greenhouse cover glazing materials for greenhouses and other structures

The Greenhouse Glazing Materials That Are Right For You!

The best greenhouse glazing materials you can find to cover your project at the most competitive prices anywhere can be found right here. These polyethylene or polycarbonate materials are made by special manufacturing processes, especially for applications that require UV protection from the sun. Polyethylene is a more pliable material than polycarbonate and can follow curves or be installed flat. It is generally less expensive to ship and about one half the cost per sq/ft as polycarbonate. It's double wall design makes the polyethylene strong and durable. Polycarbonate on the other hand is best for applications that require a rigid material that is wider in thickness and has much more strength than the polyethylene. Polycarbonate can also be purchased in clear or bronze as well as in the standard opal color of polyethylene.

THE LIGHT SPECTRUM

Vegetation, fruit, flowers, along with specific coverings for livestock and reptiles, require that certain ranges within the light spectrum are allowed through, while others remain blocked. The light spectrum is a continuous range of electromagnetic radiation waves. It ranges from the longest radio waves to the shortest X-rays and gamma rays.  The electromagnetic radiation wavelength range is called visible light. The visible light wavelength range is about 380nm to 750nm.  PAR, or photosynthetically available radiation, is UVA radiation found between 400nm-700nm and is the portion of the light spectrum utilized by plants for photosynthesis.  315nm -400nm UVA will inhibit mold growth and fungal development, Increase the amounts of THC, CBD, and terpene production in cannabis plants.  Polycarbonate sheets with UV protection will block the harmful UVC and UVB rays while allowing the UVA spectrum through to promote plant growth and allow healthy radiation for reptiles and livestock.
