The DM36 - 490mm square capping for render is an essential component in our Isokern DM block system, celebrated for its high quality and performance. This innovative double wall system is designed to maintain flue gas temperatures effectively while preventing heat transference to the outer casing. The separation of inner and outer components allows for thermal movement, reducing the risk of cracking and potential leaks.
Suitable for a variety of heating appliances including inserts, stoves, open fires, and cookers burning wood, solid fuel, oil, or gas (excluding condensing appliances like Biomass & Pellets), this capping ensures longevity and efficiency of your chimney. Pumice, a natural insulator, enables the flue gases to quickly reach their optimum temperature, enhancing appliance performance shortly after ignition. Additionally, its insulation properties keep the chimney warmer for longer periods, decreasing condensation and soot build-up.
The Isokern DM system is HETAS Approved and CE marked, adhering to the highest safety and quality standards. Installation is straightforward, with comprehensive guides available to assist.
