Insulation materials: industry outline

The insulation industry plays a significant role in overcoming challenges related to energy consumption and sustainable construction. Effective insulation materials can contribute significantly to energy savings and CO2 emissions.

Various types of insulation materials are produced, such as glass wool, rock wool, polystyrene (EPS and XPS), polyurethane foam (PUR and PIR), wood fiber, cellular glass and also natural insulation materials such as hemp, sheep's wool and cellulose. The increased demand for sustainable construction has led to the use of more insulation materials.  

Insulation materials such as rock wool is produced by fusing stone, limestone and recycled bricks with other raw materials at approx. 1,500 °C. Binding and impregnating agents are added. The industry requires high-performance exhaust air purification systems in order to clean the exhaust air produced economically.

Typical pollutants

  • Carbon monoxide (CO)
  • Hydrogen sulphide (H2S)
  • Organic sulphur compounds
  • Sulphur oxides (SOx)
  • Dust
  • Halogens

Typical technical challenges

The use of natural materials such as stone and coal result in considerable dust formation and high fluctuations in concentration. Considerable temperatures must be taken into account in this process, which are fed back into the process by downstream heat recovery where possible.

In addition, corrosion resistance must also be ensured.

Typical solutions

As a general rule, combustion chambers with highly efficient heat exchangers are used to preheat the blast air for the cupola furnace, among other things. Spark separators, filter systems, DeSOx systems and multi-stage heat exchangers are used as well.
