The 3CHWB is a 3-layer built-in bat box made from durable wood concrete. The modular design has been specially developed for bat species that inhabit buildings. It is particularly suitable for the common pipistrelle and Nathusius’ pipistrelle. The box may also be used by serotine bats, brown long-eared bats, and pond bats.
The box is designed for installation within masonry. When combined with an entrance stone, it can be fully integrated behind the brickwork. Alternatively, it can be partially installed with brick slips applied to the front.
Thanks to the modular system, multiple boxes can be connected. This is done via pre-formed openings that can be easily removed, allowing the creation of larger roosting spaces.
This version is the 2-layer model. The same design is also available in 1-layer and 3-layer variants. This box may serve as a permanent summer/mating roost for the Nathusius's pipistrelle. When this box is connected vertically, it also complies with the BIJ12 measures for the Common Pipistrelle.* For direct compliance with the measures for the Common Pipistrelle, tall built-in boxes are also available.
Specifications 3CHWB:
External dimensions: 21,5 cm × 48,2 cm × 11,5 cm
Internal depth per layer: 2.4, 2,4 & 2,5 cm
Weight: approx. 6 kg

Mounting
* The entrance hole measures 3 centimeters. As a result, the box may be less suitable as a summer or mating roost for common pipistrelles, but it is usable for other (larger) bat species. Nevertheless, the box meets the minimum requirements as described in the BIJ12 knowledge document on the Nathusius's Pipistrelle.
