The Biltmore 14' wide free-standing greenhouse kit has room to grow and then some! With ten standard sizes ranging from 14' long to 50' long, this Turner greenhouse is being used by hobbyists, educators and commercial growers alike. Every Turner Greenhouse kit is easy and inexpensive to construct.
The framework of each Turner Greenhouse kit is made of rugged, and rust resistant Galvalume metal. This coating process is more than twice as resistant to corrosion as conventional galvanizing, making it exceptionally strong, long-lasting and maintenance free. All Turner Greenhouse structures come with a 1 year manufacturer's warranty against defects and workmanship.
In the Biltmore there is ample room to house two 2'-3' wide side benches on each wall plus a bench or potting table in the center. And there's still ample walkway on each side.
In addition to adding extra workspace at no extra cost, the Dutch Design gives you a stronger greenhouse that is more resistant to wind damage, while allowing 26% more sunlight to penetrate because less light is reflected.
We give you three choices in covering material: A heavy duty fiberglass or the more economical polyethylene cover. Our fiberglass is UV treated and especially manufactured for greenhouses and comes with a 10 year limited manufacture's warranty. The 6mils polyethylene, (a heavy duty plastic sheeting), we use is especially manufactured for greenhouses. We recommend replacing polyethylene after 3 to 4 growing seasons under normal conditions.
We now offer the super energy-saving twin-wall 6mm polycarbonate! It is UV treated and especially manufactured for greenhouses and comes with a 10 year limited manufacture's warranty.
 We strongly suggest you add the internal roof support kit to the Biltmore greenhouse. For greenhouse owners in areas that receive snow or live in a windy area, tend to have strong thunderstorms, we recommend this kit which adds twice the additional strength to the Biltmore Series. (To help reduce the snowload, people who live in colder climates need a heat source inside the greenhouse. And if possible, sweeping off excess snow will help). Even though the internal roof support kit gives extra strength to the structure, do not leave a heavy snow load on your greenhouse for long periods of time.....
How does the system work? After concrete piers are installed in the greenhouse floor, posts are attached to the piers with anchors. The posts are then connected to the purlins with braces and special brackets. We provide all the fittings, brackets and fasteners which are either stainless or galvanized steel. All the posts and purlins are precut and made of heavy-wall galvanized steel pipe. The posts are spaced at a maximum of 8' and the purlins run the full length of the greenhouse.In addition to adding great strength to the structure, the posts and purlins are ideal for hanging baskets and extra shelves.While a support kit is more easily installed when the structure is first erected, it can easily be added anytime.
