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 sits atop a chimney. It serves three important purposes:
- Rain and Debris Control: It blocks water, leaves, and loose materials from entering the flue, helping to prevent internal damage and obstruction.
- Improved Venting: Assists in the reliable removal of gases from combustion appliances, reducing chances of downdraught.
- Animal Prevention: Stops animals nesting that might otherwise obstruct the chimney.
Reasons to Use a Reliable Gas Cowl
A long-lasting gas cowl offers notable gains over time:
- Resilience: Using stainless or galvanised steel, it is resistant to corrosion.
- Safety Assurance: Supports safe extraction of indoor air.
- Lower Maintenance: With steady flue function, it reduces the need for frequent servicing.
What to Evaluate in a Supplier
When sourcing a crowned gas cowl, pay attention to the following:
- Product Materials: Steel is durable and weather-resistant. Choose according to your budget and climate.
- Correct Sizing: A reliable supplier will assist in selecting 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: Look for transparent pricing before finalising your purchase.
Comparing Types of Gas Cowls
A standard gas cowl is built for airflow regulation. A crowned model, however, includes an overhead barrier which channels water and wind away from the flue — a smart choice for frequently damp areas.
