Insulating Materials

An insulator in this context is something that has resistance to the transfer of heat. When two objects having different temperatures come into contact with each other, heat flow is almost immediate and inevitable. When an insulating material is placed between two heated objects, the result is a reduction of heat flow. Insulation materials have lots of different uses from human bodies to buildings to automotive engines for example.

The most important properties used to judge whether an insulating material is effective or not are as follows:

  • Low Thermal Conductivity
  • Surface Emissivity
  • Density
  • Thermal Bridging
  • Heat Capacity
  • Thickness of Insulation

These properties improve the function of the insulating material and heighten its performance. Other external environmental factors such as weather conditions, like humidity and so on also affect the way the insulating material works. When buying an insulating material for industrial usage, you need to make sure that the layers are strong enough and that the product has the required capability to withstand heat. Some industrial applications state that a specific insulation thickness is mandatory to proper functioning.

The most important advantage of insulating materials when used industrially is that they can distribute the heat evenly as well as reduce the overall energy consumption. In some cases a reduction of noise and vibration is also achieved if the appropriate insulting material is used. If the temperature is maintained on an even basis in an industrial situation and the energy is used as and when required, then the overall cost can be kept low, and impact on the environment can be kept in balance. In certain applications such as in the fish holds, the absorption of moisture needs to be done by the insulating materials. A good insulating material should be resistant to solvents and chemicals.

Ceramic fibre materials and vermiculite materials are the most commonly used insulating materials. They possess some of the most sought after qualities for insulation materials, including low thermal conductivity, thermal shock resistance and sound absorption. The ceramic fibre insulating materials provide insulation up to temperatures of 1400 °C. However, one important aspect to remember is that vermiculite boards are stronger than ceramic fibre boards. When it comes to ceramic insulating materials, substances like boards, modules, blankets and papers are widely used.

In an industrial situation, the failure of insulating material to work can result in disaster and this highlights the importance of the quality and choice of the correct material for the correct application. The type of raw material used, the process involved in manufacturing the materials and the labour force all contribute to the production of high quality insulating material.

At Vitcas, the focus is not only on the quality of the end product, but also on the raw materials used and workmanship involved. Manufacturing insulating products that last long, have durability and the appropriate thickness needs expertise and experience, all of which you can find at Vitcas.
