Find out about the 6 main properties of GoTherm thermal insulation paints and find out if they will help you solve your problems.
Heat is transferred by convection, thermal conductivity and radiation. GoTherm works for two of them:
- Radiation– this parameter is ignored in the case of traditional insulations such as wool or polystyrene. On the other hand, paint reflects over 90% of radiation.
- Thermal conductivity – lambda, which is a parameter used by the construction market, is the thermal conductivity coefficient. For polystyrene, it is a value of about 0.030 to 0.045 W / (m * K), and in the case of wool, the coefficient ranges from 0.032 to 0.038 W / (m * K). According to the study carried out by the Silesian University of Technology, which consisted of measurements using the comparative method, lambda, depending on the test temperature, ranges from 0.00153 to 0.0099 W / (m * K).
Based on the performed tests and own measurements as well as feedback from the investments made, we can assume that the 1mm thick GoTherm paint layer is equivalent to approximately 2.0-2.5 cm of polystyrene.
How does condensation occur?
Water condensation (so-called water vapor condensation) on surfaces depends primarily on the temperatureand humidity of the air. Water vapor in contact with a cold partition with a temperature below the so-called The “dew point” condenses and causes moisture to accumulate.
The precipitating condensate often leads to significant heat losses as well as degradation of the surface finish of the partitions.
Condensation of water
The paint shifts the “dew point” and blocksthe formation of condensate on these surfaces. Thanks to its thermal insulation properties, it blocks the condensation of water vapor, insulates and protects the substrate against unfavorable conditions.
The pictures opposite show the temperature difference on the surface of the chilled water system. After applying only 1.2 mm of the paint, condensation was stopped.
The research carried out by the Silesian University of Technology confirms that even a few minutes’ touching of surfaces transporting the medium with a temperature above 80°Cand protected with thermal insulation paint does not cause any injuries.
The photo below shows the valve on the installation transporting the medium at a temperature of about 200 degrees C, the temperature of the valve surface is 160°C, as you can see after applying the 3mm thick coating, you could freely touch the insulated parts.
Tests carried out by the Institute for Engineering of Polymer Materials and Dyes in Gliwice confirmed that the total solar radiation reflection coefficient TSR for paints exceeds 90%. The phenomenon of “urban heat islands”, overheated attics and buildings heated to very high temperatures include effects caused by solar radiation. Reflective paint, which acts as a shield and reflects the radiation, can reduce these adverse effects.
The paint significantly improves the thermal comfort inside halls, warehouses, container rooms or metal garages, and also reduces the cost of energy used by air conditioners.
The use of coatings significantly reduces the costs of energy consumption, needed, for example, to cool the contents of tanks outside and exposed to direct sunlight.
Microbiological tests commissioned by us, performed in the Microbiology Laboratory, confirmed the antimicrobial effect of coatings on the most common bacteria causing the spread of infections, such as Staphylococcus aureus.
The results of the research leave no illusions and clearly confirm that in the case of Candida albicans, the fungicidal effectiveness is 99.8%.
The conditions that favor mold growth most often occur at the site of thermal bridges. This is where the moisture builds up and maintains the temperature at which mycelium builds up and the mold spores rapidly multiply on the wall.
Thanks to its anti-mold properties, GoTherm effectively prevents the growth of mold and protects the surface against its re-bloom.
