ABSTRACT
An infrared camera detects and measures the infrared energy of objects. The camera converts that infrared data into an electronic image that shows the apparent surface temperature of the object being measured. An infrared camera offers opportunity to home in on a suspect zone – where there may not have been visible evidence of an issue – and damp meter as we know also offers that advantage – especially when visible damp damage such as staining has not yet developed. Infrared thermography can be useful to locate underfloor heating leaks when the installation pipework is embedded in screed or leakage from a hot water system. Thermal imaging can be useful in detecting locations of water ingress in insulated flat roofs. The general principle is that water maintains heat once it has penetrated into the roof fabric, and as the surface of the roof cools down, the heat given off by the wetted zone can be mapped by thermal imaging.
