Building Envelope



The Exterior of the building must be scanned after sunset, allowing any solar gain to dissipate, enabling us to get a true conduction loss through the exterior walls. There should be a temperature differential of at least 20 degrees F between the inside and outside of the building.

The types of heat loss that we will be looking for:

  • Conduction

  • Exfiltration

  • Infiltration

The three areas of a building envelope heat loss that can be detected through the use of Thermography are:

Conduction of heat through a structure enables us to locate poorly insulated areas, insulation voids and moisture within the insulation.

Exfiltration of warm air enables us to locate openings around doors and windows, as well as, construction seam openings, stress cracks in walls and water penetration points.

Infiltration of cold air enables us to locate, from the inside, insulation voids, as well as, air leakage at wall plates and interior wall.
