The DM44 - 440mm square casing & soot door is part of our premium line of high-quality Isokern DM block system chimneys. This double-wall system is designed to maintain flue gas temperatures while minimizing heat transference to the outer casing. The separation of the inner and outer components allows for thermal movement, significantly reducing the risk of cracking, leaking, or staining.
The DM44 is straightforward and quick to install, available in three outer casing sizes: DM36, DM44, and DM54. This versatile casing is suitable for use with inserts, stoves, open fires, and cookers burning wood, solid fuel, oil, or gas (excluding condensing appliances like Biomass & Pellets).Constructed from pumice, a natural insulator, the DM system allows flue gases to rapidly reach optimal temperatures, enabling your heating appliance to perform at its best shortly after ignition. The chimney remains warmer for longer as the heat output decreases, enhancing performance and reducing the likelihood of condensation and soot buildup.
Additionally, the Isokern DM system is HETAS approved and CE marked, with a designation number: Double Module DM System Chimney* T450 N1 D 3 G(00). For smooth installation, please refer to the included instructions in our guides.
