The DM44 - 570mm square capping for render is a part of the advanced Isokern Double Module (DM) block system, a premium solution in chimney technology. This system boasts a double-wall structure designed to efficiently maintain flue gas temperatures while preventing unwanted heat transfer to the outer casing. The separation of inner and outer components allows for thermal movement, reducing the risk of cracking and subsequent leaks or stains.
Perfect for stoves, open fires, cookers, and various heating appliances fueled by wood, solid fuel, oil, or gas (note: not suitable for condensing appliances including biomass and pellets). Constructed from pumice, a natural insulator, it ensures rapid attainment of optimal flue gas temperatures and prolonged warmth, boosting the performance of your heating appliance and minimizing condensation and soot buildup. The DM44 system stands out with its HETAS approval and CE marking, ensuring top-tier quality and safety.
Available in outer casing sizes DM36, DM44, and DM54, this chimney system is simple and quick to install, making it a favorite among both residential and trade clients.
