Thermal Insulation Materials

İçerik 05.02.2015
Material selection is important for the application of the thermal insulation. In thermally insulated surfaces, for the water vapor resulting from the vital activities to be transferred from internal to external environment in the vapor phase, ventilation capabilities of all thermal insulation system products, especially thermal insulation plates should be at the maximum level. Moreover, in order to prevent the fractures which may form on surfaces within years, it is an essential property for a thermal insulation system that materials used in the thermal insulation system, especially the thermal insulation plates should be flexible.

Thermal insulation materials are special materials which have high thermal resistivity and which are used for reducing heat losses and gains. In terms of European Standards materials, thermal conductivity coefficients of which are below 0.065 W/m.K, are described as thermal insulation materials.

Thermal insulation materials are special light materials with high resistance against heat transmission that are used to decrease heat loss and increase savings. Commonly used thermal insulation materials in our country are:

- EPS, XPS, glass fiber, stone wool, polyurethane and wood for walls, headlinings and roofs;
- thermal, sun, thermal+sun control coated insulation glass units and insulated woodworks for windows;
- glass fiber, stone wool, polyethylene foam, elastomeric rubber foam, polyolephine foam for air ducts, pipes and valves.

The main purpose of thermal insulation products is to increase the thermal conductivity resistance of the structural elements.

Therefore, thermal conductivity coefficient determines the insulation characteristics of these products. The lower the thermal conductivity coefficient is, the higher the insulation performance of the product is. For this reason, thermal conductivity coefficient of the insulation products is required to be low. In addition to this, according to the application, insulation materials' sound damping values, performances regarding fire, water absorption values, freeze-thaw resistances, compressive strengths for loaded applications play an important role in material selection. Further, ease of use and being economical are the other properties that a thermal insulation product should have. Thermal insulation products are listed below with their standards as to their application fields.

Thermal conductivity coefficient l(W/mk): It is the quantity of heat transmitted by the material depending on physical and chemical structure of it. Examples: Iron l=58 / Concrete: l=2.1 / Brick wall l= 0.3 / Wood l=0.2 / Standard EPS (16 kg/m³) l= 0.040 / Capatect Dalmaçyalı Thermal Insulation Plate l= 0.033. The less the value I is, the less that material transmits heat.

Thermal conductivity coefficient (λ) is not the only criterion for comparing thermal insulation values of materials. Performance of a thermal insulation material is directly proportionate to how thickly it is applied. The thermal resistance (R) value is the criteria which gives us the most obvious information about the comparison of performance of insulation material used and other materials. Thermal Insulation is defined as the resistance of a material which is performed against heat transmission between two medias. The higher this value is, the higher the resistance performance of the materials against heat transmission have.

R=d/λ d is the thickness of the material in meters.
λ; is the thermal conductivity coefficient of the material in W/mK.
R; is the thermal resistance of the material in m²K/W.

You can form an opinion about the insulation performance of products by evaluating all the thermal insulation products offered to you with these properties.

Heat transmission coefficient U (W/m2K) : It is the resistance of a construction material constituted by laying different materials one after another performed against heat transmission. U depends on the thermal conductivity coefficient ( I ) of materials and thickness in the direction of heat transmission. The less the value of U is, the less the heat transmission becomes.

Moreover, TSE standards of the Thermal Insulation Products give you information on thermal insulation classes and properties of the relevant products.

Capatect Thermal Insulation Plates are produced according to TS EN 13163 "EPS Thermal Insulation Plates Standard" and CE criteria. Contrary to common opinion, the most widely used application in our country is thermal insulation systems in which EPS, XPS and Stonewool plates are used. The most preferred product is the thermal insulation system applied by EPS plates with a rate of 60%.
