I recently rented an infrared camera to help identify opportunities for reducing the cost of heating and cooling log Homes. Here are a few interesting photos.

When interpreting the photos, be sure to compare the temperature vs. color scale at the bottom of each photo with the colors in the photo.
The temperature outside was 30 – 35 degrees F, inside 72 degrees F.
The instrument was a FLIR-i7.

Infrared photo of a window.

(Figure 1) -This is a twin, double hung window unit. The unit on the left is covered by a black-out, honey comb shade. Wow! What a surprise.
Also note the purple window frame. The window is, double pane, all wood frame, aluminum covered exterior but no argon gas fill. Infrarea photo of a houble window unit in a Log home bedroom.

(Figure 2) – Argon filled, double glass, vinyl frames. looks like the good news here is the Argon gas fill between the panes.
While we are on windows, click>> Milgard Windows for additional proof of these energy efficient windows. Close the pop open web window to return here.
Infrared pictures of fixed glass windows in a Log home great room.

(Figure 3) – These fixed glass, double pane, units were made in a local glass shop. The walls between the fixed glass are 2″ x 6″ stud construction with 1″ x 6″ T&G inside, Log siding outside and fiberglass insulation between the studs. Infrared photo of cold air leakage through a Log wall.

(Figure 4) – Air infiltration through the Log wall. In the corner, obviously cold air infiltration. Regarding the air leakage at the floor, it is likely that sill sealer was not used during the construction of this Log home. Get out the caulking gun! Remember, the small stuff can make a big difference in your dream Log home.
Cold air leakage around a recepticle

(Figure 5) – A standard duplex receptacle in a Log wall. Cold air leakage around a GFI recepticle in a Log wall.

(Figure 6) – This is a duplex, GFI receptacle, in a Log wall. Question: Is the heat generated typical of a GFI unit or is there a loose wire inside? Also, more air infiltration above and below the receptacle
A 3 second infrared hand print on a french door in a Log wall.

(Figure 7) – Just for fun. A three second hand print on glass, invisible to the necked eye. Insulation batt set 6 inches apart in the great room ceiling of this Log home.

(Figure 8) – Sloppy workmanship! Insulation bats in the great room ceiling are separated by about 6″.
