Isokern Pumice

 Naturally Insulated Chimney Systems

High Insulation Properties and Lightweight – 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.
