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).
Wood burning stoves
Stove inserts
Solid fuel / oil cookers
Open fires
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.
Pumice has very little expansion and contraction with temperature change. This reduces the possibility of cracking and structural damage.
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.
Pumice is strong yet lightweight allowing one person to lift and build the chimney units.
