Quality rack & pinion operated roof ventilation
may be fitted to the rain cover model, with Automatic of manual controls
Pivoting along it’s apex the “guttervent” opens
up one side of the roof for efficient evacuation of warm air & the
introduction of fresh air to the structure. The unique guttervent
design allows the roof vent to be opened approximately one third even in
damp conditions. The design over the ventilator protects the opening
keeping light rain from entering. Long life quality Ridder rack &
pinions are used to drive the ventilator, & these are roll formed
at the Redpath factory into a curve limiting their protusion into the growing
environment. The Redpath vented arch frame & ventilator may be clad
in either inflated Twinskin or singleskin poly Duratough greenhouse film
cladding.
