Roll Up Side Ventilation System

Side ventilation is the most effective type of ventilation in a Polytunnel. Our roll up side vent system is a cost effective design which allows you to open and close the side according to the weather and the desired temperature you want in your Polytunnel. You can order this system for one or both sides of your Polytunnel. The size of tube (used in the hoop) it is designed to fit is shown and the hoop spacing is 2m – if you have a different size of tube than shown or a different hoop spacing we may be able to amend the parts and adjust the price accordingly. The winder included is a very simple manual gearbox. A motorised and automatic version will be available soon. The price shown is for one side. It is recommended to also order base rails when getting side ventilation so the system can close down to a flat surface.
