Thermal Insulation

All walls, columns, beams and curtain wall surfaces on the exterior are insulated. And since there will be no remaining heat bridge, heat loss will be minimized.

* Building’s exterior shells are protected from negative atmospheric conditions. They are not subject to extreme heating or cooling, heavy rain or frost.

* And since the building’s elements will be unaffected by sudden changes in the temperature, there will be no cracks or bubbling resulting from expansion or contraction. Thus, maintenance costs can be minimized and the lifespan of the building increases.

* Moreover, reinforced concrete building elements (such as columns, beams and curtain walls) preserve their original resistance against earthquakes for many years.

Moreover, Exelans Energy thermal insulation system is a thermal insulation system with elements working in harmony, from adhesive mortar to topcoat and paint. For the first time in Turkey, this product received the certificate for compliance with TS EN 134999 "Standard for Expanded Polystyrene Based External Composite thermal insulation systems Used in Buildings.”

Reinforced Concrete λ = 2.10 W/mK
Brick λ =  0.45 W/mK
Wood λ = 0.20 W/mK
Aerated Concrete λ = 0.14 W/mK
EPS(16kg/m³) λ = 0.040 W/mK 
Rock wool λ = 0.040 W/mK
Exelans Energy Neopor / Carbon Innova λ = 0,032 W/mK 
Exelans Enerji XPS λ = 0,030 W/mK
Exelans Energy NeoporTURBO λ = 0,029W/mK 

As value λ gets smaller, thermal conductivity decreases.

Materials whose thermal conductivity coefficient is less than λ=0.065 W/mK are defined as thermal insulation materials. Others are defined as construction materials. 

The thermal resistance (R) value is the criterion that gives us the most accurate information about the performance of an insulation material and its comparison with other materials.

Thermal resistance is defined as the resistance of a material against the heat transfer between two mediums. As this value gets higher, the materials resist heat transfer more. The product with a higher R value has a higher insulation value.
R=d/ λ

d is the thickness of the material in meters.
λ is the thermal conductivity coefficient of the material in terms of W/mK.
R is the thermal resistance of the material in terms of m²K/W.
You can get an idea about the insulation performance of various products on offer by comparing their thermal insulation based on this property.

This is the heat transmission resistance of the construction element composed of different elements used one after the other on walls to be insulated.

U depends on the thermal conductivity coefficient (λ) and thickness on the heat transmission side. As U gets smaller, heat loss reduces.

U=1/R U: Heat Transmission Coefficient

Exelans Energy EPS (white), Neopor (gray) and Carbon Innova (gray) panels produced between the densities of 16-30 kg/m³ are offered as 50 x 100 cm with thickness options from 2 to 10 centimeters.

Exelans Energy XPS Panels produced in densities of 22 kg/m³, 26 kg/m³ are offered as 60 x 130 cm with thickness options of 3 to 8 centimeters.  

Exelans Energy XPS Panels produced in densities of 28-30 kg/m³, 30-32 kg/m³ are offered as 60 x 130 cm with thickness options of 3 to 8 cm centimeters.
And Exelans Energy Rock wool Panel is offered as 50 x 100 cm with thickness options of 3 to 8 centimeters.

Since Exelans Energy Panels are derived from petroleum, it is not possible for them to disappear or melt away by themselves. Thermal insulation systems have been and are still successfully applied to millions of square meters in Europe and many countries around the world for the past 50 years.  

As long as your building stands still, Exelans Energy thermal insulation system will do the job.

Among Exelans Energy thermal insulation panels, EPS and carbon EPS are produced at a minimum density of 16-kg/m3, which is a highly recommended European Standards and the most suitable solution in terms of engineering. Based on this density, the panels gain the ideal flexibility. For exterior applications, the flexible insulation panels are preferred rather than rigid panels on upper floors.

The water vapor produced inside a structure at a specific amount every day is discharged through the exterior surface by diffusion. If the water vapor permeability of the panels used for insulation is low, this naturally discharged water vapor goes elsewhere and causes the formation of moisture and mold on interior walls, increasing the risk of sweating and condensation. Buildings insulated with Exelans Energy EPS, carbon EPS and rock wool breathe much more comfortably, which facilitates the discharge of water vapor from the building.

Exelans Energy Polystyrene Panels have a water absorption capacity way below limit values, such as maximum 3% in EPS derivatives and 0.5% in XPS, when they are fully submerged in water and kept in water for 28 days, according to TSE standards When the fact that the water on a building’s surface flows down because of gravity (since such high exposure to water is not possible on the building surface), Exelans Energy Panels will not absorb any water in real life situations.

Exelans Energy EPS, Neopor, Carbon Innova and XPS thermal insulation panels ability to resist fire is Class E, according to TS EN 13501-1 standard (according to the old regulation DIN 4102, Class B1 Fire Resistance). The heat resistance of Exelans Energy Rock Wall thermal insulation panels is Class A, according to the same standard.

Exelans Energy polystyrene panels are rested according to standards after production. There is no change in their dimensions or angles during or after application.

The quality of the glass fiber mesh used in thermal insulation is key to the long-term resistance of the entire thermal insulation system. Thus, meshes used in thermal insulation should be produced from alkali-resistant glass fiber and weigh 160 g/m2. All meshes found in Exelans Energy thermal insulation system are produced with special coatings that are resistant to alkalis.

Exelans Energy Decorative Coats are cement based and are in powder form in the packaging. They are applied after mixing with a specific amount of water. Exelans Energy Decorative Coat must be applied with Polisan External Paints in two coats.

Exelans or A1 Rough paints have hydron technology and silicon additives. They are ready to use and the leftovers can be preserved and used later. In addition to 24 vivid stock color options, they can also be produced in the color of your choice in the minimum order amount.

In cases that a 51% majority is constituted in the complex or apartment, thermal insulation can be applied by authorizing the apartment and/or complex manager.

The 2008 Regulation TS 825 on Building Thermal Insulation Rules and Building Energy Performance (BEP) need to be followed while applying thermal insulation.

Existing building: In the entire building or independent sections of the building, the standard should be followed in terms of ensuring given or recommended thermal conductivity coefficients or lower values.

New constructions: Covers the rules for the calculation of the heating energy need of the building that will be constructed by the engineering company that prepared the project, the highest heat loss value that will be allowed and the method of presenting the information about these calculations.

In TS 825, cities and some districts are classified under four different degree-day regions according to the climate conditions of their geographical location. And for each degree-day region, acceptance criteria such as monthly temperature averages and magnitudes of solar energy radiation used in calculations are determined. Below, degree-day regions and their insulation thicknesses according to TS 825 are given.

U values recommended by TS 825:
Region W/m²K Panel Thickness
Region 1 0,032 4 cm
Region 2 0,032 5 cm
Region 3 0,032 6 cm
Region 4 0,032 8 cm


Exelans Energy thermal insulation panels are firmly affixed to the exterior surface using Exelans Energy Thermal Insulation Adhesive and after a minimum of 24 hours they are fixed with Exelans Energy Dowels. The surfaces of the panels are plastered in 4mm thick Exelans Energy Thermal Insulation Plaster with a layer of Exelans Energy Glass Fiber Mesh in between. On top of this plaster coat is applied Exelans Energy Mineral Coat and then two coats of one of the Polisan paint alternatives. The application is then complete.

The Exelans Energy thermal insulation system is composed of four different system packages (EPS, XPS, rock wool and carbon EPS). The cost varies based on which package and which products you will use within the system. The labor costs differ based on the region and the size of the job.

For a net price offer for your apartment, your building must be inspected by Polisan Boya’s recommended contractors and for you to select the suitable insulation thickness and topcoat decorative material.

Experts must examine your building and thermal insulation applications that will solve your problem must be made by insulation companies experienced in their field. The quality of the application directly affects the performance and lifespan of the thermal insulation system. Thus, when you contact Polisan Boya, we can arrange you to meet with a contractor closest to you.

On walls, choose an exterior thermal insulation application. In this way, both the thermal storage capacity of the facade material is used and the risk of condensation is eliminated within the wall cross section, as well as the interior surface of the wall.

Moreover, heat bridges will not occur since the entire exterior surface is protected with insulation materials. However, for areas that require heating in the short term, internal insulation systems should be chosen.

If the existing frame has the adequate properties, it is possible to use heat control or heat and sun control coated insulation windows with superior insulation properties besides wider intervals (12mm or 16mm) by only making small adjustments on the glass mounting holes. And it is possible to make single-glazed wood frames suitable for insulation by adding a lath.

Exelans Energy Thermal Insulation Systems can be applied on concrete boards. Exelans Energy thermal insulation systems can be applied to concrete boards with Acrylic Thermal Installation Adhesive and F1 Polyurethane Adhesive. It is possible to make application on wood with Exelans Energy OSB Dowel.

Regardless of the surface properties, we recommend thermal insulation is always applied to roughly plastered surface on new buildings. Applications to such surfaces will provide advantages both in terms of labor and materials consumption.

If the building surface to be insulated is not roughly plastered and it is made of hollow brick or cinder block, for example, more thermal insulation adhesive will be used.

Similarly, if the building surface is made of aerated concrete without rough plaster, the absorbent surface of the aerated concrete should be humidified based on weather conditions. Moreover, Exelans Energy Aerated Concrete Dowel must be used.

If the surfaces to be insulated are made of concrete board, OSB or wood, Acrylic Thermal Insulation Adhesive and Exelans Energy OSB Dowel should be used.

During application, 40% of the panel surface should contact the adhesive. Ensure that there is no space without adhesive on the corners and there is no adhesive at the joints of the insulation panels.

General adhesive bonding methods are used for Exelans Energy rock wool thermal insulation panels. The only difference is to use a dowel washer in order to improve fastening.

Insulation should definitely be applied to the entire building. Insulation on a single side will cause formation of heat bridges and thus heat loss on the other faces without insulation will continue. All building components (roof, wall, floor, projection, window and frame) should be insulated.

First of all, the factors behind the influx of water should be examined and precautions should be taken against them. If water influx is seen only on rainy days, then the cracks and holes in your building should be repaired by using water insulation materials.

If there is no visibly deep crack or hole in your wall and there are plaster bubbles, dark spots, mold and similar formations on the interior surfaces, then there is a thermal insulation problem.

Thermal insulation can only be achieved with thermal insulation materials with low thermal conductivity coefficient and thickness in line with the standards. With materials applied in low thicknesses, such as thick paint or plaster, high performance cannot be obtained. As the thickness of a thermal insulation material increases, its insulation performance increases.

Materials such as aerated concrete, all bricks and cinder blocks are each construction materials, not thermal insulation materials, according to Regulation TS825 even though their thermal insulation values are low. Regardless of the materials used in the building, all surfaces including columns and beams, roofs and floors, should be insulated with thermal insulation materials, and special coated insulation glass units and insulated frames should be used on windows.

Sidings do not provide thermal insulation. Generally these materials only change the outer appearance of the exterior and only sometimes resist impacts at heights that people can reach. The energy efficiency of the buildings is obtained through the use of thermal insulation materials behind these materials.

Thermal insulation in installations can be precautions required in order to prevent heat loss at hot lines and heat gain at cold lines. With such installations, corrosion of pipes due to condensation is also prevented besides heat loss or gain.

Increasing the thickness of glass will make no contribution to thermal insulation and thus it is not possible to achieve thermal insulation with this method. The first solution for thermal insulation in glass is double–glazing, which traps dry air between the two panes and decreases heat loss by 50% compared with single glass.

Insulation precautions on windows can be grouped into two based on different purposes. Solutions for heat insulation: Use heat-control coated insulation glass in buildings that are only heated.

In winter, there is a significant heat flow from the interior to the exterior. Thus, in heated buildings, heat control coated windows limit this heat flow and energy is used more efficiently.

Solutions for heat insulation and sun control: Use heat- and sun-control coated insulation glass on building that are both heated and cooled.

Sun control limits unwanted solar heat during summer months. Thus, in buildings that are both heated and cooled, use heat- and sun-control coated insulation glass to ensure the desired comfort level, decrease the amount of energy spent cooling with air conditioners and limit heat gains through the windows.

Thermal insulation offers savings on both the energy and fuel you consume to warm your home during winter and cool it during summer to create a comfortable living space. Since cooling requires more energy than warming, thermal insulation is also necessary in hot regions.

Our company does not recommend such applications since the capacity of interior insulations' to fully prevent heat bridges (floors and cross sections of walls facing outside) brings numerous disadvantages such as condensation and sweating. You can get assistance from our technical personnel for spaces that definitely require such applications.

Our company does not recommend sandwich walls due their inability to prevent heat bridges.

Exelans Energy polystyrene thermal insulation panels provide minimal sound insulation. However, as known, mineral products such as rock wool and fiberglass panels offer definite sound insulation.
