What is Heat Insulation?
Insulation is defined as a material or combination of materials, which retard the flow of heat. The materials can be adapted to any size, shape or surface. A variety of finishes are used to protect the insulation from mechanical and environmental damage, and to enhance appearance.
Where is Mechnical Termal Insulation Installed?
Mechanical thermal insulations are materials that insulate the components of mechanical systems in commercial buildings and industrial processes.
In buildings such as shopping centers, schools, hospitals, and hotels, mechanical insulations are installed to improve the energy consumption of the buildings' cooling and heating systems, domestic hot and chilled water supply, and refrigerated systems including ducts and housings.
For industrial facilities, such as power plants, refineries, and paper mills, mechanical thermal insulations are installed to control heat gain or heat loss on process piping and equipment, steam and condensate distribution systems, boilers, smoke stacks, bag houses and precipitators, and storage tanks.
Substantial quantities of heat energy are wasted daily in industrial plants nationwide because of underinsulated, undermaintained or uninsulated heated and cooled surfaces.
Properly designed and installed insulation systems will immediately reduce the need for energy. Benefits to industry include enormous cost savings, improved productivity, and enhanced environmental quality.
By reducing heat loss or gain, insulation can help maintain process temperature to a pre-determined value or within a predetermined range. The insulation thickness must be sufficient to limit the heat transfer in a dynamic system or limit the temperature change, with time, in a static system. The need to provide time for owners to take remedial action in emergency situations in the event of loss of electrical power, or heat sources is a major reason for this action in a static systems.
Thermal insulation is one of the most effective means of protecting workers from second and third degree burns resulting from skin contact for more than 5 seconds with surfaces of hot piping and equipment operating at temperatures above 136.4F (ASTM C 1055). Insulation reduces the surface temperature of piping or equipment to a safer level as required by OSHA, resulting in increased worker safety and the avoidance of worker downtime due to injury.
Used in combination with other materials, insulation helps provide fire protection in:
- Firestop systems designed to provide an effective barrier against the spread of flame, smoke, and gases at penetrations of fire resistance rated assemblies by ducts, pipes, and cable.
- Electrical and communications conduit and cable protection.
Insulation materials can be used in the design of an assembly having a high sound transmission loss to be installed between the source and the surrounding area.
Grenhouse Gas Reduction
Thermal insulation for mechanical systems provides immediate reductions in CO2 , NOx and greenhouse gas emissions to the outdoor environment in flue or stack emissions by reducing fuel consumption required at the combustion sites because less heat is gained or lost by the system.
