The DM36 - 150mm ID x 500mm high access flue block is an exceptional component of the Isokern DM block system. This high-quality system chimney features a double wall construction that cleverly maintains flue gas temperatures while preventing heat transfer to the outer casing. Thanks to its innovative design, which separates the inner and outer components, the DM36 allows for thermal movement, significantly reducing the risks of cracking, leaks, and stains.Constructed from pumice, a natural insulator, the DM36 has unique properties that enable quick attainment of optimum flue gas temperatures, enhancing the performance of heating appliances like inserts, stoves, open fires, and cookers using wood, solid fuel, oil, or gas (excluding condensing appliances such as Biomass and Pellets).
Pumice's insulating abilities also keep the chimney warmer for longer, aiding consistent performance and reducing condensation and soot build-up.The Isokern DM system is HETAS approved and CE marked, boasting a designation number: T450 N1 D 3 G(00). The DM system is available in three outer casing sizes—DM36, DM44, and DM54—providing flexible solutions for various installations.
