The DM44 - 740 x 740mm T corbel for external brickwork is an essential component in the Isokern DM block system. The double module system combines a sturdy outer casing with a high-quality pumice flue that maintains optimal flue gas temperatures. This design prevents heat transference and accommodates thermal movement, reducing the risk of cracks, leaks, or stains.

Isokern DM is CE marked and HETAS approved, ensuring you are getting a product that meets high safety and efficiency standards. This chimney system is versatile, suitable for use with wood, solid fuel, oil, and gas appliances, though not for condensing appliances like Biomass or Pellets. The pumice material acts as a natural insulator, quickly reaching optimal temperature and retaining heat longer, which improves performance and minimises condensation and soot build-up.

Installation is straightforward, guided by our detailed instructions.
