The DM44 - 200mm ID x 150mm offset block is an integral part of the high-quality Isokern Double Module (DM) chimney system. This advanced system is engineered for optimal thermal efficiency and safety, making it an excellent choice for various heating appliances, including stoves, open fires, and cookers that burn wood, solid fuel, oil, or gas (excluding condensing appliances like Biomass and Pellets). Constructed from pumice, a natural insulator, this block maintains flue gas temperatures and prevents heat transference to the outer casing.
The double-wall design allows for thermal movement, significantly reducing the risk of cracking, leaking, and staining. The DM44 system is available in three sizes: DM36, DM44, and DM54, ensuring the perfect fit for your chimney requirements. HETAS Approved and CE marked, the Isokern DM system guarantees top-notch quality and performance.
For ease of installation, detailed guides are provided.
