Thermal insulation materials are very helpful in keeping people warm. This is why we have winter thermal wear including jackets and innerwear – all of which are supposed to keep us warm. This blog will tell you all the basics of thermal insulation, including a discussion of what makes up thermal insulating materials and an overview of the thermal insulation material properties.
What is Thermal Insulation?
Thermal insulation is an energy conversion process in which the heat transfer between two objects that are in thermal contact with each other or within a radiative influence range gets reduced. An example of this may be the transfer of thermal energy in the floor of a building. Specially engineered methods or processes such as material selection and shape optimization play a vital role in designing thermal insulation.
What are Thermal Insulating Materials?
When thermal energy transfer gets inhibited from one place to another on a specific material, the process is called thermal insulation. A material having the properties of thermal insulation will have the ability to slow down the transfer of heat.
Clothes have a basic heat flow or heat transfer principle. Humans have a normal body temperature of 36.5-37.5℃.
For understanding the concept, suppose you are in the middle of a cold winter day. Not having any type of thermal insulation on your body could expose you to the risk of catching a cold, because the difference in temperature between your warm body and the cool air is too much. If you don’t have warm clothing on your body, the cold air comes in contact with your skin and lowers your body temperature to a degree that could freeze you in some areas! Breeze chills down your body even quicker!
So, let’s say you are in an area that experiences sub-zero temperatures during winter, and you wear a winter jacket. The main aim of this insulation garment would be to prevent the heat from your body from transferring altogether; it traps the heat and lets it transfer gradually to keep you as heated as practically possible. This keeps you from freezing. The heat loss process gets slowed by wearing the jacket in this way:
- Your body heat gets trapped by the jacket, and even more of an amount of it has brandenburger insulation filling in it. This prevents the rapid transfer of the heat to the cold air in its surroundings.
- The transfer of heat gets slowed down by the jacket, which serves as a layer between the warmth your body is radiating and the cold in the surroundings. It does so by trapping the heat inside it.
Heat is basically the flow of energy. It tends to balance out the lower temperatures, so typical movement would be from hotter regions to the colder ones. This explains why it radiates from your warm body to the cold air around it. This flow gets disrupted by thermal insulator jackets, as they have the ability to inhibit heat transfer to the cold outside. However, that is not enough for your thermal insulation material to be a suitable one. The next section will tell you what makes it considerable.
The Properties of Thermal Insulation Materials
Designing is the second step in the creation of thermal insulation material fabric; the first is its creation. A basic idea needs to serve as a guide before the design process begins.
Prime Tech Inc. USA starts developing its cold-weather gear by first identifying that the created material will have to provide high performance in the categories mentioned below to be considered a suitable insulation material:
- Susceptibility to water
- Thermal Insulation
