Abstract: A thermal barrier system for panel installations comprises at least one gutter member attachable to a structure. The system further comprises a face member and a thermally insulative coupler member. The coupler member has an intermediate body portion to which are attached a pair of resilient legs which are rotatable into lockable engagement with a pair of slots defined in the gutter member. A second pair of resilient legs are attached to the intermediate body portion of the coupler member and are configured to snap into locking engagement with a pair of slots defined in the face member. The coupler is disengageable from the gutter and face members by a reverse rotation. Gaskets for engaging a panel between the face member and the gutter member are attached to the face member and the gutter member.
