Polytunnel Roof Vent

Please note, we're currently awaiting stock which we expect to ship Mid-March.

Easy to install roof vent, with simple pull-cord operation.  Used to release excessive heat build-up in your polytunnel without having to open the doors.  The spring closing design allows it to be closed tight shut when ventilation is not required.  Useful in longer polytunnels where heat can build up in the middle, or when the doors need to be closed.
