Z Blok


 Faster insulation
 Reduced shrinkage compared to layered lining.
 Low heat storage
 Superior to thermal stability and shock resistance.
 The resilient blanket is resistant to mechanical damage
 It is versatile and the modules can easily be cut, on the site to suit awkward configurations

Z-Blok refractory fibre modules are lightweight, insulating linings made in block form for direct attachment to industrial furnace and kiln shells. Z-Blok Modules are made from high quality needled Blanket, pre-compressed to a specific density, and held in position with stainless steel reinforcement and mounting hardware made up of beams positioned within the folds and connected by tabs to a channel on the cold face of the Z- Blok . These prefabricated modules are designed to meet the thermal insulation requirements of high temperature furnaces.
During installation, the modules are further compressed, the resilience of the fibre and recovery ensuring tightly-compressed inter-modular joints.
