DM DOUBLE MODULE CHIMNEY SYSTEM

When the ease of construction and maximum insulation matter then the Double Module System comes into its own. The 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 blocks separated by an air gap maximises the chimney insulation.

The Pumice Systems are suitable for wood - logs, pellets and chips, solid fuel, oil and gas.

There are 3 systems in different internal diameters to meet the requirements of different appliances and uses:

  • DM 36, 150mm internal diameter for smaller output inserts, stoves, pellet boilers and cookers
  • DM 44, 180mm, 200mm and 225mm internal diameters for inserts, stoves and open fires
  • DM 54, 300mm and 345mm internal diameters for Manor firechests and larger appliances - inserts and open fires


The diameter of the appliance outlet determines the diameter of the chimney required.
