Radiant glass wall for space heating and cooling

CoolingheatingRadiant glass wallSpace heating coolingtemperature controlThermal break


The invention consists in using large glass panels (made by coupling a single glass placed inside the room to a double glazing) as a system for heating (in winter) and cooling (in summer) the environments, exploiting the structural capabilities of glass elements inserted as spacers between the glass panels, thus creating a cavity inside which heated or cooled air will be introduced according to needs. The wall thus shaped can be dimensionally modular, like the system connected to it.

Technical features

The invention consists of a “glass wall” even of large dimensions (for example 3m x 2.7m made by coupling a double glazing placed outside (double chamber – three glasses), a glazed mirror (single glass) arranged inside of the environment of the same size as the external double glazing. The union between the two glass panels takes place by means of glass spacers (or other material) that create an air chamber between the double glazing placed outside and the glass panel placed inside, forming along the two vertical sides of the wall glazing some ducts into which the heated or cooled air is introduced, heating / cooling by convection the glazed mirror that overlooks the interior of the room, and then being sucked along the channel on the opposite side. The glazed surfaces (external double glazing and internal glazed mirror) are joined along their entire external perimeter by a fixed frame that incorporates both mirrors to allow the glazed wall to be fixed between two floors (or on other boundary walls). TRL: 4.

Possible Applications

  • Constructions;
  • Buildings.


  • High structural rigidity that allows the use of large double glazing;
  • No need for insertion of pipes and conditioning systems inside the “glass wall”;
  • Flexible modular system (roofs and sloping facades, glass walls, anchored panels);
  • Structural thermal break.
