A friends flat is overlooked by other flats and they want to put up some japanese type opaque paper and also some reflective film ( the type you can look out of, but people looking in only see a silvery reflection) on to the window glass.
Could greaseproof cooking paper be used instead of japanese paper (since its probably a lot cheaper) and if so what would be a way to stick it to the glass so that it could be easily removed?
Would anyone know where in London the reflective film can be bought? Thanks.
