Thermal Insulator

Thermal insulation is used to reduce energy loss in the cold and hot seasons of the year in heating and cooling facilities of buildings. In the following, the information, application, how to check, and the best price of all types of building thermal insulation are provided for wholesale purchase.

A Guide to Select Thermal Insulators for Buildings

In general, in heating and cooling facilities of buildings, in order to reduce heat loss and energy consumption, to prevent moisture infiltration and even sound transmission on building surfaces, pipes, tanks, and channels, various types of insulation are used. In addition to the heating and cooling facilities of buildings, the use of insulators is widely used in various industries such as petrochemical, oil, chemical, automotive, shipbuilding, aircraft, power plant, and pharmaceutical industries.

The evolution of insulations has taken a long path, including the transition period from mineral insulations such as glass wool and stone wool. Now, it has led to a new generation of insulations known as polymer insulations. Polymer insulation has many advantages, including ease of installation, flexibility, and lightweight.


Types of thermal insulators

In choosing the type of thermal insulation in the category of building and engine room heating equipment, one should pay attention to the ambient temperature as well as environmental conditions and even appropriate safety in different conditions. One point that is very important in choosing thermal insulation is its economy; that is, with a minimum thickness of insulation, it is possible to avoid wasting energy.

Mineral fiber thermal insulation

Mineral fiber insulation is made by crushing the granules of slow-melting fire-fighting stone. In addition to being non-flammable, these insulators are also heat and sound insulators, which are used in the form of flexible or uncoated light mats to insulate sloping roofs on the underlying cover plates. Another notable feature of mineral fiber insulation is to prevent the growth of fungus and mold and to be odorless and moisture-repellent.

Rock wool thermal insulation

One of the most common thermal insulations available in the market is stone wool insulation, which is lighter than other insulations and maintains its properties after drying. One of the advantages of these insulations is their simple operation, which has made them popular, and rock wool insulation is compatible with all building materials.
Using in fireproof situations of the building is one of the most important applications of this insulation. In fact, this coating can be used to protect metal structures, elevator shafts, electrical installations, escape corridors, etc., against fire.

Glass wool thermal insulation

Glass wool insulation is formed by very thin fibers of glass strands that are almost connected and are bundled together after cooling and placed on kraft paper, lead, bitumen, or fiber net. Due to its non-flammability, glass wool is used to insulate sloping roofs on the sheets of the underlying coating and in flat roofs under the asphalt or felt coating. Note that this thermal insulation must be completely away from moisture.

Plastics thermal insulation

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, with the names of polystyrene, polyethylene, polyurethane, poly Vinyl chloride, and EPDM (ethylene-propylene-diene-monomer) foam insulations are available with different characteristics and uses.

Sponge glass thermal insulation

Sponge glass, using pure glass, expands up to twenty times its volume and turns into solid and spongy insulating plates. This insulation has good pressure resistance, and one of the important and practical features that has made it classified as thermal insulation is its fire resistance.

Perlite thermal insulation

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 also 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. Also, due to the connection of its holes together, it sucks water like a sponge, and its resistance decreases as water penetrates it.

Fiberboard thermal insulation

This material is made by compressing felt wool and other plant fibers in the form of rigid boards that easily absorb moisture, become saturated, and lose their mechanical strength and stability against heat transfer. This insulation also has a weak resistance to fire, which is why it is not a suitable option for use in building construction, but due to its low price and stable dimensions, along with the bottom coating of plastic insulation as a base for asphalt and felt coating in some Projects are used.

Compressed corkboard thermal insulation

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

Application of building thermal insulators

In most cases, thermal insulation is used in different industries, and each one has different applications. Building thermal insulation reduces a large amount of energy consumption by maintaining the proper temperature in buildings (cooling and heating). In this case, the use of building thermal insulation plays an important role in this direction. Among the important features of building thermal insulation, the following can be mentioned:

  • The need for a long life
  • It has the right density
  • High resistance to ultraviolet rays
  • No deformation against heat and high heat
  • Neutrality of insulators against chemicals
  • Keeping the heat transfer coefficient constant and improving the thermal performance.
  • It is necessary and mandatory to be resistant to germs and fungi
  • High thermal insulation resistance against fire and ensuring the safety of residents

How to choose and order thermal insulators

When choosing and ordering insulators, the following should be taken into account:

  • Temperature difference between two insulating surfaces
  • Heat transfer coefficient of insulation
  • Insulation material and its coating

Choosing the type of thermal insulation depends on the ambient temperature, safety, environmental conditions, and price. The thickness of thermal insulation should be chosen in such a way that it is economical from the point of view of the economy, that is, to prevent energy wastage with the minimum thickness of insulation. The main thermal insulation materials are:

Light concrete (aerated concrete and floor concrete), light grains, paper and aluminum, mountain cotton, pressed cork, fiberboards, mineral fibers, stone wool, glass wool, sponge glass, pumice stone, perlite, gypsum boards Light with simple aluminum coating, plastic materials, hollow stems, wood wool and different types of polymer insulation and foams.

Important points in the implementation of Thermal insulators

In the implementation of insulation, the following points should be taken into account:

  1. The material of the insulation and its covering must be in accordance with what is stipulated in the national building regulations of Iran to protect that area of the building against fire.
  2. The use of fuel materials and materials as insulation, insulation coating, and other auxiliary materials is not allowed.
  3. For pipes that are subject to freezing, the thickness of the insulation should be chosen by a careful expert, or other methods than insulation should be used.
  4. The thickness of the insulation is determined based on engineering calculations, and note that greater insulation thickness does not always reduce heat loss.
