The curved rafter "A" frame roof truss improves
light transmission by providing minimal structural shadowing.
Redpath's exclusive use of our registered design
curved rafter “A” frame portal for the Ecoshelter 9200EV design offers
growers a superior edge for their greenhouse crop production. A curved
rafter truss or “cosecant rafter” design is extremely well suited for use
as a greenhouse roof truss. It offers superior environmental control
performance & gives fundamental advantages to lift production when
compared to any other overhead truss design.
A curved rafter portal with its variable pitch
will naturally drain internal condensation speedily to the edge of the
roof line & thus prevent condensation water from dripping onto the
crop whilst also significantly increasing light transmission to the crop.
There is a 50% decrease in Driplines.
The Redpath aluminium gutter lockstrip is fastened
along the side faces of all internal gutters & is positioned to catch
the run off of condensation from the roof sheets & direct it outside
of the greenhouse. By stopping the recycling process within the structure
of it's own condensation a large gain in humidity control is achieved.
