cheap way to block sun from windows?
Think I know what your talking aboutIt's called Glaser Silver Can upload the pic of it, but google it to see if thats itAn if it is the round then Yes it's for home defenseBut VERY HIGH in price.
Very cheap, but not so attractive ways of blocking sunlight from windows: black garbage bags and blue painter's tape duck tape and tin foil aluminum foil and scotch tape Other ways of blocking sunlight from windows: Blackout window covers blinds heavy drapes Hope this helps and good luck!
