I built one using 1/4 inch window glass.
W= Glass
m-Mylar
AL= AL foil
WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW <-1/4 Window glass 12x20 inch
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm <-was 0.01 inch Mylar
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
AL-------------------------AL <-was 10x6 inch AL foil
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
