Say Goodbye to Empiricism: Infrared Thermal Imaging Cameras Become "Handy Tool" for Supervision and Acceptance

Wall leakage, insulation failure, hollowing and cracks..., these "silent killers" not only threaten the safety of buildings, but are also likely to cause energy waste and high maintenance costs. From commercial blocks, production plants to personal residences, building walls frequently leak, crack, hollow and fall off. It is difficult to accurately find the hidden dangers with the naked eye alone.

Nowadays, infrared thermal imaging cameras are bringing innovative changes to the construction industry! They capture the subtle temperature differences on the surface of objects and convert thermal signals into visual images, making hidden water seepage points, failed insulation layers, wall hollowing, and other hidden dangers nowhere to hide. This technology is becoming a "diagnostic artifact" in the hands of engineers, promoting building inspection from "empirical judgment" to "precise quantification".

01 Application Scenarios

When a supervision company conducts third-party housing construction inspection, it needs to use infrared thermal imaging cameras to detect problems such as water seepage in the basement of a commercial block, facade hollowing, and air tightness of a glass curtain wall to ensure standardized construction and project acceptance.

Basement Water Seepage Detection

The basement area is an important place in a commercial block. Its concrete structure leakage hazards are often hidden, and there are many types of leakage hazards and different complexity of leakage situations. It is difficult to accurately locate them through experience and naked eye observation. Using a single detection method usually cannot accurately detect the leakage point and leakage path.

When conducting basement water seepage detection, inspectors use infrared thermal imaging cameras to shoot key areas such as internal corners, walls, and floors. By observing the surface temperature differences caused by defects such as water leakage and concrete cracks, they can intuitively see the hidden dangers of water seepage and point out the direction for subsequent repairs and improvements.

Facade Hollowing

Hollowing refers to the phenomenon of partial or overall separation between the paint, tiles, stone and other surface decoration materials on the exterior wall of a building and the wall due to loose adhesion.This situation may cause safety hazards to pedestrians and vehicles, as well as lead to problems such as reduced wall waterproofing, leakage, and reduced building insulation performance.

The heat transfer of the hollowed exterior wall surface is blocked and the temperature is different from that of the intact wall. Therefore, inspection personnel can capture this temperature difference with an infrared thermal imaging camera and conduct rapid non-contact, large-area non-destructive troubleshooting to assist in determining the location and size of hollows.

Infrared thermal imaging cameras can not only accurately locate the hollowing, but also, when facing high-rise or distant areas that are difficult to view directly, complete early verification and judgment of hollowing problems by replacing telephoto or medium-telephoto lenses, ans so on, so as to repair them as soon as possible and prevent losses caused by further aggravation of the problem.

Air Tightness Test of Glass Curtain Wall

HVAC systems in large commercial buildings are essential to maintaining air quality, temperature, and overall satisfaction of building tenants. Poor tightness of glass curtain walls will not only lead to a large amount of energy loss, but also easily cause safety hazards. Infrared thermal imaging camera detection allows easy capture of the cold and hot bridge phenomenon caused by poor tightness of glass curtain walls, and locates areas with serious leakage.

During the inspection of the entire commercial block, when the inspectors tested the air tightness of the glass curtain wall, infrared thermal imaging cameras were used to visually view areas with temperature differences, quickly locate poorly sealed areas, and assist in subsequent maintenance and rectification work, thereby improving the energy efficiency and safety of buildings.

02 Product Recommendation

The customer chose an infrared thermal imaging camera for inspection. The infrared resolution of this thermal imaging camera is as high as 640×480, and with the built-in super-resolution algorithm it can reach an infrared resolution of 1280×960, with excellent image quality. It supports panoramic stitching technology, and supports comprehensive temperature analysis of 20 points/lines/areas at the same time. Combined with functions such as intelligent calculation of target zone area, flexible setting of emissivity and laser ranging by zone, as well as multiple professional functions such as temperature calibration-free extended lens function and 0.4s one-button intelligent autofocusing, it can meet various complex usage scenarios in building inspection.

03 Application Advantages

➤ Non-contact detection

Traditional building inspection methods may require destructive testing or local contact, and the results rely on the experience of the surveyor. Thermal imaging cameras can remotely obtain temperature information on the building surface, avoiding damage to the building structure, which not only improves the safety of detection but also reduces losses.
