Screwfit Anti Downdraught Chimney Liner Cowl
The screwfit anti downdraught chimney liner cowl is engineered to help stabilise flue performance on flexible stainless-steel liners used with wood-burning, coal and multifuel appliances. By dispersing wind turbulence around the terminal, it minimises smoke blow-back, helps maintain a steady draw and prevents rain, debris and birds from entering the flue. Its unique screwfit system ensures a strong mechanical connection without additional clamps or sealants, making installation quick and secure.
If your stove or fire experiences inconsistent draught, periodic downdraught or small amounts of smoke entering the room during windy conditions, the screwfit anti downdraught chimney liner cowl offers a simple, reliable and long-lasting solution. Its aerodynamic hood design channels airflow upward, promoting positive flue pressure while ensuring continuous extraction of combustion gases.
