coating system is especially suited to older properties, the chimneys
of which have usually suffered from the ravages of time and use. We
use a mix of fibreglass strand reinforced, crushed firebrick based
aggregate mixed with a high quality lime putty. This maintains the
essential flexibility in a lime built structure, as well as allowing
any moisture present to be evaporated up the chimney.
sweeping and/or chain flailing to remove loose material, the mix is
poured on to a former which is winched through the chimney, forcing
the new parging on under pressure. The larger gather area above the
fireplace has to be done by hand.
have been using this system for 20 years and it has proved to be very
possible, we would install Isokern pumice liners because of their
inherent safety factor. However, most open fires have a chimney
correctly sized for the fireplace opening. making it impossible to
install any suitable liner without drastic structural works. Unlike a
closed appliance, an open fire sends plenty of heat and air up the
chimney so an insulated liner is not essential. In fact, heat
recovery from a warm chimney breast is often regarded as an important
benefit. The critical factor is a sealed chimney creating the
necessary vacuum for the smoke to exit the top of the chimney and not
wander off to where it is not wanted!
