What is Thermography and How Does it Work?
Thermography, also known as infrared imaging or thermal imaging, is a technique that uses infrared cameras to capture images of heat patterns on the surface of an object or structure. It works by detecting the infrared radiation emitted by objects and converting it into a visible image. This allows inspectors to see temperature variations and identify potential issues that may not be visible otherwise.
Thermography surveys typically involve scanning the entire building, both inside and outside, with an infrared camera. The camera captures images that show temperature variations, which can indicate areas of concern such as moisture intrusion, electrical faults, energy loss, and structural defects. These images are then analyzed by trained professionals who can interpret the data and identify any potential issues.
There are different types of equipment used in thermography surveys, ranging from handheld devices to more advanced systems mounted on drones or helicopters. The choice of equipment depends on the size and complexity of the building being inspected. Regardless of the equipment used, thermography surveys provide valuable insights into the condition of a building and help identify potential problems before they escalate.
