Round Fixed Finishing Plate 45° - Ø 80 is an essential accessory designed for use with solid fuel and gas/oil appliances, including woodstoves, gas coal effect fires, and various boilers. This top-grade finishing plate ensures a neat and safe exit for your flue system through non-combustible walls.
Constructed from robust 304-grade stainless steel for the outer skin with a thickness of 0.4mm and durable 316-grade stainless steel for the inner skin, also 0.4mm thick, this plate guarantees long-lasting performance. The insulation is made up of compressed rockwool, with densities of 200kg/m3 TWPro and 128Kg/m3, ensuring excellent heat resistance. It is fully welded for added strength and durability.
The TWPro system retains a safe distance to combustibles of 50mm, while the KC system requires 60mm.
