Why Is Thermal Insulation So Important to Save Energy?

Electricity bills are soaring! Struggling to control the heat – loss or gain – of your space i.e. industry or house? The probable solution lies in thermal insulation, which you might have ignored, or the existing one needs to replace.

So why is thermal insulation so prevalent, irrespective of energy-saving and temperature control. Let’s dig deeper…

What is Thermal Insulation?

It is an engineering process by which the reduction of heat transfer from one object to another is achieved. It’s a study of thermodynamics and covers various issues in controlling and managing the temperature of different environments. The process slows down the heat flow.

In house or any other industrial purpose, sometimes we need thermal protection or heat resistance to manipulate the temperature in our favour. Thermal insulation is one of those ways to do that.

In basic understanding, thermal insulation engineering stops the passing of the extra heat between the objects.

A practical example of a thermal insulator is a stainless steel hot water-keeping bottle. Inside the bottle core, there are layers in between the exterior and the center of the bottle.

You can test the heat resistance capability of the bottle by touching the exterior part. If you feel less heat, it means the bottle’s core works as an insulator keeping the water warm.

Natural Thermal Insulator

Different kinds of natural thermal insulators are available. They can be animal-based insulators, plant-based insulators, mineral-based insulators. An example of an animal-based insulator can be the polar bear.

Types of Material Used for Thermal Insulation

Different industrial materials are used for thermal insulation. The most common are Fiberglass, Mineral Wool, Cellulose, Polyurethane Foam.

There are particular tiles, known as heat resistant tiles, used for a space mission and space ship or space engineering.

How does it work?

It is generally a process of heat transmission. The heat is transferred, maintaining conduction, convection, and radiation. And sometimes, the insulation can be a combination of three.

A thermal insulator can be used inside of the object and also outside of it. As we see, some of the best exterior thermal insulators (cea mai buna izolatie termica exterioara) are used in the plain or other passenger transport for regulating the sun’s heat and maintaining the inside temperature of the plane.

With the increasing energy consumption rate and fossil fuel burning, thermal insulation use for domestic purposes has increased.

Benefits of Using a Thermal Insulation

There are different types of thermal insulation used for a variety of home and industrial purposes. The environmental and ecological impact of the use of thermal insulation is so vital.

Here are some benefits of adding thermal insulations to your construction:

Help in Fighting Global Warming

We generally use electric heaters or burn logs to keep the warmth of the house in the winter and use air conditioning to neutralize the room temperature in the summer. It causes more energy loss and triggers climate-related issues.

The greenhouse and climate change are causing severe damage to the earth’s life and the environment, increasing the heat in the atmosphere. The proper and maintained use of thermal insulation can be a preventive measure against climate change.

Ensure a Comfortable Living Environment

Using thermal insulation for domestic purposes keeps the room temperature cozy. It also helps to reduce noise pollution. Further, it can reduce the cost of your extra heating and cooling.

Moreover, inside a structure, it prevents and reduces the movements of the heat and condensation of the vapour. Eventually, it masks a design more lasting.

Save Energy

At this hour of the global energy crisis and global warming, the implementation of thermal insulation would be an excellent solution – saving energy and immission of carbon dioxide.

Using thermal insulation, you don’t need to burn or require any other fossil fuel to adjust the temperature during different environments and seasons.

Adding thermal insulation to buildings’ walls and the roof can effectively improve the inside temperature.

An example of the most widely used thermal insulation is in a commercial plane’s body. The insulation stops entering the heat of the sun or heat of the atmosphere inside the plane, for which the aircraft can balance its internal heat.

With the proper use of the engineering application of thermal insulation in the building, you can significantly reduce the energy cost by up to 40 to 50 percent.


With different types of use, it is essential to know that thermal insulation is the engineering method of heat resistance and lower energy consumption. It can reduce the whole energy consumption required to condition the temperature of an environment. So if you want to save energy and increase the efficiency of a thermal control system, consider adding thermal insulation.
