Coverings for Greenhouses, Structures & Growing Spaces

We have polyethylene plastic film, polycarbonate sheeting, shade cloth, and more for work, home and garden. Greenhouse coverings, whether plastic or fabric, are vital for any growing structure.

Using the correct coverings on greenhouses and gardens will provide plants with much-needed protection and the ideal amount of sunlight to thrive. With these greenhouse coverings and accessories, you can build a customized growing space, upgrade your current structure or make repairs and modifications.

Greenhouse Megastore stocks a variety of covers for commercial or hobby growing. Our greenhouse polycarbonate sheets offer the highest level of insulation and shielding against cold weather, rain, wind and more. Choose clear, translucent or colored panels to control how much light gets in.

For budget-friendly protection on temporary structures or in regions with less extreme weather, use acrylic sheets and polyethylene overwintering film on your greenhouses and high tunnels. If you just need to block sunlight during scorching summer months, use greenhouse shade cloth for buildings or hang shade sails over gardens and pergolas.

All our greenhouse covers are available in many sizes, shapes and thicknesses for a customized design. We also have all the greenhouse cover installation hardware you’ll need, including screws, tape, clips, spring locks and bungee cords.

We have served horticulturalists for over 30 years who want to extend the growing season and cultivate their favorite plants. Our high-quality garden coverings and parts come from leading brands, and we back them with a Price Match Guarantee and a one-year limited warranty.
