What is the thermal conductivity and its significance?

Thermal conductivity - is a quantitative property of substances flowing heat which is determined by the coefficient. This figure is the sum of the amount of heat which passes through a homogeneous material having a unit length, area and time at a single difference in temperatures. SI system converts this value into the heat conduction coefficient is a alphabetical designation is as follows - W / (m * K). The thermal energy is propagated through the material by rapidly moving heated particles which, when a collision with a slow and cold particles transmit their heat stake. The heated particles are better protected from the cold, the better preserved accumulated heat in the material.

Important! To achieve better thermal insulation is necessary to assemble a variety of materials. Compatibility between surfaces is specified in the instructions from the manufacturer.

Explained figures in the table of thermal conductivity and insulation materials: their classification

Depending on the design features of the design that needs to be warm, kind of insulation chosen. For example, if the wall is built of red brick in two rows, then to complete the isolation of suitable foam is 5 cm thick.

With a wide range of density foam sheets they can produce excellent thermal insulation of walls of OSB and plaster from the top, which will also increase the efficiency of the insulation.

You can see the level of thermal conductivity heater, Tabular representation of the photo below.

classification of thermal insulation

By heat transfer method for heat-insulating materials are divided into two types:

Insulation that absorbs any impact of cold, heat, chemical exposure etc .;
Insulation, able to reflect all kinds of impact on it;

From the value of the thermal conductivity of the material from which it is made insulation classes are distinguished by:

A class. Such insulation has the lowest thermal conductivity is 0.06 W maximum value (m * C);
B class. SI has an average parameter and reaches 0,115 W (m * C);
In class. Endowed with high thermal conductivity and indicator shows at 0,175 W (m * C);

Note! Not all heaters are resistant to high temperatures. For example, ecowool, straw particleboard, fiberboard and peat require reliable protection against external conditions.

Main types of material heat transfer coefficients. Table + examples

calculation of required heaterWhen it comes to the external walls of the house comes from the regional location of the building. In order to explain clearly how it happens in the table below, These figures will concern the Krasnoyarsk Territory.

Type of material	*Heat transfer in W / (m ° C)**	Wall thickness mm	Illustration
3D panel	5500
Hardwood trees humidity 15%	0,15	1230
Concrete based on expanded clay	0,2	1630
Penoblok a density of 1 thousand. kg / m³	0,3	2450
Coniferous trees along the fibers	0,35	2860
oak paneling	0,41	3350
Brick wall to a solution of cement and sand	0,87	7110
reinforced concrete overlap	1,7	13890

Each building has a different resistance to heat transfer materials. The following table which is an extract from SNiP, vividly demonstrates.

Examples of thermal insulation depending on the thermal conductivity

In modern construction standard steel wall, consisting of two or even three layers of material. One layer consists of heaterWhich is selected after certain calculations. Additionally, you need to find out where the dew point.

to organize exact calculation you need to use multiple complex SNiP, guests, benefits and joint venture:

SNP 23-02-2003 (SP 50.13330.2012). "Thermal protection of buildings". Revision of 2012;
SNP 23-01-99 (SP 131.13330.2012). "Building Climatology". Revision of 2012;
SP 23-101-2004. "Design Thermal protection of buildings";
Allowance. EG Malyavina "Heat loss of the building. A Reference Guide ";
GOST 30494-96 (GOST 30494-2011 replaced by a 2011). "Residential and public buildings. parameters of the microclimate in the premises ";

Performing calculations on these documents, determine the thermal characteristics of the building material, walling, heat transmission resistance and the degree of coincidence with the regulatory documents. calculation of parameters based on the building material of thermal conductivity of the table shown in the photo below.

Advice and recommendations on the choice of materials

Do not be lazy to spend time studying the technical literature on the thermal conductivity of the materials properties. This step will minimize the financial and heat loss.
Do not ignore the particular climate in your area. Guest information on this subject can easily find on the Internet.
climate feature
Before proceeding to the installation of insulation, ensure that the surface of the wall or ceiling is not moisture. Otherwise, after the time between mold surfaces is formed.
Mold on walls
If you plan to mount nevlagostoyky material on the outside of the wall, take care of careful processing waterproofing glue.
Tightening the foam waterproofing
It is not necessary to produce internal insulation surfaces of synthetic materials. This has a negative impact on your health.
