The Role of a Crowned Gas Cowl
A gas flue crown cover 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, 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: Made from stainless or galvanised steel, it is designed to endure weather.
