The Isokern chimney is manufactured as modular refractory masonry components designed for field assembly. The components consist of interlocking pre-cast parts which fit together using a temperature resistant mortar supplied with the units. The system includes all parts necessary for assembly of a complete chimney system. The parts of the system are cast using a proprietary mixture of volcanic pumice aggregate and Aluminate cement. Each piece is designed for a specific part of the chimney and is designed as such that only one means for complete assembly is possible.
Two separate types of components are used for various areas of the chimney system; a high density/high temperature flue liner and a medium density/high temperature insulating firebox/smoke dome/chimney outer block material.
The chimney is assembled on site following the manufacturer's written and illustrated instructions. A suitable foundation provided for installation of the Isokern components. Tongue and groove type construction of the chimney components assures proper alignment and tight joints. Premixed mortar (dry) is provided with the chimney system and is used at all joints between pieces.
