Wire penetrations are extremely common. We air seal them with spray foam to prevent future air leakage. Using the infrared really magnifies the area where heat is escaping into the attic. The yellow area is the hole and the area around it is nearly 60 degrees on a 10 degree winter day.
The picture on the right is another wire penetration. You can see that the hole is much larger than the actual wire. The picture on the right is the infrared and shows that area around the hole at roughly 63 degrees on a 10 degree day.
The right picture is loose blown insulation. There is not nearly enough there, as is seen in the picture on the left.
This is another area of the house where the blown insulation is not nearly thick enough. The infrared shows nearly 70 degrees in this attic on a 10 degree day.
This is a top plate in the attic. Drywall is visible, with no insulation over the top of it. It may not look like much, but with an infrared camera we can clearly see that the surface temperature is over 55 degrees on a 10 degree day.
Many different steps go into our energy evaluation process. People are always asking about the different steps, and more specifically how we actually uncover problems within a home. An infrared camera is an invaluable tool our Energy Management Consultants use on a daily basis to uncover otherwise invisible problems.
