Fibreglass and Rockwool

Fibreglass and Rockwool
Fibreglass is made from melted glass spun at high speed to create fibres. Rockwool (also called mineral wool) is created in the same way, using melted rock. Both have excellent insulation properties.

Aside from different starting ingredients, the production process for fibreglass and rockwool is the same. Temperature measurements at key points in the process support improved efficiency and quality control.

Making accurate temperature measurements at key locations in the production process helps control the quality of the finished fibreglass or rockwool product. AMETEK Land has a range of advanced, high-precision instruments, some specifically designed for the glass industry, to produce the required results, supporting quality control, process efficiency, and safety.
  • Applications +

    • Batch Inlet
      Batch Inlet

      Measurement at the batch inlet provides thermal monitoring of the glass raw materials for quality control. We recommend the LWIR-640 thermal imager or RT8 thermometer for this application.

    • Melt Tank - Outside
      Melt Tank - Outside

      An LWIR-640 thermal imager is recommended for continuous monitoring of the melt tank exterior. This monitors the tank condition, providing warnings of possible glass break-out or refractory failure.
