Abstract
In a series of insulated panel members an interlocking labyrinth seal is provided to minimize the heat loss, the seal having a pair of first slots for receiving a U-shaped clip, a pair of second slots for receiving an offset spacer, and a plurality of right angle flanges for locking the offset spacer into the second slots. Insulated panel members are placed in end-to-end relationship and locked together when the U-shaped clip is inserted into the first slots and retained in position by an undercut slot. Heat loss through the seal is minimized because slots in the spacers expose insulation material into the area where the heat loss can occur.
