Thermal Building Surveys

Building Thermal Surveys

Thermalplus is a specialist provider of Thermographic surveys and thermal imaging services. All our Thermographic services are available to the residential and commercial property industries.

Thermographic surveys of buildings are typically carried out in the winter months when building’s heating system is operating and there is a suitable internal-to-external temperature difference. To limit the effects of solar gain, building surveys are carried out at night or the early hours of the morning to ensure any radiation from the sun has suitably dissipated avoiding unreliable results from the survey.

To achieve a reliable result from the survey, preparations need to be made to ensure the building fabric has been sufficiently heated and that there is a minimum internal–to-external air temperature difference of 10°C both prior to and during the survey. To achieve this, the heating should be in operation a few days preceding the survey to heat through the building fabric.

On the day/night prior to the survey, the heating should be set to run constantly throughout the night at a temperature that will achieve a minimum internal–to-external air temperature difference of 10°C. To assist in maintaining the temperature difference throughout the building, all windows/doors should be kept closed as far as is practical prior to the survey.

Our surveys and reports enable you to ascertain the following?

• Full envelope inspection and assessment between internal and external areas.
• Thermal indexing to help identify areas of excessive energy loss with the use of Isotherms on the thermograms at external/internal threshold temperatures
• Severity grading of faults found
• Fault pages to include Anomaly, Root Cause and Remedial suggestions
• Full suite of thermal images supplied unencumbered by isotherms at common scale for easy comparison between areas.
• Provision of direct comparison between pre and post remedial work on the same trend page
