Commercial & Institutional Greenhouse Design,

Through the use of standard structural parts, modern production line fabrication, and simplified erection techniques, Janco commercial greenhouses may be built independent of other construction.

They can also be attached to existing structures at one or both ends. They may be erected as gutter connected. Janco commercial greenhouses are also the favorite in public institutions, schools and colleges, agricultural stations, industrial research laboratories.

Janco Institutional Truss House & Gutter Connect Growing Greenhouse Standard Models for larger scale projects

Janco Truss House greenhouses are also the favorite in public institutions, schools and colleges, agricultural stations, industrial research laboratories, and sewage treatment plants to enclose sludge beds.

These institutional greenhouses are designed similarly to the truss types except the trusswork is replaced by rigid aluminum bents. These bents are available in sizes ranging from 4” I Shapes to 12” I structural shapes (span up to 64’).

The advantages of the rigid frame over the truss style are the following:

1.       No trusswork: this results in a minimum of framework and structural memebers, considered by many architects to be more aesthetically pleasing in appearance.

2.       Eaves may be straight or curved.

3.       Rigid frame allows for lean-to or even-span construction.

Complex shapes, such as octagons, hip roofs, or multi-sided structures are possible and practicable with the rigid frame system.

1.       Special designed structural parts.
