The DM36 - 570mm square corbel for brickwork is part of the renowned Isokern DM block system, known for its high quality and efficiency. This double wall system ensures flue gas temperatures are maintained while reducing heat transfer to the outer casing, thanks to its innovative separation of inner and outer components. This feature allows for thermal movement, significantly reducing the risk of cracking, leaks, and stains.
Constructed from natural pumice, a superb insulator, the DM36 allows flue gases to quickly reach optimal temperatures, improving appliance performance and reducing the buildup of soot and condensation. The product is available in three outer casing sizes: DM36, DM44, and DM54, and is compatible with a variety of heating appliances.
