The DM36 Chimney Flue System, featuring a 360mm square casing x 250mm high, is a leading solution in the market for anyone seeking a robust and efficient chimney system. This high-quality double module Isokern DM block system is designed to maintain optimal flue gas temperatures while preventing heat from transferring to the outer casing. The unique double wall system allows for independent thermal movement, significantly reducing the risk of cracking and subsequent leaks or stains.
Constructed from pumice, a natural insulator, the DM36 provides unparalleled thermal properties. It enables the flue gases to quickly reach optimal operating temperatures, enhancing the performance of your heating appliance. The insulation also keeps the chimney warmer for longer periods, reducing condensation and soot buildup.
Perfect for use with wood, solid fuel, oil, and gas (excluding condensing appliances like biomass and pellets), the DM36 is HETAS approved and CE marked, making it a reliable choice for any home or business. Installation is straightforward, and the system is available in three outer casing sizes: DM36, DM44, and DM54.
