The use of infrared thermography in the construction field allows solving problems such as:
- Water or water infiltrationhumidity excessive;
- Air infiltration or exfiltration;
- Inadequate insulation;
- Thermal bridges.
Moisture problems
Moisture and thermal discomfort are among the most common problems reported by building owners. These issues are related to deficiencies in the insulation and airtightness of the building envelope.
Here are the three main causes of humidity in a building:
- Water infiltration;
- Condensation;
- Rising damp (migration of moisture into walls in contact with damp ground)
Thermal discomfort and insulation
It is important to protect the building envelope with insulation . The role of insulation is to slow down air circulation through the envelope. Therefore, airtightness is essential to ensure good energy efficiency and to regulate mechanical and natural ventilation.
The building envelope
Infrared thermography is a technique that allows for the analysis of energy losses and it is non-destructive.
The test carried out by a specialist makes it possible to diagnose the condition of the building envelope and to determine the locations of heat loss in the envelope.
Several cases of hidden defects in buildings have been processed using technical infrared thermography.
