Pumice is a natural insulator; this is the unique property that separates pumice from all other chimney material. Schiedel Isokern is noteworthy for its flue & chimney products manufactured using high quality pumice which is recognised throughout Europe and USA.
The Natural properties of Pumice
- High Insulation Properties – Pumice is a natural insulator, able to maintain the temperature of flue gases in comparison to other products which allow the temperature to fall.
- Lightweight – Pumice is strong yet lightweight allowing one person to lift and build the chimney units.
- Resistant to temperature change – Pumice expands and contracts less with temperature change than other chimney systems. This reduces the possibility of cracking and structural damage that can occur with other products.
