The DM44 - 180mm ID x 100mm high offset block is an integral part of the Isokern DM block system, designed for premium chimney performance. This double-module system not only maintains optimal flue gas temperatures but effectively prevents heat transference to the outer casing, enhancing safety and efficiency. The innovative separation of inner and outer components allows for thermal movement, significantly reducing the risk of cracking, leaks, or staining over time.
Available in three outer casing sizes (DM36, DM44, and DM54), this versatile system is ideal for use with various heating appliances, including inserts, stoves, open fires, and cookers that burn wood, solid fuel, oil, or gas (excluding condensing appliances). Pumice, renowned for its natural insulating properties, ensures the chimney swiftly reaches optimal temperature, thereby enhancing appliance performance while mitigating condensation and soot build-up. HETAS approved and CE marked, the Isokern DM system guarantees both efficiency and safety.
