Hot and humid weather is common in our country, so finding ways to reduce heat inside buildings has become essential. One of the most popular options is thermal insulation. Whether it’s a house, office building, or industrial factory, various types of insulation are installed to keep temperatures at an appropriate level. This article will introduce you to the types of insulation commonly found, along with suggestions for choosing the right one for the job and area.

What is thermal insulation?

Thermal insulation is a material that reduces the transfer of heat from outside into the building or from one area to another. It is suitable for controlling the temperature in areas that require consistent cooling and reduces energy use in air conditioning. The principle of thermal insulation is to reduce the conduction and radiation of heat, resulting in a decrease in the rate of heat transfer through walls, roofs, or other parts of the building.

Key properties of good thermal insulation

• The higher the thermal resistance value or R-Value, the better the thermal resistance capability.
• The lower the thermal conductivity value or K-Value, the lower the value, the less thermal conductivity it has.
• Light weight does not add too much weight to the building structure.
• Moisture resistant , not easily deteriorated when exposed to moisture
• Non-flammable, flame retardant, increases safety.
• Non-toxic , does not release toxins that are harmful to health.
• Easy to install , can be installed conveniently, not complicated.
• Long service life , maintains efficiency for a long period of time

Popular types of insulation

Each type of insulation has different properties and is suitable for different applications. Therefore, the choice depends on the purpose and installation area. Let’s see what types there are.

1. Rock wool insulation

Rock wool insulation is insulation made from basalt rock through a high-temperature melting process. It has outstanding fire resistance properties, is non-flammable, and does not react with metals. It can withstand heat exceeding 300 degrees Celsius, making it ideal for industrial applications requiring high safety.

2. Fiberglass insulation

Fiberglass insulation is made from fine glass fibers formed into sheets or rolls. Some types have foil lining to reflect heat. It can withstand heat up to 300 degrees Celsius. In addition to blocking heat, it also absorbs sound well. It is commonly installed on roof structures, ceilings, and walls. However, a caution is that it is not resistant to moisture. When wet, it loses its heat-insulating properties.

3. Polyurethane foam insulation

Polyurethane foam insulation is a fine-textured foam that can be sprayed into gaps to completely seal leaks. It reduces heat radiation through the roof by more than 90% and effectively protects against water and moisture. Therefore, it is ideal for factories or buildings with heat dissipation problems, including areas requiring seamless insulation.

4. Cellulose insulation

Cellulose insulation is made from recycled wood pulp or paper mixed with flame retardants for added safety. It comes in sheet, blanket, and spray-on fibers. It is inexpensive and environmentally friendly, making it ideal for use in walls or under roofs. However, it is not very resistant to water and humidity, so it should be installed in dry, well-ventilated areas.

5. Aluminum foil insulation

Aluminum foil insulation is a shiny, smooth, and durable aluminum foil that doesn’t tear easily. It works by reflecting heat radiation rather than blocking it directly. Therefore, it is often used in conjunction with other types of insulation to increase efficiency. It is commonly installed on the roof structure or exterior walls of buildings to reflect heat from the sun before it enters the building.

Benefits of thermal insulation

• Helps reduce heat entering the building, making the house cooler.
• Helps save on electricity bills by reducing air conditioning usage.
• Helps maintain a constant temperature inside the building.
• Some types of insulation can help reduce external noise.

Application of thermal insulation

Thermal insulation is a material that can be used in a variety of applications in buildings and homes, as follows:

1. Install roof insulation under the roof to protect against heat from direct sunlight.
2. Install insulation on the ceiling to prevent heat from accumulating under the roof.
3. Install wall insulation to reduce heat transfer through the walls.
4. Wrap hot water pipes or steam pipes in industrial plants to maintain temperature.
5. Used in the construction of cold rooms, production lines, or temperature-controlled rooms.

Thermal insulation is essential for modern buildings that face increasingly hot weather conditions. Choosing the right insulation for the application will increase heat protection efficiency, reduce energy costs, and create a pleasant environment within the building.
