The DM44 outer casing is a key component in the Isokern Double Module (DM) block system, renowned for its high quality and exceptional performance. This advanced double wall system efficiently maintains flue gas temperatures and prevents heat transference to the outer casing. The innovative separation of inner and outer components supports thermal movement, significantly reducing the risk of cracking, leaking, or staining.
The DM44 is part of a system available in three sizes—DM36, DM44, and DM54—offering versatile options for various applications. Constructed from natural pumice, a superb insulator, the DM44 outer casing ensures flue gases reach optimum temperature quickly, enhancing the heating appliance's performance soon after ignition. It also retains heat effectively as appliance output decreases, reducing condensation and soot build-up.
Compatible with inserts, stoves, open fires, and cookers using wood, solid fuel, oil, or gas (excluding condensing appliances like Biomass and Pellets), this product is versatile and reliable. Fully approved by HETAS and CE marked, the Isokern DM system promises compliance with stringent safety and performance standards. For precise installation, refer to the provided installation guides.
