The DM44 - 200mm ID starter flue block is a top-tier component of the Isokern DM block system, known for its superior construction and outstanding insulation properties. This double-module system features a dual-wall design that efficiently maintains flue gas temperatures while minimising heat transference to the outer casing. The separation between the inner and outer components allows for thermal movement, reducing the risk of cracking, leaks, or stains.

Quick and straightforward to install, the DM44 is available in three outer casing sizes: DM36, DM44, and DM54. Suitable for use with various appliances, including wood-burning inserts, stoves, open fires, and cookers operating on solid fuel, oil, or gas (excluding condensing appliances like Biomass and Pellets). Pumice, a natural insulator, sets this system apart by quickly bringing flue gases to optimal temperatures, enhancing appliance performance, and reducing condensation and soot build-up.

The Isokern DM system is HETAS-approved and CE-marked, ensuring top-notch quality and safety.
