Abstract
Abstract The invention relates to a fireplace screen system which includes a single and/or multi-section fireplace screen made of one or more glass panels which are laterally spaced apart to provide a heat and insulation barrier construction. An air blower assembly communicates with the interior space between the panels for circulating air heated by the fireplace into the surrounding room area to be heated such that the system provides a heat barrier and insulation when the fireplace is not in use and provides a heat transfer structure when the fireplace is in use.
