Agro Invest Holland B.V. has years of experience with the construction of composting facilities for phase I, II, and III.
In the traditional system, the growing cell was “built” in a building. With the new system, the ceiling of the growing rooms and the roof of the building are comprised of the same element. This element is a 200/250-mm-thick steel-sandwich panel. The core of this panel is a 200/250–mm-thick insulated sheet of extruded polystyrene with a fire-retarding quality. The topside of this panel has a roof sheeting of 500 μ PVC. This layer has a gray color to prevent the reflection of heat from the sun. The Rc-value of the panel is 5.3 m2K/W, which is an extremely high insulation value.
The advantages of this system are that the trusses, purlins, roof sheets, and gutters can be omitted. The panels are of a very high quality and do not need a lot of maintenance. Furthermore, there are no thermal bridges and the construction is a lot faster and cheaper to build.
Both the traditional and the new flat-roof system can be executed with the tray-and-shelf system. The systems can be adjusted to accommodate mechanical and manual harvesting. Furthermore, you can choose between concrete and sandwich panels.
Agro Invest Holland has developed a computerized air-handling unit. This system ensures the optimal control of the climate in the growing rooms.
