High stability and durability are ensured by manufacturing from high-quality, impact-resistant HDPE plastic with integrated UV stabilizers. The hut entrance threshold, reinforced with steel tubes, ensures a high level of stability. Optimal climate control of the Calf House is achieved via the adjustable ventilation flap that can be fixed at all levels. It also facilitates the filling of the hayrack. The especially smooth interior surfaces make cleaning child's play and thus improves hygiene. The increasing roof slope with ventilation openings ensure optimum air circulation so that humid air can heat escape at the top. Higher insulation effect and service life due to additional UV protection. The opaque CalfHouse PE UV+ is equipped with integrated UV stabilizers. The solar radiation is thus better absorbed, so that the interior of the calf hutch does not heat up so much. in addition, the natural degradation of the material is reduced Bucket, feed box and hay rack not included in scope of delivery.
