Insulation Mortar

Insulation Mortar is a specialized jointing and bedding compound formulated specifically for use with lightweight insulation bricks and backup refractory linings. Standard dense mortars are unsuitable for insulation brick construction — their high thermal conductivity creates thermal bridges at every joint, undermining the insulating efficiency of the brick itself. Imperial World Trade supplies insulation mortars with thermal conductivity values matched to the brick grades they bond, ensuring a thermally consistent, joint-free lining system from hot face to cold face.

  • Thermally Matched Formulation: Conductivity values aligned with companion insulation brick grades to eliminate thermal bridging at joints.
  • Lightweight Composition: Low-density mortar preserves the overall weight advantage of insulation brick lining systems.
  • Air Setting & Heat Setting Grades: Available in both types to suit new construction and repair application requirements.
  • Strong Adhesion: Develops reliable bond strength with HFK, cold face, and calcium silicate insulation surfaces.
  • Easy Application: Smooth, consistent paste consistency allows thin, uniform joint application with standard masonry tools.
  • Temperature Rating: Available in grades suitable for service from 900°C up to 1,400°C depending on the insulation system specified.

Using the correct insulation mortar is as critical as selecting the right insulation brick. Imperial World Trade ensures that every mortar recommendation is thermally and chemically matched to your specific brick grade, delivering a complete, optimized insulation system rather than individual components in isolation.
