Piping plays a central role in many industrial processes in chemical or petrochemical installations such as power plants, as it connects core components such as appliances, columns, vessels, boilers, turbines etc. with one another and facilitates the flow of materials and energy.

The importance of insulation

The basic efficiency and productivity factors of piping for the processing industry include energy efficiency, dependability and reliability under different conditions, in addition to the functionality of the process control, an appropriate structure that is suitable for the operating environment, as well as mechanical durability. The thermal insulation of piping plays a significant role in fulfilling these requirements.

Purpose of insulation

The functions of correct thermal insulation for piping include:

  • Reduction of heat losses
  • Cost savings
  • Reduction of CO2 emissions
  • Frost protection
  • Process control: ensuring the stability of the process temperature
  • Noise reduction
  • Condensation prevention
  • (Personal) Protection against high temperatures
Selection of pipe insulation

Generally, the best insulation is achieved using ROCKWOOL pipe sections. The sections are quick and easy to install. Their excellent fit and high compression resistant means pipe sections can be applied in a single layer without any additional spacers. They also have a lower insulation thickness.


Load‑bearing mats, such as ProRox MA 520 ALU are applied in situations where the use of pipe sections is more difficult. ProRox wired mats are applied in situations where it is difficult or impossible to use pipe sections or load bearing mats. Note: Pipe sections and load-bearing mats offer the advantage that spacers are generally not required. Pipe sections and load bearing mats are applied more quickly without the interference of spacers.

The ROCKWOOL Group has launched a new Sustainability Report highlighting its approach to sustainability
