The DM36 - 690mm Square Capping for Brickwork is a crucial component of the high-quality Isokern DM block chimney system. This double wall system is meticulously designed to maintain flue gas temperatures while insulating against heat transference to the outer casing. The separation between inner and outer layers enables necessary thermal movement, effectively mitigating risks of cracking, leaking, or staining.

The DM36, along with its counterparts DM44 and DM54, can be effortlessly constructed and is suitable for a range of heating appliances, including inserts, stoves, open fires, and cookers that burn wood, solid fuel, oil, or gas (excluding condensing appliances and Biomass & Pellets). Made from pumice, a natural insulator, the DM36 allows quick attainment of optimal flue gas temperatures, enhancing the efficiency of your heating appliance soon after lighting. As the appliance cools, the pumice insulation maintains a warmer chimney longer, thereby reducing condensation and soot build-up.

This Isokern DM system is HETAS approved and CE marked, ensuring top-notch reliability and safety. Please refer to the included installation guides for detailed instructions.
