Lightweight Pumice Chimney Blocks ~ these are suitable as a flue
system for solid fuels, gas and oil. The highly insulative properties
provide low condensation risk, easy installation as a supplement to
existing or on-going construction and suitability for use with
timber frame and thatched dwellings, where fire safety is of
paramount importance. Also, the natural resistance of pumice to
acid and sulphurous smoke corrosion requires no further treatment
or special lining. A range of manufacturer's accessories allow for
internal use with lintel support over an open fire or stove, or as
an external structure supported on its own foundation. Whether
internal or external, the units are not bonded in, but supported on
purpose made ties at a maximum of 2 metre intervals.
