Thermal imaging, also known as infrared imaging senses differences in temperatures that are otherwise undetectable by the human eye. The thermal imaging camera is the primary tool for thermal imaging. It looks no different from the conventional camcorder, and also operates similarly. It is extensively used in security, navigation, surveillance, firefighting, and medicine. This is also used as a non-destructive testing methodology.
Thermal imaging or thermal video cameras can be used for various facets of building audits and diagnostics. Indoor environments of a building be seriously compromised because of poor insulation, improper sealing of doors and windows, bad quality duct work, plumbing leaks, and other plumbing related issues because of inefficient HVAC systems. More and more construction companies are applying the “whole building” approach to optimize energy efficiencies of buildings. The applications of this technology in energy audits, HVAC & plumbing issues, moisture & restoration, has made it an indispensable tool in the business of building & construction. Infrared video cameras are also used to detect problems that lead to mold growth and indoor air quality.
Most buildings face the problem of presence of moisture due to condensation or leakage. Sometimes, the area of leakage is a lot larger than what is visible. Such water damages can prove hazardous to a structure. Infrared video cameras provide efficient assistance in scanning large areas quickly and thus enabling building professionals to assess the damage and take quick actions for restoration. It helps in tracing the correct area with water intrusion and hidden moisture under the surface. The images provided make it easy for documentation and future insurance claims.
Thermal imaging cameras are the best option when it comes to identifying cracks and gaps in a structure. It helps detect faults in thermal insulation and windows by locating the area through which there are leaks.
This is achieved by detection of areas where heated air in cold regions or cool air-conditioning air I warm regions vanishes. Since warm objects stand out well against cooler backgrounds, thermal imaging also helps in mapping thermal bridges. Thermal bridges are a part of the design of the structure that is less insulated or not insulated at all. These can be holes, cracks, spotlights or other fixtures that go through the insulation layer.
A major benefit of using infrared cameras for testing plumbing issues is that it can be executed with minimal intrusion, floor and ceiling damage and reduced downtime or recurring cost. If time is a constraint to implement a detailed restoration process, techniques such as humidity alarms and automated dew point are also available.
