Reducing Heat Loss with Lightweight Insulation Spray Coatings

Lightweight insulation spray coatings use low-density aggregates to improve thermal efficiency without placing excessive load on furnace structures.

Key considerations

  • Use continuous sprayed layers to reduce joints and local heat leakage.
  • Confirm substrate preparation and anchoring requirements for the operating environment.
  • Assess energy performance together with shell temperature and long-term lining stability.

Application-focused decisions

Refractory selection should reflect the actual operating environment, installation method and maintenance objective. Temperature alone is not enough: chemical attack, abrasion, thermal cycling, mechanical impact and available repair time should be evaluated together.

Installation and inspection

Correct storage, mixing, surface preparation, installation and dry-out are essential to achieving the intended performance. Routine inspection data helps maintenance teams identify wear trends, schedule repairs and improve the lining strategy for future campaigns.
