The DM44 - 820mm Square Capping for Brickwork is a top-tier component of the Isokern DM block system, renowned for its high-quality construction and performance. The double module (DM) design ensures that flue gas temperatures are maintained, while preventing heat transference to the outer casing. This is crucial for protecting your chimney and promoting longevity.

The innovative separation between inner and outer walls allows for thermal movement, a clever feature that reduces the risk of cracking, leakage, or staining. This system is quick and simple to install and is available in three sizes: DM36, DM44, and DM54. Not limited by the type of appliance it supports, the DM system is perfect for inserts, stoves, open fires, and cookers that use wood, solid fuel, oil, or gas (excluding condensing appliances such as Biomass and Pellet systems).

The unique insulating properties of pumice, a natural heat insulator, allow the flue gases to rapidly reach optimal temperatures, enabling better performance from your heating appliance. This feature keeps the chimney warmer for longer, reducing condensation and the build-up of soot. The Isokern DM system is HETAS-approved and CE marked, ensuring it meets the highest standards.

Installation is straightforward with detailed guides available for your ease.
