Introduction to Building Thermography: Detecting Non-Visible Defects
Building thermography is a powerful tool used to identify non-visible defects in structures. By utilising infrared technology, thermographers can detect anomalies that are not visible to the naked eye.
Building thermography involves the use of infrared cameras to capture thermal images of buildings and structures. These cameras detect the infrared radiation emitted by object surfaces and convert it into a visual representation of temperature values. By analysing these images, the temperature variations and heat gradients, thermographers can identify areas of concern that may indicate the presence of defects or anomalies.
Thermography is based on the principle that all objects emit infrared radiation, which is directly related to their temperature. By measuring and visualising this radiation, thermographers can identify temperature differences that may indicate hidden issues within a building.
Building thermography relies on the use of infrared cameras, also known as thermal imaging cameras. These cameras are equipped with sensors that can detect and measure the infrared radiation emitted by objects. The captured data is then processed and converted into a thermal image, where different colors represent different temperatures.
During a thermographic inspection, a thermographer scans the building or structure using the infrared camera. The camera captures the thermal patterns and displays them in real-time on a screen. The qualified thermographer analyses these patterns to identify temperature variations that may indicate the presence of defects not seen by the eye.
