On average, a window has 10% insulation value of a wall. Many heated buildings and commercial spaces are vacant most of the time, with a big amount of energy leaking through the windows. The company manufactures a ”roll-down wall” that minimises these energy losses. Climate Curtains' ability to harvest solar energy and transfer the heat into the room gives an added bonus.

12. A thermally insulating curtain for a window of a room, comprising: an outer solar-energy-absorbing surface; an inner thermally insulating layer; a transparent layer situated outside of the solar-energy-absorbing surface a space that is at least one of situated between the outer solar-energy-absorbing surface and the transparent layer and situated between the outer solar-energy absorbing surface and the inner thermally insulating layer; an air transport structure configured to move air through the space; and a fastener for arranging the thermally insulating curtain on an inside of the window such that absorbed solar energy is supplied to the room.
13. The curtain of claim 12, wherein the inner thermally insulating layer comprises a plurality of air partitions mutually disposed at a distance from each other and extending parallel to the outer solar-energy-absorbing surface.
14. The curtain of claim 12, wherein the space is open therethrough and includes a thermostat that determines air temperature in at least one of the space and the room and a valve that prevents cold air from being conveyed into the room by cold downdraft.
15. The curtain of claim 14, further comprising a transverse air duct that is disposed at at least one of a bottom and a top of the curtain and that extends from the outer solar-energy-absorbing surface inward toward the room.
16. The curtain of claim 15, wherein the air transport structure comprises an electrically powered fan, and the thermostat determines air temperature in the air space and in the room.
17. The curtain of claim 16, wherein the inner thermally insulating layer comprises flexible layers mutually disposed at a distance from each other.
18. The curtain of claim 12, wherein the fastener comprises a rotatable part.
19. The curtain of claim 18, wherein the rotatable part has a through air duct.
20. The curtain of claim 15, wherein the air transport structure produces convective air flow through the space from the bottom to the top.
21. The curtain of claim 12, wherein the curtain has a circumferential shape and width fitted to an opening and depth of the window.
22. The curtain of claim 12, further comprising a fixed suspension rod disposed at a top of the curtain, the fixed suspension rod having an outlet opening for air, and outlet openings at a bottom of the curtain for air through the curtain.
23. The curtain of claim 12, wherein the transparent layer is flexible.
24. The curtain of claim 23, wherein the transparent layer is plastic material.
