These figures are from an old hydroponics source.  Unfortunately I
know longer have the URL.  These figures, represent  the percentange
of light reflected.

    Mylar 90-95
    Flat white paint 85-93
    Semi-gloss white 75-80
    Flat yellow 70-80
    Aluminum foil 70-75

Note flat white paint is better than semi-gloss.  Does this suggest
wrinkled tinfoil is better than non?

Hope this helps.
