Thermal Imaging from Thermal Survey Ltd

Thermal Imaging is a valuable tool for carrying out qualitative assesment of building fabric insulation.

Rapid & Non-invasive surveys enable reinsulation works to be planned as cost effectively as possible.

Following insulation installation, thermal imaging is much in demand to QA check the standard of work carried out.

The following images illustrate some of the capabilities of the technique and the range of problems that can be detected.

On the wall of this prefab, the dark patches represent intact insulation panels, the paler areas, missing or damaged insulation.	The building in the foreground of this factory site, is a boiler house, so the high heatloss is expected. The building behind however, shows anomalous heatloss through degraded insulation.
The house on the left of this terrace is significantly brighter than the others, indicating a higher surface temperature and therefore the state of the wall insulation should be investigated.	The strips of wall insulation in this leisure centre had become disconnected at the top, sliding down the wall cavity, leaving an uninsulated gap, through which the heat escaped.
The bright patch in this image is caused by an underground steam pipe running beneath a carpark. The pipe was uninsulated and as it was serving an unoccupied building, was sealed off after the survey.	This wall clearly has more heat escaping at the bottom corners than elsewhere. The cause was the specified building materials being replaced by cheaper, less efficient substitutes.
