DM Systems When ease of construction and maximum insulation matter, the Double Module System comes into its own. This chimney system is 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. The Pumice chimney systems are suitable for wood logs, solid fuel, oil and gas (not suitable for condensing appliances)
Liner Systems The pumice liner system comes in a range of 15 diameters from 150mm to 1000mm internal diameter. The Pumice flue liners are for masonry chimneys where the linings are surrounded by 100mm of brick, block or stone. The linings are suitable for all fuels but not suitable for condensing appliances –including pellet or biomass. Pumice liners are ideal for new build as well as relining existing masonry chimneys.
