PROTECT YOUR CROPS
Adequate ventilation in a polytunnel structure is essential to maintain optimum growing conditions. We provide a range of ventilation options that allow you to choose the most efficient and cost-effective solution that meets your needs. At Polybuild, we can provide the right environment for your crops. With the right ventilation system, you can also extend your growing season.
RANGE OF VENTILATION SYSTEMS
Polytunnel gable end ventilation
Ideal for smaller structures with door openings to each end, allowing a through draft, which is essential on warmer days. For more efficient polytunnel ventilation, a louvre vent panel can also be installed to release the heat that builds up in the upper roof space.
Polytunnel extraction fans
Extractor fans at one end, with auto inlet louvre’s at the other will give a good air movement in the polytunnel regardless of the outside conditions.
Full height or end ventilation
An optional full height 2.5m walk through ventilation system can be supplied on vertically sided polytunnel structures, suspended from a side gutter or the end lintel to allow walk-through access and easy loading of stock as well as efficient ventilation. Operation is via an aluminium roll tube driven via manual gearboxes with a crank handle.
SIDE VENTILATION SYSTEMS
Extra ventilation is essential for polytunnel structures longer than 20m to avoid hot spots in the centre. Side ventilation systems are available as a complete kit that include either a timber or aluminium fixing rail or side aluminium gutters to attach the cladding materials to the frame. Wide mesh netting or windbreak netting is used to contain the roll up curtain.
