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 burning, solid fuel, oil and gas.
There are 3 systems covering a range of different internal diameters
to meet the requirements of different appliances and uses:
DM 36
150mm internal diameter for smaller output
inserts, stoves and solid fuel/oil cookers
DM 44
180mm and 200mm internal diameters for
inserts, stoves and open fires
DM 54
300mm and 345mm internal diameters for
Magnum firechests and larger appliances,
inserts and open fires
