Hi , this is going to sound daft but..
I need to keep the heat in (it's cold outside)
I need to keep the window open.
there is a small 30cm satellite dish on the window sill I need for sky digital (the tv reception here is appalling - dreadful - you can barely make out the shapes on the screen)
This dish is realy really small - unbelievable
With the window open , how can I keep the heat out.
Are there any really 'heavy' curtains or anything.
Incredibly, despite the temperature difference it's not *too* bad.
I use a sheet of fabric to cover the hole in the wall (light proof curtain lining from john lewis).
As well as that I draw the curtain.
Any suggestions please?!
