ABSTRACT:
The portable fireplace screen unit comprises a glass panel of sufficient size to close the typical fireplace opening. Screen panels are hingedly connected to the opposite side edges of the glass panel. When the screen panels are angled toward the fireplace and the glass panel spaced away from the fireplace opening, air needed to support combustion readily flows through the two perforate screen panels as well as over the top of the imperforate glass panel. When the screen panels are angled in an opposite direction and the glass panel placed against the fireplace, the opening is closed to prevent unnecessary heat loss. The screen panels can be folded against the glass panel for compact storage of the unit.
