What kind of insulation is: advantages and disadvantages

Good thermal insulation will not be superfluous at any temperature. If you perform it efficiently and choose the right insulation, there will be more warmth in the house in the cold season, and coolness in the summer heat. Knowing what kind of insulation is , you can easily choose the best option for interior or exterior decoration.

What kind of insulation is: advantages and disadvantages
Variety of types of heat insulators

What types of insulation are

There are several criteria for dividing heat insulators into specific groups. The classification is based on the purpose, form and composition of materials.

Varieties of insulation in the form

When choosing a material according to this criterion, it is necessary to consider what surface it will be mounted on. For external walls, plate or block heat insulators are more suitable. It is better to insulate the inside of the house with fibrous or roll materials.

Table 1. Types of heat-insulating materials in shape:

To choose the right insulation, you need to be well versed in its varieties.

Then it will last longer and will perform its functions to the fullest.

Types of insulation by composition

This classification is based on what raw materials the product is made from. Heaters on a natural basis are more suitable for interior decoration, and artificial materials are used for external thermal insulation or for rooms with high humidity.

Table 2. Classification by composition:

Organic Inorganic
Arbolit Polyfoam
Particleboard Foamed polyethylene
Fibrolite Penoplex
Ecowool Sotoplast insulation
Mineral wool Expanded polystyrene

Each type of material has its own set of characteristics.

It is used to determine how suitable it is for insulating a particular object.

Types of insulation according to the principle of operation

There are two types of thermal insulation - reflective and preventing . The first type reduces heat consumption by lowering the level of infrared light.

Reflective insulation, instead of retaining heat, prevents infrared radiation from freely passing through the walls of the house. They do not transmit heat, but reflect.

Most often, aluminum foil is used for these purposes. The surface of this material can reflect 90-97% of the heat that hits it.

The aluminum foil is laid in several layers. The last layer is covered with polyethylene. Such a heater does not take up much space, but at the same time maintains a comfortable microclimate in the house for a long time and at the same time serves as a vapor barrier.

Reflective type of insulation - aluminum foil

The second type involves the use of insulation with low thermal conductivity. For its manufacture, different groups of materials are used - organic and inorganic. Such heat insulators act according to a certain mechanism.Their role is to slow down the process of heat passage - so that it does not go outside for as long as possible.

What are the types of insulation for walls?

To choose a heat insulator for walls, you first need to understand its types and their technical characteristics.

"The main property of the insulation is the degree of thermal conductivity. This is an indicator of the amount of heat that this material is able to transmit."

Materials of organic origin are used for interior decoration. They are made using natural raw materials - waste from the woodworking industry or agricultural products. Additional components are plastic and cement.

Each species has its own characteristics.


For its manufacture, crushed sawdust, wood chips and reed stalks are used. Cement with calcium chloride and alumina is used as a binding component.

What kind of insulation is: advantages and disadvantages
Insulation of the facade

"The correct choice of insulation and its high-quality installation ensures uniform heating in room due to the free circulation of heated air.

The outer layer of the heat insulator retains heat longer, which allows the walls to be dry. This protects them from premature destruction. "

External thermal insulation has other advantages as well. Due to it, it is provided:

  • protection of the facade from aggressive environmental influences;
  • additional noise isolation;
  • unobstructed "breathing" of the walls.

Different types of materials are used as insulation.

"Warm" plaster

As a basis for the preparation of this mixture, cement mortar is used, only instead of sand, the following components are added to it:

  • crushed pumice stone;
  • perlite sand;
  • expanded clay crumbs;
  • expanded polystyrene granules.

"The optimal period for facade work is from the end of spring and until the beginning of autumn, when the average air temperature is + 5-25 degrees. It is undesirable to carry out thermal insulation of facades in extreme cold or heat - this reduces its quality and service life. "

Heaters for a wooden house

Wood is considered a special type of material.

Walls made of it should be well ventilated and less in contact with moisture. Therefore, not all types of heat insulators are suitable for wooden buildings. Mineral wool or penoizol is most suitable for this purpose.

"Styrofoam cannot be used to insulate a wooden house. It will prevent the tree from breathing normally.

As a result, condensation forms on the walls, which will lead to the appearance of fungus and mold, and the wood will start to rot."

What are the dimensions of the insulation

What kind of insulation is: advantages and disadvantages
The dimensions of the insulation is an important criterion

What is the kind of insulation

The main criterion when choosing the dimensions of a heat insulator is its thickness.

Length and width do not play a big role. They are taken into account only when calculating the required amount of materials. The dimensions of the insulation depend on its belonging to a particular type.

Table 3.Insulation dimensions:

Name Thickness Length Width
Polyfoam 20-100 mm 500-2000 mm 1000 mm
Penoplex 20-100 mm 1200-2400 mm 600 mm
Mineral wool 46-214 mm 1176 mm 566-614 mm
Isolon 3.

5-20 mm

From 10 m 600-1200 mm
Arbolit 250 mm 500 mm 200-400 mm
Chipboard 10-22 mm 1830-2800 mm 20170-2620 mm
Fiberboard 30-150 mm 2400-3000 mm 600-1200 mm

When buying materials, you need to pay attention to the area of ​​the roll or plate. Usually it is indicated on the packaging. To calculate how much insulation you need, you need to do the following:

  1. Calculate the perimeter of the building - add the length and width. Multiply this amount by 2.
  2. Measure the height and multiply this value by the perimeter of the house.

  3. Divide the resulting value by the area of ​​one roll or plate.
  4. Multiply this number by 0.15.

"Roll insulation is recommended to be laid with a small margin. Also, any material is subject to shrinkage, therefore 10-15% is always added to the calculations".
