When the ease of construction and maximum insulation matter then the Double Module System comes into its own. Isokern chimney systems are designed to be quick and easy to install. The lightweight blocks are easy to handle. The outer and inner blocks are laid at the same time but with staggered joints for safety and stability. The double layer of pumice separated by an air gap maximises the chimney insulation. BMF Creative Interiors are suppliers of Isokern chimney systems which are suitable for wood logs, solid fuel, oil and gas (not suitable for condensing appliances).
