This 20 x 28 ft greenhouse film gives you a wide sheet of 6 mil polyethylene to cover a hoop house, cold frame or raised garden bed. It's engineered to resist tearing, corrosion and UV breakdown, so it keeps doing its job season after season instead of cracking or clouding over. The film traps warmth during chilly nights and shields plants from intense UV exposure in the heat of summer, while also reducing dust that would otherwise settle on leaves and block light. Because setup is do-it-yourself, you can stretch it over a frame you already have without special tools or professional installation. When it's not stretched over a garden structure, the same durable sheeting works as a protective cover for construction sites, masonry work and landscaping projects, giving you a tough barrier wherever you need one around the yard or job site.
