does radiant barrier spray work?

Question

Do you have it and have you noticed a difference in energy bills?

Answer 1

it's ceramic dust added to the paint & you spray the back side of the deck!
I remodeled my cousins house, & he was mad about his e- bill, i told him 3 choices, ice house roof & cool ply ( 2 x 2"s applied over rafer on top of existing deck ), 4 x 8 sheets of foil faced denny board shot to the back of rafters, or spray on!

it's supposed to be 80% as good as cool ply / tech shield / polar ply!!!
