20'x96' Quonset greenhouse frames are also known as “high tunnel greenhouses.” The Quonset frame type has a lower peak height making it more efficient and economical to heat. The Quonset frame types are the least visually intrusive frame type.

20'x96' Semi-Gable greenhouse frames have taller sidewalls that reach a higher peak than the Quonset greenhouse frame type. The high pitch allows for better snow shedding and provides the largest interior volume of space per square foot. Semi-Gable greenhouse frames provide easy access, the most usable growing space, and can withstand snow.
