Thermography Inspection


Thermography Inspection

  • Thermogarphy Inspection on new buildings compliant with Part L of the building regulations and BS-EN 13187.

  • Thermography Inspection to detect air leakage that is causing heat loss from older buildings improving energy efficiency in your home or business.

Thermography Inspection scans detect temperature variations in the shell of the home or business, which helps determine whether air is leaking and heat is being lost. The most accurate thermography inspection device is a thermal imaging camera, which produces a 2-dimensional thermal picture of an area showing heat leakage. Thermography inspection is non-invasive and non-destructive: no walls, floors or ceilings need to be opened to perform the inspection.

Reducing the amount of air that leaks in and out of your home or business is a cost-effective way to cut heating and cooling costs, improve durability, increase comfort, and create a healthier indoor environment.
Air Tightness and Thermal Imaging testing are important quality control measures when building or renovating a house. Heat losses in buildings can account for up to 50% of the total energy consumption and comes from air leakage through chimneys, attics, wall vents and badly sealed windows / doors.

Adequate air exchange is essential for the occupants’ health and safety, but most buildings have a far higher rate of air exchange than is necessary. The root cause is often poor design and/or construction which allows air leakage from the outside to the inside of the building, or the opposite. The leakage pathway is often complex and, without thermal imaging, extremely difficult to visualize. This also allows the contractors to quickly identify and repair the problem areas to stop the energy loss immediately.

All new buildings must meet air tightness requirements of the Building Regulations. By reducing air leakage, you will obtain a better comfort in the building. The building can also be heated more efficiently to conserve energy and save money.
Poor or inadequate insulation, moisture, building envelope leaks, and substandard work are costly to residential and commercial building owners. A Thermography Inspection can help you quickly see where energy efficiency can be improved.

Air infiltration contributes about 10% of the heat loss in a typical house built in the late 20th Century. Airtightness testing is a requirement of Part L of the Building Regulations unfortunately it does not identify the location of the air leaks that are limiting the airtightness. Thermal imaging can clearly show these leaks in a depressurisation test provided that there is a temperature difference of at least 5 oC at the time of the test, so the two are complementary.
Thermal imaging is therefore a useful diagnostic tool in tests on new buildings, but it can also be used to detect air leakage that is causing heat loss from older buildings. Although a blower door is typically used to provide the pressurisation it is possible to use the effects of wind, which typically pressurises one side of a building that leads to air entry at low levels and exit at high levels in tall buildings.

Leak Detection Specialists Thermographers are certificated at all three levels by PCN, part of the British Institute of Non-Destructive Testing (BINDT). Our thermographers use their skill and experience to interpret thermal images and diagnose any anomalies in the construction, compliant with Part L of the building regulations and BS-EN 13187. Leak Detection Specialists use leading-edge infrared technology from FLIR to perform thermography inspections of homes and buildings to improve energy efficiency, thus leading to savings on energy costs.
