Infrared Thermal Imaging

What is infrared thermal imaging?
An infrared camera measures and reports temperature variations that are reflected from the surfaces of materials. This tool can be useful for detecting conditions that are not able to be seen by visual inspection such as hidden moisture in walls or missing insulation at windows.

Infrared thermal imaging is commonly used in building inspections because the process is non-intrusive and does not require cutting into or damaging the walls or ceilings. This greatly reduces the time and cost of determining actual as built building conditions.

What can infrared thermal imaging detect?

Correctly calibrated by a trained professional, an infrared imaging inspection can be used to detect:

  • moisture intrusion
  • insulation installation verification
  • air leakage or infiltration
  • thermal energy loss
  • missing grout in CMU walls
  • leaking water piping
  • roof waterproofing
  • thermal bridging of building materials
  • likely areas of mould growth In addition, because the infrared camera can measure temperature difference, it is useful in determining the heat loss or gain in a building and assisting in thermal energy audits to reduce energy waste.

How is an infrared imaging survey conducted?
Typically the initial survey takes one day. Exterior infrared thermography is best when conducted in the early morning or late evening when indoor and outdoor temperature differences are greatest. An interior infrared survey for moisture intrusion or mould growth conditions can be conducted at any convenient time.

How much does it cost?
Infrared survey costs will depend on the size of the property and complexity of the building however fees are consistent with other professional technical services.
