Thermography is a technique for measuring the infrared radiation emitted by objects with a temperature above absolute zero. Using specific sensors, this technology converts the thermal information into images, known as thermograms, which show the temperature variations on the surface of objects.
Thermal analysis is performed using a thermographic camera, a device that, thanks to its sensors, captures the temperature of objects and represents it visually through a colour map. This method does not require direct contact, which makes it an ideal solution for evaluating systems and structures without interfering with their operation.
In the construction sector, thermal imaging is an essential tool for identifying critical points that affect the energy efficiency of buildings, with the overall aim of reducing heat loss and optimising energy performance. With it, we identify air infiltrations, water filtrations, rising damp, deficiencies in insulation, failures in heating systems, heat losses and thermal bridges in carpentry.
Thermography is an ideal technology for areas of difficult access or high risk. On the other hand, it is a technique capable of identifying temperature variations of tiny fractions of a degree. In a world where sustainability and efficiency are priorities, thermography is a key technology for the future of construction.
