Choosing a Crowned Gas Cowl for Your Chimney
What a Crowned Gas Cowl Is Designed to Do
A crowned gas cowl is a metallic guard that sits atop a chimney. It performs three essential roles:
- Rain and Debris Control: It blocks water, leaves, and loose materials from entering the flue, helping to avoid internal damage and obstruction.
- Improved Venting: Assists in the reliable removal of gases from combustion appliances, lowering the likelihood of downdraught.
- Animal Prevention: Acts as a barrier against squirrels and birds that might otherwise obstruct the chimney.
Advantages of a High-Grade Cowl
A dependable gas cowl offers notable gains over time:
- Resilience: Using stainless or galvanised steel, it is designed to endure weather.
- Safety Assurance: Prevents hazardous fumes from entering indoor air.
- Lower Maintenance: Through correct ventilation, it lowers the need for frequent servicing.
What to Evaluate in a Supplier
When ordering a crowned gas cowl, consider the following:
- Product Materials: Stainless steel lasts longer. Choose according to your budget and climate.
- Correct Sizing: A reliable supplier will guide you to choose the proper size for your chimney flue to maintain 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.
Crowned vs. Standard Gas Cowls
A standard gas cowl mainly supports airflow regulation. A crowned model, however, includes an overhead barrier which channels water and wind away from the flue — a smart choice for exposed areas.
