Infrared Imaging Uncovers Many Concealed Defects - See Images

My infrared camera detects shoddy installation of cellulose insulation in this concealed wall cavity above the door.

wall insulation not complete


Thermal imaging detects insulation gaps throughout this attic floor



Infrared scan detects shoddy insulation application in outer ceiling cavities



This wall set-up looks great, until my infrared camera detects uninsulated wall cavities behind the flat screen television



Thermal imaging detects a wide insulation void throughout this upper wall



Thermally scanning an attic detects heat loss from the living area below



The builder disclosed that all the walls (in this rehabilitated home) were fully insulated. Not according to my infrared camera.

wall insulation not complete

This is an exterior wall with no insulation issues. The structural member locations are clearly visible (with infrared) from colder studs conducting onto the interior drywall.

insulated wall cavities

During the colder months, a perfectly insulated wall will contain cold structural members (see image above). In this home, the studs are warmer than the cavities. This is clearly indicative of "no insulation" behind
this particular wall.

wall missing insulation

This is another home with the same situation...empty wall cavities. This uninsulated wall is equal to leaving your windows and doors wide open.

The attic cavity above this particular ceiling was not accessible. No openings were installed for my inspection. That don't stop me from investigating further. My infrared camera has no problem detecting a shoddy
installation of insulation. The heat loss here would be significant.

This lower ceiling surface looks good visually, but my thermal imaging camera detects an excessive void

This newly constructed home had insulation missing in this corner of the room.

These outer ceiling cavities are allowing excessive cold air to enter living area

This wall looks fine until my infrared camera detects settled insulation

My thermal imaging camera detects more settled insulation

Infrared detects cold air infiltrating at lower left window framing and all outer floor cavities

A client inquired about ice damming on their roof. You can clearly see the voids at the rear portion of these two skylights. This void allows interior heat to escape and melt the snow on the roof above this

The soffit around this particular skylight contains recessed lighting that does not allow insulation contact (Non-IC lighting) per manufacturer. An upgrade to more expensive recessed light fixtures (allowing
insulation contact - IC lighting) are no option, in order to properly insulate
this type of ceiling cavity and prevent ice damming on the exterior roof

The stud cavities around this window were obviously not insulated.

Cathedral ceiling cavities are impossible to inspect visually, but thermal imaging has no limitations. My infrared camera detects missing insulation throughout one side of the gable. The heating bill here will be

The cellulose insulation in these wall cavities has settled quite a bit

More settled cellulose insulation. Infrared also detects heat piping behind this wall at the top right of IR image.

This area appears to be fine, but infrared detects missing insulation

Infrared detects a major leak at radiant heating. System must be abandoned.

Between my busy work schedule and spending quality time with my family... I will attempt to stay actively involved here. Thank you kindly.

Nice images, David! I certainly hope that you will be actively involved in the Infrared Thermgraphy Users Group here on HEP... looks like you've seen a little of everything!
