HI SIX1

Thank you for the link very usefull

all i can say is that without heating.

The room grow up from 15° to 19° in 2 hours just with the sun power

It work like a solar thermal air panel.

but it is the room that replace the box of the panel.

off course is the curtain is completly black the temp in the room will grow up proportionaly.

but i must keep some light for the room

that is why i choose the curtain

thank you for reading try it its free heating (7$ is the price of the curtain)

HI EVERYBODY

I found another way to improve the efficacity of the black curtain.

lol. the solution is simple i put a silver curtain behind the black curtain at about 20 centimeter of distance.

A Metallic Fringe Curtain Party Foil FOR EXAMPLE WILL DO THE JOB

I effect more solar power will be reflected to the black curtain and keeping the light to go into the room

if necessary a silver wire could be cutted one on two .

what do you about this new idees

do you have solution for improment?
thank you for reading
