What is the thermal insulation of a building?

Thermal insulation is used as a solution to prevent the transfer of heat and even sound in the walls, ceilings, floors, etc. of a house or any part of the building cover. Insulation is one of the most important and cost-effective construction materials. Insulation also significantly reduces energy consumption. When insulation is used in a residential, commercial, institutional, or industrial building, it provides an environment (cooler in summer and warmer in winter) for living and working. All this while reducing energy consumption. This is especially important considering the diverse and variable weather conditions around the world. In this article, the types, uses, features, benefits of thermal insulation, etc. are discussed, stay with us.

Types of thermal insulation

Insulators are generally divided into categories, stone wool sandwich panels, polystyrene sandwich panels, polyurethane sandwich panels, tubular insulation, and cellulose. Thermal insulations are:

Mineral fibers

Mineral fibers are made by crushing the granules of slow-melting fire-fighting rock. In addition to being non-flammable, this insulation is also a heat and sound insulation, which is used in the form of a light elastic mat or cover body to insulate sloping roofs on the underlying cover plates. Another notable feature of mineral fibers is to prevent the growth of fungus and mold and are odorless and moisture-wicking.

pearlite

This mineral is of volcanic origin and is mixed with a little water. Perlite is a type of volcanic rock that forms in humid areas. One of the characteristics of this stone, which made it used as thermal insulation, is its inorganic nature, which means that this insulation does not react with most acids and is resistant to decay and termite attack. Perlite has significant disadvantages and it should be noted when buying that the compressive strength of this insulation is low, so it should not be used in places under high pressure and humidity, and also due to the connection of its holes, it absorbs water like a sponge. It sucks and its resistance decreases.

glass wool

This material is prepared by blowing water vapor on fibers made of molten glass. Its specific mass is between 8 and 140 kg/m3 and its maximum working temperature is 600 degrees Celsius. Glass wool is formed by very thin fibers of glass strands that are almost connected and after cooling, they are bundled together and placed on kraft paper, lead, bitumen, or fibrous net. Due to its non-flammability, glass wool is used to insulate sloping roofs on the sheets of the underlying coverage and in flat roofs under the asphalt or felt covering. Note that this thermal insulation must be kept away from moisture.

mineral wool

Mineral wool insulation is produced by blowing water vapor on fibers made from molten clay-bearing limestone or iron smelting slag. For low-temperature insulation, mineral wool is covered by a sheet of coated bituminous paper. For high temperatures, mineral wool equipped with an aluminum sheet or galvanized mesh is used.

Rock wool

One of the most common thermal insulation in the market is stone wool. This insulation is made from natural siliceous stones. Rock wool is made by passing molten rock fibers through water vapor or hot air. The limit temperature of its use is 850 degrees Celsius. The application of stone wool is like mineral wool. Compared to other insulators, it has less weight and maintains its characteristics after drying. One of the benefits of this insulation is its simple operation, which has made it popular, and rock wool insulation is compatible with all building materials.
Use in fire protection is one of the most important uses of this insulation, in fact, this coating can be used to protect metal structures, elevator shafts, electrical installations, escape corridors, etc. against fire.

Plastics

These insulations include all kinds of plastics, which due to the diversity in the types of available plastics, have caused the diversity of this type of thermal insulation in the market, for example, the names of polystyrene, polyethylene, polyurethane, phenolic foams. , polyvinyl chloride, urea formaldehyde, EPDM foam (ethylene-propylene-diene-monomer), nitrile foam, etc., and are supplied with different characteristics and uses.

Fibreboards

This material is the first thermal insulation of the building, which is made by compressing felt wool and other plant fibers in the form of rigid boards. It simply absorbs moisture and becomes saturated and loses its mechanical strength and stability against heat transfer. This insulation has a weak resistance to fire, that's why it is not a suitable option for use in construction, but due to its low price and stable dimensions, along with the bottom coating, plastic insulation is used as a base for asphalt and felt coating.

Compressed cork board

It is produced by pressing cotton seeds together with its natural gum and is very expensive. This thermal insulation is resistant to moisture, that's why it has many fans in wet places and is used in different uses. The remarkable thing about this insulation is its weak tensile strength, but it has the same high compressive strength.

Sponge glass

This material uses pure glass that expands up to twenty times its volume and turns into solid and spongy insulating plates. It does not absorb water, it is resistant to vermin, and it is stable in terms of insulation and has good pressure resistance, and one of the important and practical features that make it classified as thermal insulation is its fire resistance.

Important points when choosing the right thermal insulation

In order to intelligently choose the required thermal insulation, you need to know about the types of insulation available, their rated thermal performance, ease of use, and of course, their value. You should also consider its environmental characteristics and safety considerations. In the following, we will get to know some of the features of good and suitable thermal insulation.

Resistant to pressure

After installing the thermal insulations, they may be under pressure, so good insulation is an insulation that has the ability to withstand pressure.

Inflammability of insulation

One of the most important things to consider when choosing the required thermal insulation is the non-flammability of the thermal insulation.

Resistant to the growth of fungi

One of the most important and practical points that you should pay attention to in the construction process is maintaining hygiene and cleanliness, which neglecting it provides space for the growth of fungi and microbes, and this is also considered one of the benefits of good insulation. will be

Anti-ultraviolet rays

Another important feature that you should pay attention to in the process of buying insulators is their resistance to ultraviolet rays.

Neutrality against chemical reaction

Note that when installing insulators in buildings or outdoor spaces, they should not react to external factors because this will increase the lifespan of the insulators.

High elasticity against contraction and expansion

Expansion and contraction are some of the things that will affect anybody and are also considered important points in building construction. Good thermal insulation should be able to contract and expand in different environmental conditions.

Advantages of using thermal insulation

Insulation systems are widely used as a solution to reduce the rate of heat transfer through roofs and side walls in buildings. In general, insulation is installed between the framing members and most importantly on the pipes and heating and cooling equipment of the building, such as walls, ceilings, pipes, equipment, etc.
The following are the advantages of using thermal insulation:

• It protects the structure of the building.
• The dew point is moved outside the wall.
• Building ventilation is improved and heat loss is reduced.
• The thermal bridge is reduced, and condensation and heat loss are also minimized.
• It is easy to install and it speeds up the insulation of the building.
• Since the insulation cover is easily visible, it makes it easy to control the quality of thermal insulation

Thermal insulation installation conditions

According to different weather conditions, construction methods, etc., some points should be considered when installing thermal insulation.

• The material of the insulation and its covering should be suitable for working at the temperature of the piping system and the conditions of the place.
• The material of the insulation and its coating must comply with what is stipulated in the national building regulations to protect that area of ​​the building against fire.
• It is not allowed to use fuel materials and materials such as insulation, insulation coating, and other auxiliary materials such as adhesive tape, etc.
• The parts of the pipe that pass through the firewall should not have insulation or insulating coating.
• If the pipe is subject to freezing, the thickness of the insulation shall be in accordance with approved engineering practices, or methods other than insulation shall be used to prevent freezing.
