VEVOR Greenhouse Plastic Sheeting 10 x 40 ft, 6 Mil Thickness Clear Greenhouse Film, Polyethylene Film 4 Year UV Resistant, for Gardening, Farming, Agriculture, Garden

I have 2 large hoop greenhouses. I am trying to find something that I can put under the top plastic covering, but on top of the metal frame for keeping them warmer. Would this item work for this purpose?
