DM system

DM

When the ease of construction and maximum insulation matter then the Double Module (DM) System comes into its own. This chimney system is designed to be quick and easy to install. 

Product details

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).

  •  Zero distance to combustibles on straight rendered chimneys (when using top ring terminal)
  • Quick and easy to assemble
  • Lightweight materials, easy to handle
  • Highly insulating pumice for better draw and minimum heat loss
  • Staggered joints for maximum safety and stability
  • Air gaps between outer casing and flue prevents surface staining
  • Good resistance to temperature variations gives the maximum performance for your appliance.
  • CE Certified to EN1858 with the designation T450, NI, D, 3, G (00).

Natural volcanic pumice

Pumice is a natural insulator. This is the unique property that separates pumice from all other chimney materials. The insulating properties of Pumice allow the flue gases in the chimney to quickly reach their optimum temperature enabling the heating appliance to reach its optimum performance shortly after lighting.


It also keeps the chimney warmer longer as the heat output of the appliance decreases – once again aiding performance and reducing the likelihood of condensation and soot build-up.

RESISTANT TO TEMPERATURE CHANGE

Pumice has very little expansion and contraction with temperature change. This reduces the possibility of cracking and structural damage.

HIGH INSULATION PROPERTIES

Pumice is a natural insulator, able to maintain the temperature of flue gases when other products have allowed the temperature to fall below the dew point.

LIGHTWEIGHT

Pumice is strong yet lightweight allowing one person to lift and build the chimney units.
