Thermography is the use of infrared imaging and measurement camera to “see” and measure thermal energy emitted from an object. Thermal, or infrared energy is light that is not visible because its wavelength is too long to be detected by the human eye, its part of the electromagnetic spectrum that we perceive as heat. Unlike visible light, in the infrared world, everything with a temperature above absolute zero emits heat. Even very cold objects, like ice cubes, emit infrared. The higher the objects temperature, the greater the IR radiation emitted. Infrared allows us to see what our eyes cannot. Infrared Thermography cameras produce images of invisible infrared or “heat” radiation and provide precise non-contact temperature measurement capabilities.
Insulation deficiencies can be detected by Thermal Images by observing the thermal pattern on a given surface. From the outside of the heated structure the warmer areas detected suggest possible or under perfoming insulation.
Moisture in building materials can destroy structural integrity and nurture fungal growth. The first step in moisture problem remediation is quickly and accurately locate and remove all sources of moisture. Infrared thermographic cameras assist in moisture intrusion inspections. The infrared camera detects temperature differences, known as anomalies, which is helpful in detecting water inside wall, under flooring, hidden in ceilings, and other unseen locations in fully finished structures. Infrared cameras instantly show you what’s wet and what’s dry. IR cameras can instantly find the ultimate source with little or no physical disassembly of the premises and minimal disturbance of inhabitants.
Air Leakage also know as Air infiltration-is unwanted amounts of outside air entering the house through cracks and small openings. A leaky house allows moisture, dust, and allergens into the home, making it unhealthy. As air pressure changes in your home, these same leaks also heated air to escape outside..
Methodology and Limitations
The use of the thermal imaging camera has certain limitations. It does not detect all moisture related conditions behind concealed surfaces. Specifically, it detects differences of heat on the surface of most building materials such as floor coverings, gypsum wall board, wood paneling, and lumber. As building material heats up and cools down, dryer materials change at a different rate than wet materials. This creates a difference in surface temperature and will be rendered on the camera. Furniture, certain floor coverings, personal storage items and other materials obscuring walls and floor will inhibit the visibility of the camera and therefore limit the diagnostic use of this device. The use of this device does not CONSTITUTE A WARRANTY, OR AN INSURANCE POLICY THAT MOISTURE DOES OR DOES NOT EXIST IN EXCESSIVE AMOUNTS
How to read report
The colors at the top of the scale represent higher temps as the colors near the bottom
indicate lower temperatures. This report is of qualitative nature so exact temperatures
are not measured. The only observations we are making is that of temperature change and
