Modern Infrared Thermal Imagers are able to detect the smallest temperature differences on surfaces that the trained Thermographer is able to interpret as thermal exceptions. Thermal imaging is a non-destructive, non-invasive way to find latent probelm areas in buildings fast and effectively. A thermographer needs to be trained and must be qualified to interpret images. This specialized service is provided by Alex Feger with Thermovision when you request thermal imaging services. Detect where moisture is located in your walls, ceiling and floors. This procedure can also provide you with information on areas that are creating energy loss - locations such as ductwork, windows, doors and poor construction methods.
