DM pumice chimney system
DM pumice liner is a modular block system and is a little like concrete lego (also Danish!). DM system is comprised of pumice inner liners and then a lightweight square concrete outer casing. They are glued together using lip glue and the outer casing normally jointed with sand cement mortar (the liner joints and block joints are staggered for strength). This forms the smallest masonry chimney possible. So what's so good about the DM pumice chimney system?
- The DM Pumice chimney system is very fast to install so whilst the material costs may be a little higher than alternatives the labour cost is far less.
- DM forms a chimney with a very low footprint, taking up less valuable space in the house.
- Non structural timbers can be run right up to the external face of the chimney.
- Making an airtight seal at the roof penetration is relatively easy.
- DM forms a very well insulated chimney suitable for an efficient woodburning stove - clay and concrete liners are not really a suitable chimney for a wood stove, whatever people may tell you.
- A DM pumice chimney can withstand the high temperatures of a chimney fire.
