Highland Refractory supplies high alumina lightweight bricks for protected insulation layers, backup linings and thermal barriers in industrial furnaces, kilns and high-temperature equipment. These lightweight refractory bricks combine an alumina-based composition with a low-density structure to help reduce heat transfer while maintaining the stability required by a supported insulation system.
The product series is intended for project buyers who need to coordinate insulation materials across cement, steel, glass, petrochemical, power and industrial heating equipment. The specific density grade, dimensions and physical properties are confirmed according to the equipment design and the applicable technical data sheet.

High alumina lightweight bricks are primarily used as backup linings, insulation layers and thermal barriers. Their low-density structure helps reduce heat transfer through the furnace wall and can reduce the thermal load transferred to the outer steel shell when the lining is properly designed and supported.
These bricks are not a universal replacement for dense working refractories. Areas exposed to severe abrasion, direct molten material contact, heavy impact or concentrated mechanical load require a separate working-lining assessment. In a multilayer system, dense refractory materials may protect the hot face while a high alumina lightweight insulation brick provides thermal resistance behind it.
The correct grade and construction depend on the equipment temperature, lining position, support condition, fixing method, atmosphere and required dimensions. For density, thermal conductivity, compressive strength and LG-grade data, visit the High Alumina Lightweight Brick technical detail page.
This series page provides a supply and application overview. It does not replace the product-specific technical data sheet or the lining design prepared for a particular furnace.
The high alumina lightweight brick series can be evaluated for protected insulation zones across different industrial heating systems. Application suitability depends on the actual operating conditions and the mechanical support available behind the working lining.
Potential use in protected preheater, calciner, shell-insulation and backup zones where heat-loss control is important and direct abrasive exposure is limited.
Used as a protected insulation layer behind dense refractory materials in reheating furnaces, soaking pits and related thermal equipment.
Can be evaluated for protected insulation areas where stable thermal performance is needed. It should not be treated as a substitute for AZS in direct molten-glass contact zones.
Potential use in protected backup insulation for reformers, incinerators, boilers and other high-temperature units after temperature, atmosphere and support conditions are reviewed.
Can support thermal barrier and insulation designs where low heat transfer and controlled material weight are part of the equipment requirements.
For every application, confirm the furnace type, lining position, operating temperature, atmosphere, support condition and required dimensions before selecting a specific LG grade.
Highland Refractory coordinates high alumina lightweight brick supply around the confirmed project specification. The series can be discussed for standard brick dimensions, custom shapes and equipment-specific insulation requirements, subject to the product grade and manufacturing scope.
Specification Coordination
Grade, target density, dimensions, shape, quantity and lining position are reviewed before production planning.
Standard & Custom Shapes
Standard bricks and project-specific wedge or shaped components can be coordinated from confirmed dimensions or drawings.
Project Material Coordination
Lightweight bricks can be evaluated together with related insulation materials when a project requires more than one refractory form.
TDS-Based Confirmation
The final LG grade and physical properties are confirmed against the applicable technical data sheet and agreed purchase specification.
For detailed LG-0.6 to LG-1.0 density, strength and thermal conductivity data, use the full technical detail page.
Lightweight refractory bricks require protection against edge impact, moisture and movement during handling. Packaging and delivery conditions are confirmed according to the grade, shape, order quantity and destination requirements.
