Thermal Image

Thermal imaging tests from the Passive House Institute (PHI) in Darmstadt, Germany, demonstrate that there are no weak points of conduction through the window system. The imaging shows that all of the interior surfaces of the window (the frame, casements and glazing) are warm, even at the glass edge. The temperatures of the interior surfaces varies only slightly from the surrounding temperature in the room, both in summer and winter temperatures.
