Screwfit Solid Fuel Chimney Liner Cowl The screwfit solid fuel chimney liner cowl is a robust, secure and highly effective solution for connecting a chimney terminal to a flexible stainless-steel flue liner on solid fuel systems. Designed specifically for wood, coal and multifuel appliances, the screwfit mechanism offers a strong mechanical connection that eliminates the need for additional clamps or strap systems. This ensures fast installation, long-term stability and dependable flue performance in all weather conditions. For installers seeking a secure liner-to-terminal connection that withstands thermal expansion, vibration and exposure, the screwfit solid fuel chimney liner cowl provides a professional-grade upgrade. Its aerodynamic hood reduces wind turbulence at the flue exit, helping to improve draw and minimise smoke blow-back. Integrated mesh protection also prevents birds and debris entering the chimney, ensuring safe and consistent operation year-round.
