Here are two infrared scans were taken at night of two individual houses. Environmental conditions were identical for both with an outside temperature of 24 degrees Fahrenheit. Both photos were taken in the evening. The photo at right is of a two-story home conventionally built with wood and fiberglass insulation. The photo at left is a single-story home built with NETZERO SIPS 4″ R-24 wall system. The scale to the right of the scans represents temperature, with the red representing warmth and the blue representing cold. As you can clearly see, there is a stark difference between the two photos.
The photo at left shows the NETZERO SIPS’ wall without studs and fiberglass and without noticeable heat loss. The outside wall temperature is close to that of the outside air temperature. There is no readable thermal loss in the NETZERO SIPS’ wall.
In the stick-built home, one can clearly see the 2×4 studs 16″ on center as represented by the colored lines and the fiberglass insulation as represented by the pink. This photo shows a tremendous amount of heat transfer/loss (and money loss) to the outside of the walls. This transfer can be seen in both the studs and the fiberglass, with the studs representing greater heat loss.
