Barn Curtains

Barn curtain for natural ventilation

Cows are northern animals; they prefer a dry, cold environment to a hot, humid one. Barn curtains provide the fresh air exchange that cows need, protect them from heat stress, and ensure healthy, clean airflow. Barn walls should be openable so that the animals can breathe easily. The curtains should create a climate inside the barn that meets the needs and welfare of the animals.

The main purpose of stable curtains is:

1. Breaking the wind (It’s not the cold air, but the wind that makes the animal cold and sick)
2. Creating shade (Animals prefer shaded and cool areas to avoid thermal stress)
3. It prevents birds from entering the barn (Birds eat the most valuable grains of food, carry diseases, and contaminate the barn with their droppings).
4. The goal is to provide natural ventilation. ( Animals need clean, plenty of air.)

Barn curtain for natural ventilation.

Barn curtains provide fresh, clean, dry air and a cool environment with natural ventilation inside the barn. These barn curtains are durable, seamless, fire-resistant curtains that block wind and contribute to barn ventilation and lighting. They are an essential piece of barn equipment that enhances animal welfare and comfort while providing natural ventilation and lighting.

• Protected from wind (Wind is one of the most important factors directly affecting animal health)
• It should be permeable enough to allow sufficient and clean air to enter.
• The cattle need to breathe; their air needs must be met.
• It prevents birds from getting inside.
  • Birds choose and eat the most valuable grains of their food.
  • This prevents bird droppings from mixing with the feed and protects against diseases carried by birds.
  • Birds consume about 30% of their own weight in feed each day.
  • An adult sparrow weighs 25-28 grams.
• We must prevent the weather from getting hot.
  • Warm air rises, and the rising air must be allowed to escape through the upper openings.
• We must prevent the accumulation of polluted air.
  • (We must allow the polluted air to escape)
• It should provide shade and protection from the sun.
  • Sunlight increases ambient temperature and thermal stress, reducing milk yield.

It provides visual and aesthetic enhancements. It covers up visual pollution.

Natural ventilation in barns.

In the past, barns were isolated by thick walls. This meant the animals had to carry out all their activities within the same enclosed space and climate conditions.

Cattle’s need for air

When calculating air requirements, it is assumed that human lung capacity is 6 liters, horse lung capacity is 50 liters, and cattle lung capacity is 13-16 liters, taking into account the respiration rate (number of breaths). The total respiratory capacity of an adult Holstein Friesian cow is approximately 136–170 liters per minute (tidal volume is 7 liters), and the breathing frequency is approximately 24–40 times per minute.

For example, a milking cow needs about the same amount of air as 40 people. The air in the barn needs to be changed 6-8 times per hour. Therefore, the use of ventilation curtains and fans to support air circulation is unavoidable on farms. If a cow is breathing more than 80 breaths per minute, this indicates heat stress.

“An adult needs 30 cubic meters of clean air per hour. Under normal conditions, it is assumed that the air in the environment is changed 2-3 times per hour with natural ventilation. The air volume per person in workplaces should be 10 cubic meters.”

Cattle that cannot breathe clean air also suffer from poor health. To help you achieve high yields with proper and healthy climate control, there are various powerful and quiet fan options available in different designs. A good climate inside the barn is essential for high cow comfort, and barn ventilation systems are a fundamental requirement.

The barn walls should be able to be opened so it can breathe.

The curtains should provide the cow with the necessary fresh air exchange in the form of a natural breeze; this is the only way to avoid heat stress. In winter, a modern farm needs to be ventilated 4-6 times an hour with sufficient air intake. In summer, it is necessary to reduce the animals’ body temperature as much as possible, so the barn should be ventilated 60-100 times an hour.

Stable curtains and systems

Curtain dyes have significantly higher UV resistance due to their sunlight-reflecting properties, resulting in a longer lifespan compared to other curtains. Transparent curtains, because they allow light to pass through, are directly exposed to UV rays and therefore wear out faster. VERVAEKE revolutionized barn climate control in Europe.

MAXI system barn curtain

While providing natural ventilation and lighting for the barn, it enhances animal welfare and comfort. The special double-layer curtain system MAXI: A fire-resistant, seamless, durable curtain that refracts wind and light, contributing to barn ventilation and lighting, and an integrated BIRD curtain, prevents birds from entering the barn.

Assembly and Installation

The Maxi System is controlled by a chain-driven system at the top and bottom . Belts are mounted on the upper axle, running the entire width of the system, ensuring smooth fabric retraction. Two patented spring elements are located on the left and right sides of the fabric’s lower tube. It remains resistant to high winds, air intake is at the top, and contributes to optimum barn ventilation.

For maximum windbreak, the netting is fixed to an aluminum frame and mounted in front of the netting wall. This keeps birds out. If the system operates automatically via remote control or computer, the bird cage provides extra security. It prevents access to the rotating roller and minimizes the risk of accidents. When the bird netting is mounted outside the opening, the rain netting may naturally need cleaning.

The system is integrated seamlessly into the existing structure; only a 20 cm gap at the top and a 35 cm gap at the bottom are required for mounting.

Animal Comfort, Barn Curtains, Cows love freshness

The ventilation system in modern loose-stock farms and Barn Curtains Fireproof seamless barn curtains that break the wind and contribute to the barn ventilation and lighting. While providing natural ventilation and illumination of the barn; Improves animal welfare and comfort.

Over the past 10 years in the cowsheds of Europe there was a climate revolution. Before this, the farms were heavily lined with walls and isolated better than some residential buildings. This was due to the fact that all areas of activity were in the same room. Today, we divide the dairy farm according to the functional areas, and the loose-stock farm is now primarily a place for rest and feeding the cow.

Animal needs fresh, dry, clean and cool air that curtain provides

1. To prevent Wind (Wind is most dangerous air circulation for animal health)
2. To prevent sun light (Sun light increases heat in the barn which causes heat stress and reduces milk yield)
3. To prevent heat ( heated air in the barn rises and has to leave from top openings)
4. To prevent dirty air ( exchange air lets exhausted heated air from top and lets in fresh air through curtain)   
5. To prevent birds come in barn ( to save food staff eaten by birds and to get rid of bird shit and bird born deceases).

The climate of the cowshed should be 100% meet the requirements of the dairy cow. The cow, in its essence, is a northern animal and prefers a dry cold environment to the warm and humid.

Lack of fresh air means:

Heat stress, cows become sluggish, eat less food and itch to give off body heat, instead of chewing. If the temperature rises from 20 ° to 30 ° C, then the cow is undernourished with at least 1.5 kg of dry food and produces 3-5 kg ​​of milk per day less.
When the humidity of the air increases, the animals have difficulty in the summer with the heat transfer of their bodies, and in the winter they catch cold, as the wool becomes wet. Pathogenic pathogens spread much faster in moist air. Dust from the food and litter aggravates breathing.

Harmful gases such as carbon dioxide, ammonia and methane also weighed animals. With a lack of oxygen, it is impossible to achieve high productivity.

The cowshed must be able to open the walls by Barn Curtains

This requirement can be met if the side walls of the loose-fitting farm can be opened. The opening must be such that the cow can be air-blown at the height of summer. This is the only way to avoid additional heat stress. Approximate dimensions for the opening of a detached building are required on each side of 0.6 m² per cow, to protect against wind in other premises it is necessary about 1 m² per cow. From this it follows that in a six-row farm of loose-fitting content the height of the overhang of the roof should be from 3.40 to 5 m with an opening from 2.70 to 4 m.

Feed kitchen and robot housing curtain and doors

The feed kitchen is the area in which the feed is stored, selected, picked up and loaded into the robot for mixing. In the kitchen, a crane construction with a feed grabber is installed that moves above the kitchen to the right block of feed. Depending on the width and depth of the kitchen, it can easily stock feed for three days. Automatic feeding Automatic feeding means that cows are fed with precision. You will need adapted door and curtain system will work with robotics.

The color is entirely related to preference.

Due to its ability to reflect sunlight in curtain paints, UV resistance is much higher and therefore its service life is higher than other curtains. Because transparent curtains pass through the light, they are directly exposed to UV and therefore age older.
