With an infrared thermal imaging camera, the temperature of an object can be measured. Especially the temperature of a building envelope can be visualized with high accuracy. On this basic principle, irregularities can be established. Our thermographers are at least Level 1 certified.
Thermographic survey accordance NEN-EN 13187
With a thermographic survey, irregularities such as insulation defects, thermal bridges and air leaks in the building envelope can be charted efficiently, non-destructively and from a distance (large surfaces). The survey method is based on the measurement of variations in heat transfer by radiation of the infrared part of the spectrum (a range of successive colors). This allows thetemperature distribution on the outside of a facade to be visualized accurately in the heating season. To achieve the desired temperature differences, the building must be heated, and the survey has to be carried out during low outside temperatures. Furthermore, to detect any air leaks, it may be necessary to use under-or overpressure on the building. The thermographic images are compared with the initial estimates of the results (for example, the materials used, construction system, position of heating units, orientation), taking into account the current indoor and outdoor conditions (temperature, pressure, wind).
The analysis of the thermogram should be carried out by a professional, to exclude any false conclusions and hence unnecessary measures.
