THERMAL IMAGING
Thermal Imaging
Thermal Imaging basically involves an infrared camera measuring the temperature of the surface it is pointed at – displaying very sensitive variations. In order to detect damp timber and other walls/roof members, the camera will differentiate between the temperature of the wall lining and the temperature of the stud.
The mass of the stud will provide a slightly different wall surface temperature. If the stud is wet there will be further temperature variance. These varying temperatures are converted to an image and displayed on an LCD screen.
Eden Pacific (NZ) Ltd can offer the use of Thermal Imaging as an addition to your pre purchase, pre sale or moisture assessment.
As a non-destructive detection method, using an infrared camera has a number of advantages over other methods, and a few disadvantages.
On Site Inspections
- The method is quick
- It is a non-intrusive means of investigation
- Does not require relocation of the occupants
- Features an illustrative visual presentation of findings
- Confirms failure points and moisture migration paths
Disadvantages of Thermal Imaging
- The method only detects surface temperature differentials and can not see through walls
- It cannot detect subsurface damage.
- Results can vary dependent upon on site conditions.
