Principle of operation KOFATERM

KOFATERM is a line of water-based paints and pastes that provide thermal reflective coatings capable of saving up to 40% of energy in both hot and cold climates. These products contain densely packed microspheres that reflect over 90% of thermal radiation conducted by electromagnetic waves in the full spectrum of visible light, including thermal (infrared) waves. These waves attempt to penetrate a partition, such as a wall or a roof, scattering inside it before ultimately passing through to the other side. KOFATERM coatings act as a barrier reflecting them away from the surface.

Hot climate

In hot climates, the sun is the main source of heat, and it raises the temperature of the surface of the façade and roof to 80°C (176°F). Prolonged exposure to such high temperatures causes excess heat to penetrate the partition, decreasing insulation efficiency. Some thermal insulation materials may also suffer permanent damage and material degradation thus losing their thermal resistance properties. The thermal energy that penetrates the partition disperses within it, eventually making its way into the interior of the room.

To lower the excessively high interior temperature, air conditioners are used, which consume more energy when the thermal resistance of the partition is lower. Applying KOFATERM pastes to the exterior of the partition will result in lower energy consumption of the air conditioner while maintaining a comfortable temperature indoors. Our solution ensures that the external surface of the partition has a temperature similar to that of the surrounding environment even under prolonged exposure to the sun.

Cold climate

In cold climates, the use of KOFATERM coatings indoors causes the reflection of thermal energy waves off the surface of the internal walls. The desired temperature inside the room is retained, warm air does not penetrate the partition and does not escape to the outside. This significantly reduces the demand for energy required to heat the room. Dependent on previously used thermal insulation materials application of KOFATERM PAINT results in up to 40% energy savings used for heating. The effectiveness of our solution is best illustrated by“before and after” thermal imaging photos of the surfaces treated with KOFATERM coatings.

Temperate climate

The temperate climate is characterized by high temperatures in summer and low temperatures in winter. It is a specific thermodynamic system, in which we want to reflect heat from the outside of the partition (summer) and from its inside (winter). In this exceptional case, KOFATERM coatings should be used both outside and inside the building, thus ensuring savings in both these seasons.

In the summer, the external coating will protect the partition against heating it by the sun, preventing the heat from penetrating the interior of the building. Reducing the temperature in the middle of the room will reduce the energy demand of the air conditioner by up to 40% or eliminate the need for its use altogether. In addition, the coating will protect existing thermal insulation materials against degradation.

In winter, the internal coating will prevent the penetration of electromagnetic wave energy into the partition and the escape of heat to the outside. Inside the building, the convection of warm air masses will improve, the feeling of thermal comfort will improve, and the temperature in the room can increase even up to 7 ᵒC. The effect of increasing the temperature translates into a reduction by about 40% of the energy used for heating the rooms. In addition, the internal coating will prevent the formation of mold, algae and fungus on the wall surface.

The use of KOFATERM coatings inside and outside the building solves all problems related to thermal modernization of buildings in a temperate climate.

What are microspheres?

What are microspheres?

Microspheres are microscopic hollow spheres filled with gas that in conjunction with their shells exhibit superb thermal insulation properties. The near-ideal sphericity of the microspheres resulting from the technology of their production and the high transparency of the coating causes the IR light and heat energy entering such a sphere, as a result of its multiple internal reflections, to return towards the radiation source.

The contents and size of the microspheres in the coating are very carefully selected depending on their intended use to maximize their efficiency. Our coatings and pastes eliminate the phenomenon of local water vapor condensation known as thermal bridges (in corners, intersections, joints, etc.), that commonly occurs in enclosed spaces.

Range of reflection of electromagnetic waves (visible and infrared light)

KOFATERM products are characterized by high adhesion to almost all surfaces, great flexibility, and high abrasion resistance. Thanks to their ability to eliminate thermal bridges and water vapor condensation our products prevent the formation of mold, algae, and fungi on a treated surface.

KOFATERM coatings and pastes are excellent thermal modernization solutions allowing for significant savings with a thin-layer, inexpensive, and easy application process. Our products are characterized by their excellent thixotropic properties resulting in less effort required by the painter during coatings application. Our products find perfect application in any type of construction: residential, industrial, hospitals, public utility buildings, refineries, oil storage tanks, animal husbandries, transportation containers requiring desired temperature levels (hot or cold) and virtually anywhere we desire to isolate and direct the penetration of thermal energy waves.
