High-Temperature Thermal Insulation

In large industrial projects that use high-temperature thermal energy, such as power plants, metal foundries, or sugar mills, these facilities calculate energy value as a cost. If some energy is lost, it increases costs, similar to an opportunity cost.

This year, we have all seen clean energy as a rapidly growing trend, including electric vehicles, wind power plants, and biomass power plants. These industries are rapidly expanding their production capacity, resulting in the construction industry growing as well.

What is high-temperature insulation?

High-temperature insulation is thermal insulation that can withstand high temperatures for extended periods while maintaining its insulating properties. We apply thermal insulation for two reasons:

  1. To maintain the temperature of internal materials and save energy (Energy saving)
  2. To protect humans from contact with heat (Personal Protection)

Calcium silicate insulation is characterized as calcium cement cast into sheets and pipes, with temperature resistance up to 650°C

  • Sheet-type calcium silicate is characterized as rigid sheets measuring 30 cm wide and 60 cm long
  • Pipe-type calcium silicate is characterized as pipes according to IPS steel pipe sizes, 60 cm long per section

** Currently, it is popular to switch to using ROCKWOOL stone wool insulation instead because the operating temperature is the same and it is easier to work with
