20'x100' NRCS Quonset High Tunnel w/ Truss Reinforcement

Greenhouse frames can be strengthened with truss reinforcement. These packages can be designed to add reinforcement to every bow or every other bow. This is recommended in areas with high wind or snow.

6mil plastic is the industry standard cover for cold frames. It comes in multiple varieties such as 1 year, 4 year, and infrared/anti-condensate.

Our greenhouse frames are made up 2 3/8” sidewall posts (0.095ga), 1 7/8” arches (0.090 ga), and 1 3/8” purlin (0.065ga). 2” square tubing (0.065ga) is used for end wall framing kits include the uprights and horizontal wall pieces required for supports and rough openings. Hardware such as brackets and screws are included.

Quonset shaped greenhouses use less materials than semi gable designs and are best used in mild climates with little to no snow load requirements. They have less air volume making ventilation and climate control less expensive.

We use 2” square tubing for our end wall framing kits. The kit includes the uprights and horizontal wall pieces required for supports and rough openings, and installation hardware such as brackets and screws.

Sliding doors are more resilient to wind than swinging doors. Door kits come with trolley rail, door hangers, door handle, stay roller, and door catch. Note that the cover is not included.

Roll up side walls are a great way to utilize passive ventilation to cool and dehumidify your greenhouse. They can be powered or manual and include a wind retention system.
