      Polycarbonate Panels for Greenhouse Construction

      Polycarbonate is one of the most popular and durable materials for greenhouse building. Clear polycarbonate sheets give growers strong, lightweight protection while allowing excellent light transmission for plants. Whether you’re a commercial grower or a backyard gardener, our selection of polycarbonate greenhouse panels offers the clarity of glass with far greater strength and insulation.

      Why Choose Polycarbonate Sheets

      Polycarbonate is up to 250 times more impact-resistant than tempered glass and provides outstanding thermal insulation. It’s easy to cut, drill, and shape, making it ideal for custom greenhouse designs, roofing, windows, and sidewalls. Our twinwall and multiwall polycarbonate panels help maintain even growing temperatures and diffuse sunlight for healthier plant growth.

      • Twinwall Polycarbonate Panels: Two-layer sheets that trap air for excellent insulation and energy efficiency.
      • Multiwall Polycarbonate Sheets: Extra layers increase strength and thermal performance for larger or colder-climate structures.
      • Clear, Opal, and Diffused Options: Choose your preferred level of light transmission and diffusion for your plants’ needs.

      All of our polycarbonate panels are UV-protected to prevent yellowing and degradation, ensuring years of clarity and strength. Panels are available in multiple thicknesses, widths, and lengths to fit any greenhouse or outdoor project.

      Trusted Source for Greenhouse Polycarbonate

      For over 30 years, Greenhouse Megastore has supplied high-quality polycarbonate sheets to builders, growers, and hobbyists. These versatile panels can be used for greenhouses, sunrooms, carports, pergolas, patio covers, and more.
