Healthy outdoor climate management in the group igloo

The large-capacity Holm & Laue Igloo allows calves to be reared in a healthy environment, which also results in low barn construction costs. Calves that grow up in the fresh air are healthy and perform well. Moreover, they grow up in the Holm & Laue Igloo in social groups of up to 15 animals. The Igloo demonstrates its flexibility time and again, whether with the mobile Veranda, in the IglooSystem (a stationary calf village) or as an extension to an existing calf barn.
This makes the Igloo the ideal basis for successful calf husbandry. The Igloo is extremely durable and long-lasting due to the high-quality fibreglass used in its construction. You and your calves will appreciate it for a long time.
An innovative ventilation system in the spherical Igloo ensures fresh air at all times, reducing respiratory diseases in your calves. We also recommend that you provide a covered exercise area – such as the IglooVeranda – to give your calves the choice between the sheltered igloo and an open-air resting area in front of

A place of retreat for your calves

Everyone knows that draughts in your calves' resting area stress them and make them sick. On the other hand, conventional calf barns need a high air flow rate to replace stale and contaminated air. Especially calves in the first weeks of life that cannot yet compensate for these negative influences through their own body heat production. You can offer up to 15 calves a draught-free yet well-ventilated shelter with the large-capacity H&L Igloo.

Unique ventilation system and perfect temperature

The hemispherical shape of the Igloo ensures ideal ventilation: wind sweeping over the outside of the Igloo creates negative pressure at its highest point (Bernoulli’s principle). Stale air is actively drawn out of the Igloo. Since the inlet opening is 12 times larger than the exhaust openings, the air velocity in the resting area remains extremely low. There are therefore no undesirable draughts in the calves' resting area.

A special coating on the Igloo ensures maximum reflection of solar energy. For this reason, the Igloo does not heat up unnecessarily even on hot summer days and offers the calves a cool resting area. Even in winter, the temperature inside the Igloo hardly differs from the temperature outside. The animals do not start to sweat, which would lead to considerable problems.
