Whats the difference between “Foil” and “Poly?
Single Bubble Foil is also called Foil/Bubble/Foil, because it’s made up of a layer of bubbles sandwiched between two layers of foil; Single Bubble Poly is also called Foil/Bubble/Poly because there is a layer of white poly replacing one of the layers of foil. And of course, the same is true for the Double Bubble products. We also call Concrete Barrier “Bubble/Foil/Bubble.
