The 2pc. Round Fixed Finishing Plate (150) 45° - Ø 175 is designed for a professional, clean finish where your flue passes through a non-combustible wall. This product is perfect for use with solid fuel and gas/oil appliances, including woodstoves, gas coal effect fires, and boilers.
Made from robust 304-grade stainless steel on the outer skin and 316-grade stainless steel on the inner skin, both 0.4mm thick, this finishing plate ensures durability and performance. The insulation consists of compressed rockwool with densities of 200kg/m3 TWPro and 128Kg/m3. Fully welded for extra strength, it maintains a safe distance of 50mm to combustibles (60mm on KC parts).
HETAS approved and CE marked, the TWPro Twin Wall Insulated Chimney parts are easy to install, secured together with a locking band. Ensure you maintain the recommended clearance from the flue to any combustible materials such as wood or plasterboard.
