The DM44 - 45° flue pipe entry kit, part of the Isokern DM system, is a high-quality solution for all your chimney needs. This robust double wall system is crafted from pumice, a natural insulator ensuring optimal flue gas temperatures and reducing heat transference to the outer casing. This separation allows for thermal movement, minimizing the risk of cracks and leaks.
Perfect for stoves, fireplaces, and cookers using wood, solid fuel, oil, or gas (excluding condensing appliances like biomass and pellets), the DM44’s installation is quick and straightforward.
