Solar Heating Drapes with Grommets (6' x 9")

Now your sunlit windows at home, in your RV, boat or camper can be transformed into giant solar radiators with our new interior window Radiant solar heating drapes. This deep black, heat and UV resistant HDPE (high density polyethylene) plastic fabric specially designed to absorb solar energy and efficiently convert it to heat. These are not blackout curtains. Filtered sunlight will enter the room and the outdoors is visible from the inside during the day. When positioned near a glass surface, peak midday temperatures as high as 130 degrees F degrees are generated and radiated back into the room as long as direct sunlight touches the heat absorber surface.

By heating the glass and fabric well above the ambient room temperature, heat can't escape out the windows and they both become perfect thermal barriers to help keep room temperatures warmer. Hot always travels to cold, so the radiant heat inside the room is absorbed by cooler walls, the floor and furniture, and is stored for release back into the room when the temperatures drops.

Also, most or all moisture condensation on the glass is eliminated on solar drape covered sunlit windows, reducing window frame damage and mold formation on the frames.  The drapes can be cut to fit any window size and attached with wall mounted hooks, hung on curtain rods, or hung from the included suction cup hooks that attach to the window glass.
