Infrared Thermography to Building Envelopes

Infrared Thermography to Building Envelopes

Infrared thermography is a diagnostic survey that can be undertaken on both commercial and residential building envelopes.

APT Sound Testing has been using thermography successfully to examine electrical systems and building envelopes for more than 15 years. What makes it such a versatile diagnostics solution is that it allows for non-destructive testing with a high rate of accuracy. It only takes a matter of hours to perform a thermographic building inspection and identify all existing and potential problems with its envelope system and supply a detailed report to the customer.

The aim of the thermal analysis is to help quantify building sustainability and save ongoing building energy costs that are increasing year on year. The thermal imaging survey can help to identify damaged insulation, air leakage paths and HVAC & electrical failures which can lead to heat loss and/or building downtime.

Here at APT we try to be at the forefront of advanced predictive maintenance technologies. That means we have everything it takes to perform thermal imaging inspection latest high-resolution thermal imaging equipment. Its key applications include:

              1. clear visualisation and reportage of energy losses
              2. examination of thermal bridges in insulation
              3. analysis of HVAC systems
              4. checking doors and windows for infiltration/exfiltration issues
              5. detection of floor leaks and moisture build-ups
              6. detection of flat roof leaks
              7. identification of mould growth
              8. assessment of the overall building condition




The importance of using one of our Level 3 trained thermographers cannot be understated as they are trained to be write predictive maintenance and inspection practices and to develop test procedures and ascertain severity criteria. To try and help clients prepare for the thermal imaging survey to their building, we have written the following article: How we carry our thermal Surveys on commercial buildings.


Why pick APT to undertake your thermal survey?
Please note that our thermography engineers are trained to level 3, which is the highest level you can achieve as a thermographic engineer. We also use large format thermal imaging cameras; this provides you with the absolute best chance of solving any potential issues by utilising thermographic technology.

Please contact APT Sound Testing for a free quotation for a thermographic inspection. All we need are a few details such an elevation drawings, floor plans and location to provide a quotation. Once the information is received we will carefully look at the drawings the easiest and most cost effective way to undertake the thermal imaging inspection.

We will also send across our informative Air Tightness Checklist and Thermal Survey Checklist to help you prepare for the thermographic Inspection.
