from entering the flue, helping to avoid internal damage and obstruction.
- Improved Venting: Assists in the safe and steady removal of gases from combustion appliances, lowering the likelihood of downdraught.
- Animal Prevention: Stops animals nesting that might otherwise clog the chimney.
Why a Good Quality Gas Cowl Matters
A well-constructed gas cowl offers notable benefits over time:
- Resilience: Made from stainless or galvanised steel, it is resistant to corrosion.
- Safety Assurance: Supports safe extraction of indoor air.
- Lower Maintenance: With steady flue function, it limits the need for frequent servicing.
What to Evaluate in a Supplier
When ordering a crowned gas cowl, pay attention to the following:
- Product Materials: Galvanised options are cost-effective. Choose according to your budget and climate.
- Correct Sizing: A reliable supplier will help match the proper size for your chimney flue to ensure airflow.
- Knowledge of Standards: The supplier should follow British safety codes and offer guidance on compliance.
- Clarity on Terms: Check delivery, returns and warranties before finalising your purchase.
Is a Crowned Cowl Better Than a Standard One?
A typical gas cowl helps with airflow regulation. A crowned model, however, includes an overhead barrier which channels water and wind away from the flue — a smart choice for wind-prone areas.
