Photo shows cross section cut of two aluminum
prime window frames subjected to dry ice temper-
atures in a studio with average room temperature
and humidity. Right side illustrates a problem with
most metal window frames - freezing and con-
densation in the interior of room. Left side illustrates
De VAC's designed solution (patent pending). A
red thermo-barrier which insulates the frame and
under all but extreme conditions solves the problem
of condensation and freezing within the room.
