Pumice is a natural insulator — the property that sets Isokern apart from other chimney materials. It lets flue gases reach optimum temperature quickly, helping your heating appliance perform at its best shortly after lighting, while keeping the chimney warmer for longer and reducing condensation and soot build-up. Schiedel Isokern is a well-established, CE-marked brand tested to the appropriate EN standards.
