As temperatures drop and summer heat stress fades, farming priorities shift. Keeping dairy cows and youngstock safe from heavy rain and severe gales becomes a priority. However, getting your winter livestock ventilation right is essential – you still need steady fresh air moving through the shed to prevent respiratory issues and environmental bacteria.

Choosing how to enclose your shed is one of the most important decisions you will make ahead of winter. At Intershape, we supply a wide range of options – from simple, heavy-duty choices like the Vervaeke Fixed Windbreak and the Secure Windbreak System, to adjustable options like the Airkoe Safe System and the Vervaeke Middletube.

Here is a simple look at how fixed windbreaks compare to dynamic curtains, and why getting your airflow right matters.

1. Fixed Windbreaks: Simple and Reliable

Fixed systems, such as the Secure Windbreak System or the Vervaeke Fixed Windbreak, give you permanent, strong protection for exposed end walls and side openings.

• How They Work: Made from tough, wind-permeable mesh, these systems cut harsh winter winds by up to 80%. They let fresh air drift through while keeping out driving rain and sleet.
• The Pros:
  • Extremely durable with no moving parts, motors, or ropes to wear out or repair.
  • Very cost-effective for long-term protection.
  • Ideal for exposed, high-ground sites that face constant rough weather.
• The Cons: They give you a fixed level of cover. While they block harsh winds well, you cannot open them up on mild autumn days or close them completely during a heavy blizzard.

2. Adjustable Ventilation Curtains: Flexible Control

When you want the option to adjust to changing day-to-day weather, curtain systems are the better fit. Solutions like the Airkoe Safe System or the Vervaeke Middletube give you full control over the building’s internal climate.

• How They Work: Powered by central drives, cables, or rolling tubes, these tough canvas curtains move smoothly over large openings so you can adjust airflow as needed.
• The Pros:
  • Total Flexibility: Open them to clear out humidity on warmer days, or close them tight when heavy winter storms roll in.
  • All-Season Use: They help a single shed handle both warm, muggy periods and freezing winter weather.
• The Cons: They cost more upfront and require occasional checks on winches, wires, or automatic control systems.

Fixed Windbreaks vs. Curtains: Which Should You Choose?

• Choose Fixed Windbreaks (like the Secure or Vervaeke systems) if you have specific walls that take a beating from the wind, or if you want a simple, maintenance-free barrier for open-sided storage or general bays.
• Choose Adjustable Curtains (like the Airkoe Safe System or Vervaeke Middletube) if you run high-yielding dairy herds or sensitive calf-rearing units where stopping drafts and controlling exact air movement is vital for herd health and yield.

Managing Airflow Direction: Avoiding Winter Draughts

Whether you install fixed mesh or adjustable curtains, where air enters the shed matters immensely.

Bottom-opening curtains are highly effective for maximising low-level air movement during warmer seasons, helping clear heat and humidity from animal level. However, using them in winter requires careful management, as opening from the bottom can direct cold draughts straight into resting areas, increasing the risk of chilling and respiratory stress for stock.

Top-opening or high-level airflow during colder months allows incoming fresh air to enter near the eaves. This gives cold air time to safely mix with warmer, rising air inside the shed so it tempers before reaching your livestock.

Combining high-level air entry with ventilating light ridges at the peak further enhances overall ventilation by drawing out stale air while brightening the interior.
