We offer string reinforced polyethylene sheeting in a variety of mils and sizes. Reinforced poly is made from high strength film with tear resistant internal scrim. This plastic sheeting remains flexible in cold weather climates due to the string body. It is also highly tear resistant in applications where rips and punctures are a concern due to the extra support of the scrim. It is commonly used to reinforce storm windows because even if the window blows out, the sturdy and abrasion-resistant poly will hold the gap. It can be used as a tarp, as a weather barrier, for construction and painting jobs, and much more. There are seams throughout the poly sheeting. This is not waterproof. Poly can vary in size plus or minus.
