Schwegler 1FE Bat Access Panel

The Schwegler 1FE Bat Access Panel is a maintenance-free access unit designed to retain and protect existing bat roosting spaces within buildings during renovation, conversion, or insulation works. Particularly suited to older and historic buildings, the 1FE allows bats continued access to established wall cavities while helping maintain roost continuity during building upgrades.

The unit features an open-backed design, enabling bats to access existing voids within walls. With a depth of just 80mm, it can be easily integrated into masonry, insulation systems, or rendered facades with minimal visual impact. Installation of multiple units is recommended where larger roosting opportunities are required.

Manufactured from durable SCHWEGLER wood-concrete, the 1FE provides excellent weather resistance, thermal stability, and a rough internal surface to assist bats with grip and access.

Optional Accessory

The optional Schwegler 1FE Back Panel converts the unit into a standalone bat box by creating an enclosed internal roost chamber.

Suitable Species

Building-dwelling bat species.

Siting

The 1FE should be installed at least 3 metres above ground level with a clear, unobstructed flight path for approaching and departing bats. It can be built into exterior walls or fixed directly to masonry using suitable screws and plugs.

The shallow profile allows easy incorporation into insulation layers or brickwork. Care should be taken to avoid creating access into breathable roofing membranes or unsuitable building voids.

Positioning close to existing bat access points, feeding routes, or known roost locations will improve the likelihood of occupation.

Maintenance

The 1FE is maintenance free. Droppings fall naturally from the entrance opening, so routine cleaning is not required.

Why protect bat roosts?

Bats and their roosts are protected under UK wildlife legislation. Renovation and insulation works can result in the loss of important roosting spaces within buildings, particularly in older structures. Integrated access panels such as the 1FE help retain existing roost opportunities while allowing building improvement works to proceed sensitively.
