​Eco-Friendliness & Energy Efficiency

The protection of the environment, people, and processes against high temperatures requires highly durable and consistent materials implemented in optimally integrated systems. To maintain the thermal resistance of linings, both full and partial configurations utilize refractory insulation and sealing materials supplied in various shapes, consistencies, volumes, and modules, covering a broad range of thermal resistance demands in high-energy industrial processes. The goal of refractory insulation systems is to optimize energy consumption, reduce emissions, and lower operational costs.

​Phosphate-Bonded Monolithics

​Bonded with phosphate binders, providing exceptional resistance to molten metals and slags. Available in ramming, castable, and gunning mixes.

​Dry Vibratable Monolithics

​Self-leveling and consolidated by vibration, forming a dense lining that sinters into a solid layer after heating.

​Cements & Mortars

​​Pre-mixed dry or wet formulations, used for bonding bricks or fiber modules in rigid linings.

​These materials cover a wide range of industrial needs, ensuring resistance to high temperatures, mechanical stress, corrosion, and abrasion.
