Lining a chimney with pumice chimney liner

Pumice chimney liners provide a permanent masonary insulated chimney. We can supply pumice chimney liners and pre-formed chimney sections, both for new build chimneys and for re-lining existing chimneys. For your interest and to avoid confusion it is worth noting that pumice is often misspelt as 'pummice'.

For prices of our pumice liners see our Pumice chimney liner prices page.

Method for relining existing chimneys with pumice liners

pummice chimney liners uk The pumice chimney liners are lowered down from the top by a rope running beneath the first pumice liner. As it is lowered each 600mm length is jointed to the next using lip glue and steel collars. When the first pummice liner reaches the gather or support block at the bottom the rope is removed and the cavity is back filled using a 20:1 mix of leca chimney insulation and cement.

pummice chimney liners uk If there is a bend in the chimney then a hole is made in the chimney wall at that point, the first straight lengths of pumice liner are lowered down through that hole until that point is reached, then an offset is positioned and the rest of the straight sections of pumice liner lowered down onto that from above.
