Benefits of Insulation

Thermal insulation is one of the most effective means of protecting workers, resulting in increased worker safety.


Benefits of Insulation:

  • Reduces energy costs
  • Prevents moisture condensation
  • Reduces capacity and size of new mechanical equipment
  • Enhances process performance
  • Reduces emissions of pollutants
  • Safety and protection of personnel
  • Acoustical performance: reduces noise levels
  • Maximizes return on investment (ROI)
  • Improves Appearance
  • Fire Protection

Health and Safety

A well-designed and insulated system will protect personnel by:

  • Lowering hot surface temperatures
  • Preventing accidental burns

Thermal insulation is one of the most effective means of protecting workers from burns resulting from contact with hot or extremely cold piping and equipment. For hot surfaces, especially, insulation reduces the surface temperature of piping or equipment to a safer level, resulting in increased worker safety and the avoidance of worker downtime due to injury. With today’s specification tools it’s very easy to calculate the insulation thickness needed to bring the surface temperature of your piping and equipment to safe levels.

In addition to the safety benefits of insulation, NIA member companies take job site safety very seriously and strive to meet the highest standards to protect their own personnel.

Mechanical Insulation Life Cycle Assessment

Mechanical insulation saves up to 500 times the energy and 750 times the emissions required for its production.

Mechanical insulation and insulation in general are among the few industrially manufactured products that save more energy over their life span than is required for their manufacturing. The National Insulation Association (NIA) has estimated that mechanical insulation systems, compared to surfaces without insulation, save more than 140 and up to 500 times more energy over their life spans (20 years for the purposes of this discussion) than it takes to produce them. Mechanical insulation also saves a minimum of 150 (and up to 750) times more CO2 emissions than it takes to produce the insulation product. This data proves beyond doubt that mechanical insulation is a

Mechanical insulation systems are used for piping, equipment, vessels, ducts, boilers, and similar mechanical equipment in commercial building and industrial applications. They perform thermal, acoustical, and personnel safety functions for piping and equipment in both hot and cold applications; Heating, Ventilation, and Air Conditioning (HVAC) applications; and refrigeration and other low-temperature piping and equipment applications.

Insulation reduces energy consumption and greenhouse gas emissions. Properly installed and maintained insulation can also:

  • be an important part of sustainable design initiatives and safety programs
  • increase available carbon credits
  • increase manufacturing productivity
  • eliminate or reduce corrosion under insulation
  • control condensation and mold growth
  • provide an unrivaled return on investment

From a life cycle perspective, insulation is one of the most sustainable green initiatives in the industrial and commercial building sectors.

A life cycle assessment (LCA) is used to systematically investigate the environmental impact of goods. The complete life cycle of a product is tracked “from cradle to grave.” All aspects of the product’s life, including raw material production, energy usage, manufacturing, transporting, use, and disposal, are considered. Such ecobalances provide information on greenhouse gas emissions and the use of energy and raw materials, which is becoming increasingly important.

Construction and operation of commercial buildings and industrial facilities are among the most energy- and raw material-intensive industries. To meet the growing need for energy and protect the environment for future generations, increased energy efficiency/conservation should be considered a primary source for reducing energy use and emissions. Mechanical insulation is one of the most valuable keys to achieving those goals. It is relatively simple, cost effective, maintainable, and “shovel ready,” creating and preserving jobs now on a local basis across a wide array of industries. It’s time to get excited about mechanical insulation.
