Flat Roof Greenhouse

The improved design of the endwall posts eliminates the need for internal and external cable and post bracing. This allows for unrestricted access along the end walls, as well as reduced installation and cement costs.

The end members are factory drilled for suspension wire locations, eliminating suspension wire vise brackets.

The direct drive system, located in the center of the house, eliminates stress on the end walls, thus reducing cable wear at all pulley locations.

The drive system allows for the roof curtain to move in two 15 foot increments between the 30 foot wide post spacing, reducing stress on the motor and hooks

Roof open/close time is only 3 minutes 20 seconds.

The roof fabric, LS PLS40 abri (45 % shade) reflects heat out in the summer while retaining heat in the winter. The factory installed abri wires and outdoor hooks provide additional strength for the curtain in both directions. This enhancement allows for a tighter curtain, reducing the amount of drip locations when the curtain is closed, protecting the crop during heavy rains.

The PLS40 abri fabric, which is knitted rather than woven, lasts longer than traditional flat roof material, while less prone to algae build up. Further benefits of the PLS40 abri fabric is its resistance to tearing and when cut around posts during installation, provides a tight energy seal eliminating heat loss during the winter
