Our DM44 180mm ID x 150mm high offset block is a top-tier component in the Isokern DM block system range. This double-module system is expertly engineered to maintain optimal flue gas temperatures while preventing heat transfer to the outer casing. These features help reduce the risk of cracks, leaks, and stains, ensuring a robust and reliable chimney setup.
The system's design facilitates quick and simple assembly, with three distinct outer casing sizes available: DM36, DM44, and DM54. Crafted from pumice, a natural insulator, the DM blocks ensure your chimney quickly attains the ideal temperature, maintaining performance and reducing the likelihood of condensation and soot buildup. Ideal for use with wood-burning stoves, open fires, inserts, and cookers using solid fuel, oil, or gas (excluding condensing appliances such as Biomass and Pellets).
The Isokern DM system holds HETAS approval and CE marking, affirming its quality and safety standards. For installation, refer to the included guidelines for best results.
