Not all plastic is created equal for this. We recommend using Opaque, 6-10 mil string reinforced polyethylene. The opaque feature will reduce the amount of condensation when compared to clear sheeting. Remember, Opaque can mean white plastic. Often people hear the word, opaque and think of black plastic. A white film will reflect the sun while a black film will absorb the heat.
