Suggestions: Winterizing the High Tunnel
Using customer-supplied materials, create "H" bracing within the roll-up end panel frame to support the panel
during winter months and strong winds. Secure horizontal support using pins for easy removal. Vertical bracing
can remain throughout the year if spaced according to needs.
Ground Level
For added cold protection below ground, bury
2" foam insulation board down to the frost line
around the perimeter of the building. Consult a
qualified construction contractor
before erecting
the high tunnel
to determine how best
to install the customer-supplied 2"
insulation board.
