Bat Winter Roost 2WI

Bat Winter Roost 2WI with constricted entry 

2WI with optional rear panel (Order No. 00 778/0)


Winter Bat Roosts for attaching on and installing in façades

Due to their special insulation, the Winter Roosts 1WQ and 1WI are suitable as a place for building-inhabiting Bat species to live not only in the winter but also in the summer. Thanks to the patented double-panel system, these roosts are suitable for winter. This system has been used successfully for many years in our Bat Hibernation Box 1FW for forests and woods. Together with the insulation material used, the design ensures excellent insulation properties while at the same time remaining very breathable for decades. Both roosts have been improved continuously in lengthy test series. They are self-cleaning and are therefore maintenance free. These all-year round roosts are made for safe colony and nursery roost formation in the summer and for safe winter hibernation of the animals.

Installation: On façades, 3 m and higher. Ensure unobstructed approach and departure.
Typical building-dwelling Bat species are, among other things: Pipistrelle, Serotine or Particoloured Bats.




Bat Winter Roost 2WI

with constricted entry · All-year roost for flush installation in walls


Model 2WI has a constricted entrance opening at the front (vertically to approx. 23 mm) to minimise the penetration of water, especially for locations exposed to the weather. Otherwise Models 1WI and 2WI are the same. For description and attachment details, set Model 1WI. If installed flush (in-wall), please note that moisture can occur in the interior. If installed on sides of the building exposed to heavy rain, we recommend use of the optional rear panel (Order No. 778/0). This minimises the penetration of moisture into the building insulation/masonry.

Material: Weather resistant and breathable lightweight concrete.
Total dimensions: W 34.5 x H 54.5 x D 9.5 cm. Weight: approx. 15 kg.
