While plastic may not seem to be an efficient, effective, or durable material for use in the construction of a greenhouse, plastic in the form of UV Treated Polycarbonate is ideal.

One of the newest glazing options, UV Treated Polycarbonate is a rigid plastic which provides much of the clarity of glass but is stronger and more resistant to impact than other glazings. Polycarbonate can withstand impacts by hail, strong winds, rocks, and even baseballs. Polycarbonate comes in multi-wall panels with many structural walls separating its two flat sides (looks similar to cardboard in design when viewed on edge). This structure gives it greater strength and superior heat retention with the insulating air space built into the product. Multi-wall polycarbonate also provides your greenhouse with an even, diffused light which is optimal for growing plants. Another advantage of polycarbonate is its long lifespan.

[A] - The first picture shows light passing through a clear covering. This type of covering does not diffuse light well and causes sharper, darker shadows to appear. This is less optimal for growing plants, but it is great if you want a clear view of the outside.

[B] - The second picture shows light passing through a diffuse covering like multi-wall polycarbonate. When light passes through, it scatters and causes shade to be "lighter". Plants in the shade receive more total light. This creates better growing conditions for the whole plant.
