The DM54 - 950mm square capping for brickwork is part of the superior Isokern DM block system, a high-quality double module chimney solution. Designed to maintain flue gas temperatures effectively, this system also prevents heat transference to the outer casing, thanks to its double wall construction. This advanced design allows for thermal movement, reducing the risk of cracks and potential leakages or stains.

Moreover, it is simple and quick to assemble, making installation a breeze. Available in three sizes—DM36, DM44, and DM54—this system is versatile and can be used with inserts, stoves, open fires, and cookers burning wood, solid fuel, oil, or gas (excluding condensing appliances like Biomass & Pellets). Pumice, a natural insulator used in the construction, ensures swift reaching of optimal flue gas temperatures, thus enhancing the performance of your heating appliance and reducing condensation and soot build-up.

Approved by HETAS and CE marked, the Isokern DM system meets high standards with the designation number T450 N1 D 3 G(00). Detailed installation instructions are provided in accompanying guides.
