Promasil® Insulation Boards are lightweight calcium silicate boards engineered for high-temperature thermal insulation and refractory backup lining applications. Combining low thermal conductivity, low heat storage and excellent mechanical strength, they provide an effective solution for improving thermal efficiency and reducing heat loss in industrial process equipment.
Designed for use behind dense and lightweight refractory linings, Promasil Boards deliver reliable thermal performance while reducing overall lining weight and improving furnace efficiency. Their stable mineral matrix structure provides excellent dimensional stability and long-term durability in demanding operating environments.
Available in multiple grades, densities and formats, including boards, pipe sections, segments and fabricated components, the Promasil range provides versatile insulation solutions for heavy industry, oil and gas processing and thermal manufacturing applications.
Promasil Boards are designed to maximise thermal efficiency while providing the strength and stability required for demanding industrial applications.
