Features of Polycarbonate Greenhouses

We prefer polycarbonate greenhouses for several reasons. First is the durability of the panels. Second is the higher insulation value you receive from the polycarbonate vs glass. Twinwall polycarbonate is like looking down the wall of a cardboard box. It has a sheet on the inside, a sheet on the outside, and a rib running through the center of it. The rib in the polycarbonate sheet is straight, rather than wavy like corrugated cardboard. But, the rib will distort your view. You will be able to see color, but not form through the ribs. Honestly, this is the only downfall we can think of to twinwall polycarbonate greenhouses. That is why we offer some of our polycarbonate kits with a clear, see through polycarbonate for the sides. For better growing conditions, our top choice is a polycarbonate greenhouse.


The Chalet greenhouse has the old wordly style of an orangerie. With a powder coated aluminum frame, a large double door, clear polycarbonate sides and a twinwall polycarbonate roof, this greenhouse has all of the most desirable features.


The Americana has a gambrel or barn shaped roof. This greenhouse also has a much appreciated double door. This is great for bringing in larger plants or wheelbarrows. WIth crystal clear polycarbonate sides and a twinwall polycarbonate roof you get added insulation with a clear glass like view.
