Lining a Chimney with Pummice Liners
Stove Help & Advice Home
It is also possible to line and insulate a chimney with stainless flexible chimney liner - click here for details of flexible liner.
The pummice chimney liners are lowered down from the top by a rope running beneath the first pummice 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.
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 pummice 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 pummice liner lowered down onto that from above.
Pummice chimney liners are available in sizes from 130mm to 1000mm, although the common ones used for stoves are 125mm, 150mm, 175mm and 200mm, along with 15*, 30* and 45* bends, access blocks, support blocks, adaptors etc
