Open Roof Greenhouse
|WHY ROUGH BROTHERS?|
By working closely with you, we can help you select, construct and maintain the optimal structures and systems to meet your needs. Whether you are expanding your growing range, giving your garden center a fresh look or just starting out, Rough Brothers' experience is second to none. Our people are a diverse group; backgrounds include engineers, educators, garden center managers, and growers, all working together to help you reach your dreams. From thermostats to computer-driven environmental controls or hand-watering to Ebb and Flo, we can help you determine your needs.
The use of growth regulators is decreased as the design of the Open Air allows the environment to harden and condition your crop, resulting in less damage when shipped, improved longevity on the garden center bench, and increased performance in the garden.
Multiple glazing systems are available: glass, double poly, 8mm twinwall or 16mm twinwall. Venlo style peak offers easy reglazing when glazed with double polyethylene. The rack and pinion drive system minimizes maintenance. Standard and custom widths are available; standard widths are 24' and 36', and the Open Air is available in various heights to accommodate your needs. Complete design specifications and structural details are available.
The standard widths of the Open Air structures are 24'-0", 36'-0" and 42'-0" wide. Custom widths are always available. The structural details below are based on a 24'-0" width.
A cast post top with an integral drip gutter support will bolt to the post and support the gutter saddle.
A galvanized steel gutter saddle will be at each post to splice the gutter and to bolt to the post top. The seal between the gutter saddle and the gutter is created using a black "puttylastic" strip.
Cast aluminum downspout is used where downspouts are required. The hole in the gutter is predrilled for ease of installation of the downspout.
There are many options in the gutter extensions depending on the situation:
- Open ended to let the water run off the greenhouse
- Welded end with no downspout
- Welded in with a downspout
At each interior post there will be a bar joist which shall span across the structure at 12'-0" centers. This not only strengthens the structure substantially, it also provides simplified installation of additional equipment such as:
- Hot Water Heating Systems
- Shade and Energy Curtains
- Watering Booms
- Hanging Basket Systems
- Glass house- aluminum extruded glazing bars with white PVC capping
- 8mm polycarbonate house - aluminum extruded glazing bars with white PVC capping
An aluminum extruded profile which fastens to the roof bars and closes the roof to the top gutter. The closure allows cracking of the open roof during adverse weather conditions.
Galvanized steel frames are used at 12' 0" centers to support the drive shaft and support the roof gutter.
Rack & Pinion
A positive drive system shall be used with an easily understood and maintained rack and pinion drive system. Racks shall be spaced on 12' 0" centers.
Each zone will be driven with a single drive motor with a gearbox at each peak. The drive motor will have a variable frequency drive to allow the roof to close quicker than opening.
