These Thermal Images show the relative surface temperature. Blues and Purples are relatively cooler than the Oranges, Reds and Whites. The exact temperature is not really an issue here, the relative temperature is.

This is an unfinished basement wall, showing heat loss. The Blue area is above ground outside. The green and light orange is above the frost line.

These two images demonstrate a significant heat loss. Basement wall insulation is not a standard for new homes in this area. A significant savings is available.

 

 

 

Air Movement copyThis Image is a door. First you notice the trim around the opening. Over the top of the door there is a classic thermal signature of air leakage. The relatively cooler air is being pulled across the drywall.  It is described as a feather pattern. The relative temperature scale is there. Reds are relatively warmer than greens and blues re relatively cooler. You can also see the gap between the door and the frame. This looks like air moving. It isn’t.  The technical term is boundary layer.  It shows up in the IR image as relatively cooler because the air in the gap is still. You will see this in corners, and other recessed areas.  The slot in a screw head is another.
