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.
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.
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 area
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 edge.
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 exorbitant.
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.
